This last week, I decided that now was the time to find out more about Alli. We dug through the ingredients, side effects, customer service reports and even clinical studies. Then, we looked around the web for reviews on the product. Finally, we refined and condensed to give you the bottom line.

Alli Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Alli?

First off, Alli is a lipase inhibitor. [1] The active ingredient is orlistat. [2] If you take one pill with each meal, it supposedly reduces the amount of fat absorbed and blocks about 25% of the fat you eat. [3] That equates to about 100 calories a day. The bottle is small, and there is an easy carry container in some starter kits.

Alli is made by GlaxoSmithKline, which was founded in 2000. You can purchase supplement at local grocery stores and through trusted retailers. We like that the product is FDA-approved [4] and there are reports of weight-loss, but read on…

Alli Side Effects – “Worth It?”

The first negative relating to Alli side effects was the intensity. “If you take the medication regularly you can expect less fat to be absorbed, but there’s a catch,” said our Research Editor. “If you eat too much fat, you may have to deal with gastrointestinal issues.” [5]

“I have experienced one accident with a BM,” one user said. “I really have to watch what I eat or I will pay for it later.”

Another offered, “I have had a rough time with not being able to be too far from a rest room.”

Not all users had the same problems. Some, as a matter of fact, ate high-fat meals and experienced no side effects. “I decided I would eat a fatty meal to test the effectiveness so I got a fast food combo, came home, took a pill, then ate. Nothing happened. No side effects, nothing,” according to one user.

“I found that the only side effect was my systolic and diastolic levels were reduced,” commented another. [6]

Alli Customer Testimonials

Cost – “A Bit High”

Another issue we found dieters did not like about Alli ingredients was the cost. “This has absolutely no effect on me whatsoever and I have the most sensitive stomach of all the people I know. Waste of $60,” said a customer.

“Not as much weight as I’d like to have lost for a $150 cost, at this point, four months in,” was one experience.

There are some dieters who felt the money was well spent, “You will see faster results such as lowered ldl cholesterol [7] if you include exercise and vitamins. Worth the price.”

We’ve found that over the years there’s been a logical connection between small things, like side effects and a lesser chance of long-term results. If Alli causes adverse reactions, that could be enough to scare dieters away.

The Science – “Any Clinical Proof?”

Unlike many other weight-loss solutions on the market, Alli is clinically proven to work. However, at the maximum amount of fat grams, you will reduce calories by about 100. The real key is eating a healthy diet and exercising while using the supplement. [8]. There’s also the chances of negative side effects affecting the functionality of the bowel system and intestines. [9] At DietSpotlight, we think science should do more than proving you have to cut fat or suffer the consequences.

The Bottom Line – Does Alli Work?

Are we running out to the store right this minute for Alli? Well, we certainly like the fact that the FDA has approved the medication and there’s no doubt it can block up to 100 calories a day, but we’re hesitant about recommending it because of the risk of side effects. Bowel leakage [10] is an extremely embarrassing situation, and we’re not sure it’s worth it when there are clinically proven options with no adverse reactions.

If you want to get off that extra fat, we suggest going with a product that’s been tested and proven to help you reach your goals without risking the embarrassment of some gastrointestinal side effects.

Among the best products we’ve seen this year is our supplement called Dietspotlight Burn. This formula contains four ingredients. All clinically-tested with results often seen in publications such as the Journal of Medicine and the journal Obesity.

Plus, we’re so confident that you’ll love our supplement that we’re offering a Special Trial Offer, which is a good sign.

Previous Alli Review (Updated September 20, 2012):

Alli - What You Should Know

Alli is a diet supplement that endeavors to assist with weight loss. This product was developed and manufactured by the major pharmaceutical company GlaxoSmithKline. The Alli diet pill is stated to be FDA approved and is commonly available without a doctor's prescription. The official Alli website addresses the supplement as an "anti-obesity wonder drug." It additionally discusses the "65 percent" of American adults that are currently overweight. Alli diet pills can be purchased through the official website for $44.99 for a 60 capsule starter container. Alli is claimed to be more effective when taken in conjunction with a healthy diet and regular exercise regimen. Alongside a healthy diet and exercise, Hydroxycut is a thermogenic for men and women to boost the metabolism, increase energy levels and assist with weight loss.

The key active ingredient found in Alli supplements is called Xenical (or Orlistat), which is a prescription weight loss drug. This diet pill aims to minimize the body's fat absorption or block a good 25 percent of fat that's consumed. Some potential side effects that can occur are a vitamin deficiency, "loose stool" and excessive gas (flatulence). Alli can be purchased in most common drugstores and superstores across the US. This diet supplement is claimed to alter the process of triglycerides being broken down inside the body by obstructing an enzyme, which is found in the pancreas. This process prevents fat absorption. The Alli Diet Pill is marketed toward both men and women who are suffering from obesity and other individuals who are borderline obese.

List of Ingredients in Alli

Orlistat 60mg, FD&C Blue 2, Edible Ink, Gelatin, Iron Oxide, microcrystalline cellulose, Povidone, Sodium Lauryl Sulfate, sodium starch glycolate, Talc and Titanium Dioxide.

Product Features

Alli is a weight loss supplement that comes in capsule form available over the counter in pharmacies and drugstores around the United States. This "wonder drug" is claimed to cut fat absorption by 25% so that the user absorbs fewer calories from what he/she eats. A key active component of the Alli diet pill is Xenical, which is also known as Orlistat. Alli is intended for adult women and men and is directed to be taken daily with water. This diet product sells for $44.99 via the official website. Like many other weight reduction supplements, a healthy diet and routine exercise are encouraged. Flat Tummy Tea is another alternative that can be mixed in a glass to increase energy and burn more calories for weight loss.


  • Alli is available to men and women that suffer from weight issues.
  • Alli diet pills do not require a doctor's prescription.
  • Alli is approved by the FDA.
  • Alli Diet Pills can be easily and conveniently purchased via the official website.


  • Consumer testimonials are absent from the official Alli website.
  • The official Alli website fails to offer a 100% money-back guarantee.
  • Some individuals may be allergic to certain ingredients found in Alli Diet Pills.
  • Alli does not offer free trial samples on the official website.
  • No before and after photos are provided on the Alli website.
  • May cause digestion discomfort. (See reader comments.)
  • Taking Alli Diet Pills can potentially result in a vitamin deficiency.

Our Conclusion on Alli

It should be noted, Stacker 2 is also a fat burner with few natural ingredients that can easily be taken on the go for weight loss. On the bright side, the Alli diet supplement is approved by the FDA. Since many other diet supplements, programs and pills aren't FDA approved; some consumers may find this approval reassuring. However, some dieters would likely be more interested in Alli supplements if the official website posted some consumer feedback, a money-back guarantee or at least a few before and after photos. Be sure to consult your doctor before taking Alli diet pills. This way you can learn more about potential side effects and other diet supplements currently available. Before you close out of this review, you might want to consider Phentabz as an alternate source as it is a fat burner that contains DMAA, caffeine, and synephrine used to burn off fat.

Alli is an over-the-counter version of Orlistat, which was originally offered as a prescription medication. It is clinically proven to bind to some of the fat you consume and flush it out of the body when you have a bowel movement. Eating excessive fat, more than 15g in a meal, can result in side effects.

Alli Ingredients and Supplement Facts

Serving Size: 1 Capsule
Serving Per Container: 120
Amount per Serving% DV

Other Ingredients: Edible ink, gelatin, iron oxide, microcrystalline cellulose, povidone, sodium lauryl sulfate, sodium starch glycolate, talc, titanium dioxide

We researched Alli ingredients to give you the important specifics you need.


To start with, Orlistat is commonly sold under brand names such as Alli (over-the-counter version) or Xenical. [1] It is a prescription drug for weight-loss. It’s typically taken with doctor-approved exercise and a reduced-calorie diet plan.

What is it Supposed to Do?

Orlistat essentially prevents some of the fat you consume from being absorbed by the body. Instead, the excess fat is flushed out through the digestive tract. While this treatment for obesity is FDA approved, it can lead to some side effects like stomach pains, oily or fatty stools, gas, and spotting in your undergarments.

Clinical Research

According to the Mayo Clinic, “People who ate a calorie-restricted diet, exercised regularly and took Alli (Orlistat) lost an average of 5.5 pounds (2.5 kilograms) more in one year than did people who only dieted and exercised.” [2]

FD&C Blue No. 2

FD&C Blue No. 2 is an inactive ingredient found in various pharmaceuticals, dietary supplements, cosmetics and manufactured foods. It is regulated by the FDA and is considered harmless.

What is it Supposed to Do?

The only purpose of FD&C Blue No. 2 is to function as a colorant. This is why it is often used in tablets and capsules.

Clinical Research

There is no clinical data that supports FD&C Blue No. 2 as an active ingredient for fat loss or weight reduction. However, this substance has been researched and is considered safe as a colorant.

Edible Ink

Edible ink is often used in the manufacture of capsules, tablets, confectionary products and other foods. It is considered safe for consumption but does not serve as an active ingredient.

What is it Supposed to Do?

The only real purpose of edible ink is to provide color to pharmaceutical capsules, dietary supplements, pastries, candy, cakes, cookies and other foods. It is often printed on edible paper made from rice.

Clinical Research

There is no published clinical research that supports edible ink as an effective weight-loss ingredient. On the other hand, this ink has been deemed safe by the Food and Drug Administration for consumption as a food coloring.

Alli Side Effects:

In the world of weight-loss products, the words “natural” and “herbal” are often thought also to mean safe. Unfortunately, for every formula comes the potential for issues. Though Alli side effects are not guaranteed, that doesn’t exist for some that use its supplements.


Gas is a feeling of expelling air from the gastrointestinal distress through the anal cavity. Other symptoms that can be experienced along with this one may include cramps, swelling, tightness in the abdomen, and sharp pains.

What causes gas?

Gas occurs to everyone, even if it isn’t noticeable. However, it can become uncomfortable or more frequent, especially if some individuals start consuming more high fiber foods [1]. Other reasons include swallowed air, health conditions, food intolerances, especially in herbal supplements, sweeteners, and constipation.


Bloating is usually connected to other symptoms, like gassiness and abdominal discomfort. It can also cause the appearance of weight gain.

What causes bloating?

Overeating, fatty foods, and simply eating too fast are the three most common reasons for the onset of bloating. When it happens temporarily, it should not be of concern, but it is important to seek medical attention if it is related to other, more severe symptoms or lasts for an extended period.


Diarrhea is a condition in which fecal matter is loose, watery, and can occur more frequently than usual. Although it is normal for this to last a couple of days, it can be considered an issue if it lasts any longer. Cramps, pain, a lack of bowel control, and an increased need to make a bowel movement may also occur with this symptom.

What causes diarrhea?

Some causes of diarrhea may include bacteria, viruses, medicines, herbs, food intolerances, small intestinal diseases, and issues with the colon.

Bowel Leakage

According to the National Association for Continence, bowel leakage can be characterized by having trouble holding a bowel movement, having liquid stools leak from the anus, and finding streaks of fecal matter in underwear [2]. Although it does affect both men and women, it usually occurs in the older population.

What causes bowel leakage?

Diarrhea, constipation, aging, childbirth, medication, and more are some causes of bowel leakage. Other, more severe issues may also cause the onset of this symptom.

Alli side effects are not felt by all its consumers, but there have been reports gas, bloating, diarrhea, and bowel leakage, just to name a few. To protect yourself from potential problems, it is always the best idea to consult with your physician before taking any supplement, especially if you’re taking prescription medications, are under 18, have a medical condition of any kind or are pregnant or nursing.



Alli has been around for quite some time, but we’ve heard rumblings from dieters wanting to learn more about Alli side effects. (Feel free to read our full Alli review.) We chose to look hard at the ingredients and clinical research. We also read hundreds of dieter comments to see what was happening with regular use. That information was condensed to give you the bottom line.

What You Need to Know

First off, Alli is an over-the-counter version of Xenical, a prescription weight-loss medication. You take the pill three times daily, one before each meal. It is supposed to reduce fat absorption by 25%, based on clinical studies, so this could lead to increased weight-loss. You can find a small take-along case, so you have Alli when you need it.

The product, offered up by GlaxoSmithKline, is an over-the-counter variety of Xenical or Orlistat. The ingredient has been clinically tested and approved by the Food and Drug Administration, quite the positive. It’s available for sale online and in many stores. We like that some dieters have reported weight-loss and the FDA has given it a thumb up, but read on…

Constipation – Surprising Issue

The first issue we found interesting about Alli side effects was reports of constipation. “Alli is associated with loose stools,” says our Research Editor. “We found it quite surprising that dieters claimed to suffer from difficulty using the bathroom.”

“I have been taking Alli for about 2 weeks now, and my side effects seem to be the opposite of everyone elses. I makes me very constipated. Has anyone else experienced this?,” says one user.

“I have been on and off Alli for the last few months. It made me constipated – I NEVER suffer from constipation,” offers up another.


The most common Alli side effect is diarrhea. This is associated with the way Alli works. It traps fat and pushes it out through the intestine. “I got so tired of ruining my underpants and rushing everywhere because I had to hit the bathroom whenever I was standing for a while that I had to stop taking this stuff,” reports one dieter.

Accidents are common, as claimed by another user, “I made the mistake of eating Chinese food and had a MAJOR accident at work the following morning! I WAS MORTIFIED TO SAY THE LEAST!!”

It’s with research behind us that we suggest a connection between adverse reactions, like diarrhea, and lesser chances of long-term success. If Alli side effects cause problems with dieters, that’s not exactly a benefit.

The Science

There is clinical research backing Alli weight-loss claims – there has to be because the FDA approved the drug. The benefits, however, may not be worth the Alli side effects. It is recommended that you eat no more than 45 grams of fat each day. That adds up to 405 calories. Twenty-five percent is about 101. At that rate, it would take 34 days to lose a single pound. At DietSpotlight we want science to set a product apart from other solutions. Alli just doesn’t fall into that category.

The Bottom Line

We were intrigued by Alli side effects, and with a little research, we found what we needed. We like that some users report weight-loss while on the medication, and it has been approved by the FDA, but we can’t recommend a product that only equates to the dieter losing one pound a month. We’re also concerned by the frequent reports of diarrhea and leaky bowels that cause “accidents” when least expected.

If weight-loss is at the top of your priority list, we suggest going with a supplement that doesn’t come with harmful side effects but does come with clinically proven ingredients.

Among the best supplements we’ve come across this year is Dietspotlight Burn. We like the proprietary blend of four ingredients clinically proven to help speed up metabolism and boost fat loss. We didn’t find a single report of adverse side effects, but we did find numerous dieters talking about great results.

Also, the makers of Dietspotlight Burn are confident enough in the formula to offer a Special Trial Offer, impressive.

The only Alli ingredient is orlistat. [1]

Does Alli work?

Alli Scientific Abstracts:


Orlistat has been shown to have weight-loss effects by suppressing absorption of consumed dietary fat (by ∼30%). Following one and two years double-blind, placebo-controlled trials, the safety, and efficacy were determined with adverse effects being mostly gastrointestinal. Because orlistat has fat absorption capabilities, it is also able to suppress absorption of fat-soluble vitamins. It was because of this finding that it was suggested that vitamin consumption is recommended while taking orlistat. The research concluded that orlistat, through the absorption of fat, delivers a new treatment for weight-loss and weight management. Further studies are suggested during post-marketing surveillance to establish orlistat’s safety and benefits in the long-term. Orlistat is a useful tool for weight-loss in obese patients who can make alterations to their diets, exercise, and behavior. [1]

Orlistat has shown to be a useful adjunctive treatment for triggering weight-loss as well as improving serum lipid levels, blood pressure and glycemic control in obese individuals with type 2 diabetes already taking metformin. [2]


Data on the effects of orally ingested gelatin shows that gelatin strengthens fingernails as well as improving nail defects. The data prompts a discussion regarding the action gelatin has on nails most likely occurring via the metabolism of amino acids for what appears to be the specific dynamic action of gelatin. [3]

Sodium Lauryl Sulfate

Sodium lauryl sulfate delivered total protection of viruses in cutaneous-infected animals. Sodium lauryl sulfate completely prevented cutaneous lesions on mice that were pretreated with a sodium lauryl sulfate polymer formula. Intravaginal pretreatment with sodium lauryl sulfate within a buffered solution had protected against HSV-2 infection. It was concluded that sodium lauryl sulfate might be a useful tool as a microbicide in preventing sexually transmitted disease such as HSV, HIV, among other sexually transmitted disease-causing pathogens. [4]

Titanium Dioxide

Titanium dioxide nanoparticles were found to trigger pathological lesions of the kidney, spleen, liver, and brain when exposed intravenously. The data suggested that the significant effects could be caused by extremely high doses of titanium dioxide nanoparticles. Although titanium dioxide nanoparticles are being produced and used at a more rapid rate, there is a significant lack of epidemiological data backing it. Titanium dioxide nanoparticles have been studied thoroughly. However, the evidence is lacking regarding the possible health effects of backup risk assessment and management. [5]

  Does it effects health?
Bonnie (Verified User)

I’m 19 and my doctor gave me this pill to lose 80 pounds. Everyone I know is completely dumbfounded that a doctor would give someone this medication (seven day trial). My mom says it does nothing but make you run to the bathroom non-stop and it’s not worth my money. Help?

Victoria (Editor)

HI Bonnie,
Keep in mind that everyone’s results with Alli will vary. It is a supplement to help you lose weight but it works best and is supposed to be used while exercising regularly and maintaining a healthy diet. It may also increase the amount of times you use the bathroom a day.

Victoria (Editor)

Hello. All users are different and can experience different weight-loss results.


I started Alli when it first came out and lost 30lbs in 3 months and took one here and there is I was eating a bad meal. I kept the weight off for 2 yrs. I stopped taking them all together because my hair starting falling out and breaking off. My hair is ruined. I took the vitamin and everything. My hair didn’t start falling out and breaking for about a yr or so after being on them. I wouldn’t take them. I haven’t cut my hair and have lost 5 inches due to it breaking off.

  Which vitamin should take with the product.
Deann Ficken

What kind of vitamins should I take while on Alli?


Fat soluble vitamins are Vitamin A, D,E, and K, so a multivitamin with those vitamins in it is a good idea.

Candace (Editor)

This company actually addresses this problem and claim they have made no changes to the formula since 2007 and have maintained it’s original efficacy. Oddly several dieters say otherwise.

Is there any possiblity of liver damage?

Is there any possiblity of liver damage? I do take a multivitamin every night. Is there a limit on how long you can take it. i.e, to help maintain the goal weight?


yes, liver damage is possible in the form of hepotoxicity (toxic dose which effects the liver) the level of alli taken (if following the directions) should in fact keep you in the therapeutic range. Just dont take more the directed and like anything you take dont for excessive periods of time (longer then 4 months)

Victoria (Editor)

Hi Sallie,
Everyone will have different results from Allis. If you are concerned, we recommend that you talk to your physician before taking Allis.


I recommend taking a break after you finish each bottle(around 1 month).You body has to have balance and using that product every day for years will cause side effects!

  can Ali be taken if you've had your gallbladder out?

Hi Linda, we do not recommend using this product with a recent operation. Please consult with your physician about this. Hope you’re recovery goes well!


Im trying to find out the same thing… been taking it a few days… but since I dont have a gull bladder I already dont have the enzyme that breaks down fat from it… I have a dairy free diet… and so that makes it a pretty low fat diet. Just wondering if anyone has had bad effects without a gull bladder.

  Can take with other supplement?

Looking for info on taking Alli after bariatric surgery, Roux-en-Y gastric bypass. Has anyone tried this? I think extra vitamin supplements would offset the possible effects of malabsorption.

for how long can I take alli? is it safe to use it monthly?

Victoria (Editor)

Hi Michelle. When you order Alli it will come with a four month supply.


I’ve been taking alli for about 2 weeks now and I haven’t had any bad toilet trips, I’ve just had really bad gas really smelly ones.


Yes, Alli DID work. I lost a lot of weight gradually over 2 years. However, the last year or so I have purchased Alli, Orlistat, Xenical etc at great cost. It now has no effect whatsoever. I am assuming the ingredients have changed since a major re-call a few years ago. Such a shame, as was the only “safe” diet pill on the market.


I have been using Alli for several months now. This last bottle seems to have no effect. I opened one of the capsules and it is chunks of white stuff, instead of powder. It is like there is no Orlistat in them.
Sorry if this seems crass, but when the stuff is working, my BM’s float. Has anyone else gotten bad bottles??


I too have had an accident a couple of times with the oil coming out. If it’s a lot it does smell. I can’t describe it. Not like poop. If you have just a small accident know one would know. If it blows out all over like if you fart and it sprays out then yes it would leak through your underwear and it would smell more lol. It’s orange and just like oil. It’s so weird. I’m unsure about taking this. I have been for about a week now but I only need to lose 10lbs and I’m not overweight just for me. Haven’t lost any weight yet.

Alicia (Verified User)

Im 222lbs. I started Alli yesterday. 3 tablets with my meals which were moderatly fatty. Today i had pretty much the same semi unhealthy things but all Ive got is rumbly gurgling sounds in my belly and no urge for the toilet. Is this normal? Shall I wait a few more days…?

Stephen (Editor)

Hey, Alicia. Please make sure to consult with your physician if your side effects continue.

  Product just wasn’t for me
Christy (Verified User)

ive been taking for about a week now and I know I don’t eat a lot of fat during the day so the pills haven’t really done anything but last night I had prociiutto cheese pizza and It took almost 7 hours for me to finally go to the bathroom?? Shouldn’t the pill have worked quicker on such a fatty dinner??


But did you have an oily discharge?

Victoria (Editor)

Hi Christy,
It depends on how fast your metabolism is.

  Alli really helped me lose weight.
Linda (Verified User)

I have used Alli in the past and it really helped me lose weight and inches but now I cannot find it in ANY pharmacy store or discount stores such as Walgreen, WalMart, etc. Can anyone tell me where I can purchase more Alli??? Thanks in advance.


I found it at CVS behind the front counter (near the Nicorette). You have to ask the cashier to get it for you.

Your Namecathy ballenger

I have never tried the product. I am researching it. That is how I came across this site. The only place I have seen it on the shelves is Target.

Victoria (Editor)

Marylee (Verified User)

I have lost weight 5 times with Alli. This last time I have taken it for 18 mths straight, and I’ve lost 35 lbs and have gone from a sz 14 to an 8! I’m 5’1″ and now weigh 135 and only need to lose 10 more. It is slow but steady! I feel so much healthier. The less you weigh, the less you eat and the less you are hungry. I have hypothyroidism too so I know it works. I just turned 50 and couldn’t be happier with my body and life! I will take it forever if I need to! All I crave is salads & veggies now. I love Alli!


I have tried Alli twice, the first time after a year of bad health, went from 159 to128. This time I started at 149 and I am down to 137, less then 10 pounds to go. I am 53 years old and about 5’2″, I don’t experience horrible side effects because for the most part I eat low fat, in addition I walk 2 to 4 miles six days a week. Taking the Alli gives me that extra motivation I need and I too will take it forever if possible

  Very happy so far

I’ve taken it for almost a week… Very happy so far. It keeps you aware of what you are eating.

  Product is not worth it.

DO NOT TAKE THIS PILL!!!!! I experienced extreme hair thinning after using this pill for a little over 6 months. Definitely, definitely not worth it- I regret it every day! It is better to be a lil heavier, but with a gorgeous head of hair than thinner with dull, limp, thin hair. Normally, I don’t review stuff- but I feel like everyone needs to be warned… Do as u wish, but NOT worth it. (if u do take it- make SURE you take vitamins every day)


been on this years ago when it was not A over the counter.came across this and needed to comment on this statement.any change in diet can make you lose hair.its not this pill.your body will adjust to your diet,it takes time,I follow a lchf diet lost a lot of hair,wore hats for almost a year,till my body adjusted and vitamins started working.you need to do what you need to do,get healthy,exercise,talk to your Dr. I found what works for me,it was not this,but it was my fault I didn’t take my health serious at the time.im down 130 lbs in a yr. it’s possible.dont give up.if this is affordable and works for you.do it,everybody is different.

The hair loss is because the lack vitamins so just take your vitamins please.

  It works but expensive
Nye Stevens (Verified User)

I have been taking Alli for about two years and I have no complaints other than it is expensive and hard to find discounts. Costco the best. I am 70 years old and still have a full head of hair. Alli makes the fat pass through you and that of course appears in the toilet. That’s the point. Otherwise it goes to your waistline. Most of these websites are trying to get you to switch from Alli to some other and much less effective treatment.


I understand i have been taking it for a year now i was 330lb now 287 i love it


Do u work out while taking it?


I wouldn’t take anything especially while nursing without asking your doctor first

  Waste of money and not working
MunkieBone (Verified User)

DO NOT take Alli…it is the biggest waste of money ever…I took it for a month and lost 7 lbs in the first week great….then i couldn’t lose anymore and i was exercising an hour ever day and on an 1800 calorie diet….and I’m sure everyone experience the unpleasant stools…I ate about 15g of fat A DAY(recommended per meal) and still experienced that problem….now I am taking Lipofuze, I have been on it for less time so far than I was taking Alli and I have already lost more weight and you don’t have to worry about the unpleasant side effects like alli….and u don’t have to count ur fat intake only ur calories…..anyway good luck…i guess everyone is different but i know other people who were on the alli diet and they didn’t like it either

  Worth it but curious in hair loss

hhhhhmmmmmm, Have just started using Alli, but have had no Bm movements, and think I may have had over the recommended fat allowance. Although not much over. Very concerned about the hair loss people are talking about. Is it very common. Any way only early days, so fingers crossed!good luck to every one else:)

I have been on Alli since Jan 24th. I take it 3 times a day. I have been doing a bootcamp 3 days a week. I dont eat perfect, but I also dont eat fast food or drink soda. In these 2 months I have lost 13 pounds which is GREAT. I have never been able to loose weight. The only bad part is the orange oil in my BM’s but thats all. I will continue to stay on Alli and will post again in 2 months. I want to loose another 30 pounds. If you eat 3 meals a day, low in fat and workout. You WILL see results. If not, your doing something wrong. Your not looking at the fat in your food. Good Luck to all =0)

I have been reading up on Alli and am on the fence about taking it. I weight between 180-185 and cant seem to get past that 180 mark no matter what i do. I dont want to loose a lot maybe 10-15 lbs. I work out 6 days a week already and dont eat that bad. Any suggestions? Should i give it a try to see if it will be a jump start to my goal??


If your working out that much , you should be loosing weight along with building muscle . Are you meal prepping to help? 4 ounces of chicken or ground turkey , 1 cup of rice and 1 1/2 veggies? there is BCAA preworkout that helps along with fat burners that you can get from a nutrition shop

Victoria (Editor)

Hi Starrblue,
Taking Alli would help as a supplement to speed up your weight loss process. Keep in mind that everyone’s results will vary.


I have been on alli for a week. When going to the bathroom I notice orange greasy stuff. Is that normal?


I have been on and off Alli for the last few months. It made me constipated – I NEVER suffer from constipation. The oil that comes out is bright orange – can look like blood at first glance but is best described as the kind of oil you might get from bolognese sauce (fatty, orange). I haven’t noticed much weight loss so Im not sure I will carry on. I did have one episode of side effect and that put me off for life, I was at the supermarket and with no warning (I had not eaten ANY fatty food either bizarre) – luckily it was only oil and I was wearing dark blue skinny jeans – they are no longer with us as I could not bear to even wash them. I used to take them years ago and they definately worked but Im not sure now. Not sure they are worth the money or the worry about shitting myself!


It is if you’re exceeding the 15g fat per meal

  T I'm a little scared
yellow b (Verified User)

I’ve brought the product but I’m a little scared to use it. After reading the comments on this wall and people stating how they’ve suffered from bad stools to hair loss freaks me out. But I guess one way to find out if this product works is by using it. However what does worry me is going to work and having lunch only to run to the loo. Also my bmi is normal I wondered if were any major side effects to alli from having a normal bmi.



I’ve just bought Alli too and am also freaking out after reading this! I Know you might not be able to remember that far back but did it work? Was it okay? Thanks! x


As long as you follow the low fat diet and take multivitamins u dont have to worry as much about either symptom. the hair loss is primarily from vitamin deficiancy because the pill does make u lose some vitamins. The bm problem is because of too much fat and ur body adjusting to the product.

  Super morbidly obese
Anonymous (Verified User)

I was super morbidly obese when I decided to try Alli I knew I needed something to motivate me and a quick weight loss would do this. It is now 11 months later and I took Alli for 6 of those months and I have lost 120lbs. I haven’t noticed hair loss and only experience side effects if I go over the recommended fat amount. I couldn’t recommend it highly enough. I realise alot of my weight loss is down to a healthier diet and excercise but Alli made me more conscious of this and helped to speed up the process. I am delighted and would recommend it to anyone thinking about it.


I love it. It worked well for me then they took it off the shelf. Is it back on the shelf at Walmart?


This has been my third day taking it. I haven’t experienced any bm so far. How long does it take the pill to kick on?


Yes its back but I bought mine from Amazon

I have been using Alli since August 17 of this year and have lost 1.5 lbs. Then this week I checked in and gained it back. I am eating healthier, no sweets, etc and can’t understand why I gained what I lost using this product. I am glad it worked for some, but disappointed it has not worked for me. It’s very expensive and I am finishing up my last bottle. I am looking for advise of a diet program that “really” works. Alli is just not worth the money and time spent on their web based lessons. If anyone can offer advise on which product to use, I would really appreciate it. I have 20lbs to lose.

  I would not recommend alli to anyone.
Ashley Weigel (Verified User)

I took alli last year after the advice of my doctor. I took it for about 5 months but had to stop because I was having really bad back pain in my right side. I will say that it did work, and I lost almost 20 pounds, but it was not worth the pain. Here I am, almost exactly one year later and I’m having to get my gallbladder out! I never, ever had any problems with my gallbladder before I took alli and I feel like taking that drug caused my gallbladder to malfunction. I’ve been battling the back pain for a year on and off, and my primary care physician always misdiagnosed it as UTI’s or kidney infections. I finally went to a brand new doctor 2 weeks ago, and he found the problem almost immediately. I’m just curious how many other people have experienced gallbladder problems after taking alli? Before taking alli, I was overweight (5’5” and 178 lbs) but otherwise healthy and never had any major health problems. I would not recommend alli to anyone and I’m just looking for someone with a similar experience. I don’t want to be carried away, but I feel like there should be a lawsuit or the like publicized to make people aware who are thinking of taking this drug. Please respond if you, or anyone you know, has had gallbladder problems after taking alli.


I too had to have my gallbladder out while taking Alli. I thought I was having a heart attack! They had me in emergency surgery that night to remove my gallbladder and ended up in the hospital for 5 days. I’m sad that it’s happened to others but it’s nice to know I was not the way not one.


I took Alli for little over a week. I lost 1 pound but suffered from severe pain in my lower back and in my left side radiating down my left leg. I pray I don’t have any damage to my spleen, pancreas, or kidney!!! Personally, I would not recommend taking this drug.


had to have my gallbladder out also. I don’t know if it was related to alli or not. I had a 1 inch stone and this summer has some bad back pain that radiated to the front. They advised me to have it removed. I had been taking alli for a year and lost 50 lbs. I have gained weight again so I am going to try it again. Hopefully it won’t cause anymore problems since I don’t have a gallbladder


Hi Ashley,

I read your post.. I have taken Alli on and off but didn’t experience any back pain..I wanted to start again but after reading your post I am scared.

  it does help in some ways.
current user (Verified User)

I’ve taken alli over the past 1 1/2 yrs. Granted it hasn’t been every day and I’ve only used about 2 bottles. But it does help in some ways. I’m also on Weight Watchers and have lost 70 lbs so far. There can be a few side effects but I’ve never experience anything embarrassing. It has caused some low iron levels. It really helps when you have to go out to eat (say when traveling for work). There are times no matter how hard you try you cannot stay on a low fat diet. I have noticed I will lose an extra 1 or 2 per week by using the product compared to not using it. But I try not to become dependent on it. It is a nice thought to eat all the fatty foods I want with no consequences. But if that was the case I wouldn’t have lost 70 lbs so far. My advice – try eating less, lower fat and less sugar and also exercise every day. If you need a little boost, then try alli. But don’t expect alli to do it all for you. It is no magic pill.

I love Alli. I have been on it for a couple of months and lost 17 pounds. Yes, you do to be honest, have oily stools if you aren’t eating correctly. When you first start it, give yourself a couple of weeks for your body to adjust. Stick close to a bathroom and I always wore a panty liner to avoid any embarrassing accidents. This really gives you the motivation to eat right and to keep dieting. It also gives you the luxury of splurging every once in awhile.

My mother is on all kinds of meds(high blood pressure, breathing issues, high everything alomost) and she’s fine.

Been taking Alli for 12 days, love the results. Already people are asking what am I doing to lose weight. Yes I have had the famous bathroom results OMG! and thanks goodness for pantyliners
but bathroom results are like a spank for the hand, telling not to eat the wrongs foods, well it taught me, eat right or its to the bathroom.( But most of the time I exercise) I was doing that before Alli, but now I am seeing results. Advice take vitamin at night.
Alli may not effect every single person the same, everyone has a different body chemistry. But most results seem similar.

Sarah (Verified User)

Interestingly enough…I thought I would try Alli and also test it out as in “let’s see these horrible side effects.” I took my three daily doses of Alli all with fatty meals (pizza and stir fry). Absolutely nothing happened. I expected to be running to the bathroom constantly. Like I said, nothing. I am beginning to wonder what all the hoopla is about and whether Alli itself is a farse.

  Can loose weight with it?

I am 5’10 and 165lbs. I am thinking about taking alli but I’m not sure if it it is worth it/it will help me lose about 10-20 pounds. Do you think alli will help?

  Does Alli thicken the blood

I am taking 2.0 mg of Warfarin, does Alli thicken the blood. My last reading was 1.9 and they want it between 2 – 3.



The key is to let your health care provider that is monitoring your INR know you are taking Alli. Alli interferes with the absorption of fat-soluable vitamins (one being vitamin k). The key with warfarin is if there are changes in meds or diet, you need to let them know. They can adjust your dose accordingly. Of course, you may need to have more frequent INR’s drawn until it levels out. Also, like with the multi-vitamin, your warfarin should be taken at night or 2 hours or more after Alli was taken. You can research it online as well.


I don’t think you are meant to take Alli if you are already taking Warfarin. However I don’t know why, or how it affects your blood. I’d recommend asking your doctor.

  Can loose weight with it?

I am 118 and 5 foot 2, but when I had my fat percentage measured, it was high (27%). I am interested in losing some of the fat, even though technically my BMI is still normal. I exercise a lot and eat pretty well. Do you think Alli would be helpful for me- I am interested if anyone else who as in my situation tried Alli, and what they thought. Also, I am generally constipated, so Im hoping Alli might even help with that issue too.
Any comments?

Victoria (Editor)

Hi Michal,
From your weight and height it does not seem like Alli is what you need. That’s actually a normal and healthy weight to have at that height. Eating right and exercising regularly would work best for you.


the alli pill will most likely be a waste of money for you. it only really works with people who are obsest or boarderline.My sister is 115 and it didnt help her at all. If you have problem with constipation take dietary fiber supplements that you can get at like Walgreens of CVS. It helped me regulate (every day or every other day, i was going every couple of days) and avoid constipation

do you have to eat healthy to loose weight while takin alli

Victoria (Editor)

Hi Ashley,
Yes, it is recommended that you eat healthier and exercise regularly. Alli is designed to block fat storage of food that is consumed up to 25% so eating fatty foods regularly will not work well.

  Confused wth some posting.

I am currently only about 20-25 pounds above where I’d like to be. Is Alli a good option for me? I’ve read a couple of conflicting posts… Thanks!


Definitely give it a try – husband and I both had 2 stone to lose and at just a month in we have both lost a stone – he takes 1 tablet at dinner time I take 1 morning 1 evening. We have had no side effects but have changed to low fat diet but have alcohol and a treat at weekend – Alli has really fitted in with our lifestyle and we are both confident of losing that 2nd stone soon – good luck


did you exercise or just eat healthy?


Exercise!!!! Me!!!! Nah!! Think im living it up if I turn the TV over without the remote!!! Seriously though I do have dogs I walk but thats the extent of my exercise and I have an office job so sit down all day. The low fat diet has been the key really for us and we are both still losing and very positive about the whole thing –

I’m not an expert, but with the knowledge I do have about weight loss, I believe you’ve actually stalled your metabolism and any chance of losing weight. Any program under 1200 calories per day will literally send your body into starvation, and it will cling to any fat reserves you have. Because of the 2 hours of exercise you’re getting each day, your caloric number is likely higher. Your best bet is to make an appointment with a nutritionist or a personal trainer, as they can tell you exactly what you need to eat to let your body know it’s safe to get rid of those fat stores. That situation sounds like one that would make any woman desperate, but your body doesn’t see your plan as a reason for it to lose the weight, but as a reason to hold onto it with all its might. I HIGHLY recommend clean eating diets if that helps guide you in any way to a solution, and talk to your doctor about pairing Alli with whatever program you decide on (the website might have more specifics about drug interactions).

I am on day 3. Lost 3lbs in the first 2 days! I am 40 years old and have tried everything. I know that I need something that will work right away, so that I am motivated to stay with it. I am sure that the changes in food choice is the main factor here, but I think Alli is helping since I did not eat that badlt in the first place. The only other diet that worked that quickly was Atkins, and wow was that hard to stick with after a couple weeks! I think that the threat of an “accident” is motivational as well, and I could not come up with a better one! I have had no problems yet. I felt a little tummy gurgling on day 1. My plan is to get off the weight that I need to, for better health, and then use Alli as needed for maintenance. I have not been exercising for quite awhile, but with the first few lbs down, I feel like bellydancing again! (I still have 31 lbs to go…..and I will check back in soon!)

  Going to start using.

OK, is it the low fat diet that is doing the work–or Alli. Sounds like Alli is the threat of punishment (uncontrolled bowels) that keep you on the straight and narrow. I’ve bought it, I’ll try it. But a low fat diet will automatically make you lose weight. If it takes the “paddle” of Alli to make us stay on the low-fat diet, I guess so be it. Wiah us beginners luck.


I was thinking the same thing. If you eat virtually no fat, you’ll lose the weight, so what’s the point in taking the pill? To keep you on “track?”

  Going to start the product.

I weight at 251 I started at 261 but i was on the ankins diet counting carbs. i am going to try alli first pill wil be on sunday with my two daughters i hope the poo that you all talk about is ok because i have trouble already and its not going like i should so hope it will help me go as it has a lot to do with weight lose,will let you no good luck to all of you already on the alli.

Alli doesn’t effect alcohol.

40 year old male here who has been using ALLI for all of two weeks. Have read all the horror stories about “treatment” affects so was pretty prepared. I weigh 189 and just cant seem to get past 185, my goal is 170. After 2 weeks, weight is down to 182 and its been so easy. I did have an oily BM but only once and of course it was when my meal was pretty high in fat. I watch my fat intake so its not a problem any more. Alli does seem to work very well. Follow the directions, no more then 15 fat grams and you will see results.

Starting the low-fat diet is very highly recommended before taking Alli. I have been on the low-fat diet for 1 week now, lost 4lbs, I will start Alli tomorrow night and let everyone know what happens in another week! I am so excited… and take going to take the multi-vits so I can keep my hair!

will alli make me want to eat less with dieting?

Victoria (Editor)

Hi Shunikka,
Alli is designed to block fat storage in your body while you eat. It should not make you less hungry but we do recommend that you maintain a healthy diet.


It will make you want to eat less unhealthy foods when you experience the treatment effects.

I started taking Alli with just a slightly healthier diet, as my plan to was transition over a period of a few weeks just as I did when I have up all sodas – because I failed many times before by just giving them up cold turkey, but on night 3 I experienced my first treatment effects and the next morning I immediately changed my diet so I was consuming even fewer calories, less fat, etc. The effects shouldn’t make you want to stop taking Alli, they should make you want to change your diet – I’m going to continue taking Alli because thinking about the effects really helps me out when I’m otherwise lacking the will power to avoid certain unhealthy foods.

I was an idiot and took my sisters pill when i was younger.. just assuming it wouldn’t actually make anything happen like the other diet pills, and ate maybe 6 fried jalopeno poppers. I was fine for a few hours and then i just started violently throwing up and having to go to the bathroom at the same time. If you had A LOT of fat I would understand that to be the reason you got sick.


I read that some people are allergic to certain ingredients. If it continues I would discontinue use of Alli.


The first pill I took I was very sick to my stomach. I thought it was a coincidence, so I waited a day and started over the next day and I feel awful again. I guess it isn’t for me…bummer


I took for the first time last night too and I was also violently sick in the middle of the night. Couldn’t sleep and vomited twice. I didn’t have a dinner high in fat, either. I’m going to call my Dr. before I try again.


maybe you are pregnant and don’t know it because i never gotten sick or had any head aches thats why they tell you to ask a dcter before taking any weight loss pill.


Must be a coincidence. Alli will not make you ill.

Has anyone heard anything about this causing liver dammage?

Victoria (Editor)

Hi Barbara,
Liver damage should not be a side effect of Alli. However, if you feel like you’re experiencing damage to your liver you should stop taking Alli as a precaution and consult with your physician to see what may be wrong.


I used xenical when it first came out. I lost 50 pounds in 6 months and kept it off for 10 years. I now have some chronic health issues and have gained about 20 back. My Dr. has ok’d me to use alli and I have been for about 1 month. Weight loss seems slower, but I am older and alli is only 1/2 of what the xenical was. Watch your fat intake and you will be fine. Alli is nice because the side effects are way less too. I loved xenical and so far so good with the alli.

Hey has anyone drank Alcohol while taking Alli? I’m thinking just a glass of wine or 2 on the weekend….Let me know…I don’t want to have a PROBLEM…if you know what I mean..


I drink miller 64, has no fat in it. You need to check the fat in what you want to drink


When it comes to acohol most of them are okay to drink. stay away from white russians and milky or really high sugary drinks and if you drink mix drinks, pick diet sodas. light beer and white wines are recommended when on the pills.

sandy (Verified User)

i just started taking alli and have had only one accident.My question is i only eat one meal a day. I dont get breakfast or lunch, but i sometime snack. I have been taking one pill aday just before dinner, and its working. Im wanting to lose 20lb. do you see a problem with just taking one pill aday? will it still work?


I’m the same way. I was anorexic when I was younger, and since then my eating habits and metabolism went crazy. From eating just the one meal a day for years, my body recognizes myself as being in a somewhat “anorexic state” and whenever I eat that one meal, it latches onto all the calories like crazy, making weight loss hard and weight gain easy. This is part of the reason why I started the Alli, because I had to figure out a way to not give my body all of those calories it was latching onto. However, even the doctor told me that while on it, I had to work on eating more during the day. On Alli or not, eating like that is unhealthy and in the end your body will never EVER be in good condition.


Hey there! It is suggested to eat around 5 small meals a day. Once again the most important meal IS breakfast. If you are going to have 1 big meal a day… make it breakfast. Also snacking is OK as long as it is healthy snacks AND you are sure the snacks do not interfere with your small meals a day. Akki suggests 3 pills a day, you should obey these UNLESS your body is still adjusting! 🙂 best of luck!


I think you should be having more then one meal a day!


I think you should be having more meals in your day!


your suppose to eat three meals a day you have probably already heard this but breakfast is the most important meal of the day if you do that and cut out the snacks i dont know why alli wouldnt work for you.xxxxxxxxxxxxx

I weighed 160.7 when I began taking Alli. I have beee on it for three weeks. I work out and burn approximately 6,000 calories per week, despite closely monitoring the 1200 calroies per day, I have lost almost no weight. I am staying very much within the guidelines and have not had the bouts of greasy gas and stool, so I know I have done well by their plan. I think that if you are not significantly overweight and have to actually ADD fat to your diet in order to meet their suggested minumums, you will not have a successful weight loss process with Alli. After three weeks and a loss of only 4lbs (and given my exhaustive work, this is paltry compared to where I would be on a strict 1200 calorie/ 20 grams of fat diet. I am disappointed.

MC in WA

You may not be seeing a loss in your actual weight because of gaining muscle mass. Your body will build mass quickly if you’re working out religiously, and that’s a good thing. 🙂


Hi Ann,
Don’t give up! Because you are not as heavy as some Alli users, your body does not drop weight as quickly. 4 pounds in 3 weeks is awesome! 1-2 pounds a week is really healthy weight loss at your current size, and you’re right on with those numbers (: At 160, if you want to lose 30 pounds, total guess, you can get there by summer. Great work!!!


Alli is ONLY for people who are overweight. If you fall in the overweight, obese, and ect categories then Alli can help you. But if you are in the normal range of weight and just want to “slim down”, then Alli was not made for you. Read the brochure, it states that clearly. Also, your body will not let you lose weight easily if you are in the healthy range.


Yea alli is really only for people who have about 100lbs to lose. At your weight you really dont need a weight lose pill to get the results you want. Make sure you shock your muscles same work out every day will make your body plateau, and weight lost will be slow. Since you’re almost at your weight you need to be losing it is slower then a fatter person who has a crap ton to lose. Yes hun this will take sometime, but dont give up just be happy you dont have another 100lbs to lose. 😛 I started out 295 i am now 245. I have a while to go, but i dont give up =) good luck Ann and hopefully you can lose the bit of weight holding you back from your perfect body

I’ve lost in total 50lbs since November. Yes i am not lying. 😛 It’s weird when you hear peoples achievements, but finally i can show my friends that you can lose it =) Living proof. Listen to me with working out and eatting right this honestly does work, but if you have no idea what the calories are you burn how the hell will you know what to eat.Check out the bodybugg. My boyfriend and i did, and even when i reach my goal of 150 I will still use that wonder machine to check how many chips and sodas i can scarf down with out gaining that day 😛
Best of luck to everyone out there, and keep up the good work.

leslie (Verified User)

I have been taking alli for about 3 weeks. I have only had “treatment effects” once, and I’m still trying to figure out what I ate that put me over the fat limit. I love this product though! It makes me constantly aware of what I am putting in my mouth. I have lost 13 lbs and and my body feels 100% better without all the fat I normally eat. I have so much more energy! The key is to follow the directions EXACTLY: no more than 15g fat per meal and skip the pill if you anticipate more. Good luck to you!


I agree Leslie, The key is to follow the directions EXACTLY: no more than 15g fat per meal and skip the pill if you anticipate more. This is an entirely true statement. I am not grossly overweight but truly have problems from stopping those 10 lbs of weight fluctuation I have always experienced. Being a woman, I have had problems with constipation and honestly, the more “relaxed” production of stool is a lot more manageable then the uncomfortableness and pain associated with constipation. I do seem to get gassy if I eat salad dressing that is not fat free, or if I use a lot of sugar in my drinks. To solve this I simply changed to all fat free dressings and changed to Trivia for a sugar substitute and all’s well now. I truly feel people that are having the “oily discharge” effect, possibly are purging their systems of latent fatty residues, or they are simply not realizing they are consuming as many fat grams as they are. I used the diary, and I feel it really helped make me aware of what I am putting in my body. The food diary is just a helpful tool to keep u on track. Therefore, people I believe if you follow, the 15g of fat per meal rule you should have no other problems. In addition, I do feel much better than I have in a long time I hope this is another treatment side effect. Good luck all.


Have you lost weight? I need to lose 10-12 lbs and wonder if Alli will work for me. I exercise 4-5 times/week and maintain a healthy diet most of the time. However, I’m 50 and it’s tough to maintain. I need help and want safe alternatives

Victoria (Editor)

Hi Lili,
No, Alli should not be taken while pregnant or breastfeeding.


Absolutely NOT safe to take while breastfeeding. The baby’s brain is very vulnerable to the right amount/type of fats–which is found in breast milk. Kudos for nursing—do your weight loss naturally, diet and exercise, until baby is weaned. And don’t wean baby early because of body concerns.


please don’t. it will harm your baby 🙁


You shouldnt use alli while pregnant or breast feeding. You loose your water soluable vitamins in the loose stool. The baby get your breast milk which is mostly fat and then alli also in the milk it will cause the baby the have diarrhea and vit def. It can also cause preg or nursing moms to have low potassium levels which can caouse heart arrthmias. So unless you are healthy dont take this medication.

Are there other side effects?

you may take alli during your meal or up to one hour after eating it however the sooner the better so maybe up to 30 minutes after taking the pill.Does anybody read the material before taking anything anymore?


Margaret, for one meal, you should be having UNDER 19 g fat. If you are doing anything above that then you are much of the reason for your oil. The only time I had oily anything on Alli was when I was eating too much fat and that sounds like your issue. You are having treatment effects because you are not following the diet strictly. That means measuring and counting EVERYTHING ! Including the calories in what you cook with ( oil, butter, ect) and using the correct servings.

Dunno about anything coming out “greasy”, but the only time I get gas is when I hold back my b.m. (to be expected). I knew when I had to “go”, and made the commitment to not ignore it, so I haven’t had any embarrasing times. Know that the object is to push the fatty stuff thru fast, but because of the push, the nutrients aren’t absorbed, either. The medical questions asked before need a dtr’s attn, but I have changed ALL my meds to the evening where the Alli won’t be pushing their effectiveness out, too!

skm (Verified User)

I have used alli for over a year now. You do not have the greasy bm and gas every day unless your diet is made up of a lot of fat. I have experienced no hair loss as stated by Nikki.

The best thing is that you learn what foods are high in fat and you begin to eat healthier.


my experience was exactly like nikki’s. it took me a long time to realize what was causing it and it was so bad i could not go out on the street without a wig. within four days of stopping, the problem ceased. i had been taking vits-mins all the time. i guess if that is your weak spot, alli will cause the problem.


ok people with hair loss and say they are taking the vitamins are you taking them two hours prior to taking alli or several hours after taking your dose of alli. it does make a difference because alli is a lipase inhibitors to it stops 25 to 30 percent of your fat intake from even being absorbed by your body to include the vitamins that are absorbed by fat. so if you want the multivitamin to work you should take it two hours BEFORE taking alli or several hours after.


How much weight have you lost in the year?

Hi Beverly,
Every person’s body will react differently. We recommend for you to speak with your physician before taking Alli.

what is to happen when you stop taking it?

i wanted to try alli but i feel that i just dont know enough. what is to happen when you stop taking it. the changes with the bowel movements are also discouraging any suggestions

Victoria (Editor)

Hi Elizabeth, once you achieve the results you’re looking for, its okay to stop taking the product. The bowel movements changes is a common side-effect, please refer to your physician if this happens to you.


When you stop taking it, you will gain weight if you haven’t changed your eating habits while on it. But that’s the point, you are supposed to change your lifestyle (like with any diet) so that when you are the way you want, you will be fine. As for the bowel movements, yeah it can be a pain and it can be gross, but it is a small price to pay if you want that little extra kick. Some people don’t experience them at all. I never once experienced anything gross with my bowels while on it, and a lot of that was due to the fact that I was doing the right thing with my diet. If you go out and purposely eat greasy foods that you aren’t supposed to be eating then, well, yeah chances are you aren’t going to be happy with your bathroom experience after that haha.

i want to try alli, any suggestion?

wear a pantyliner, really make sure you watch what type of fats you eat. You don’t need to add kcaloric heavy foods (sour cream on your potato) you will only regret it latter. Try it on a weekend when you know you won’t be seeing anyone. Oh and most people forget to drink water. And get in more plant fiber.

This is the third day, and first time I noticed “treatment effects” but nothing unmanageable. Best part is the awareness of a healthy caloric intake and fat grams per meal. It motivates you to follow this diet plan to make the money worthwhile! So far, eating under 1400 cal/day and have lost a pound a day. Yay!

I am eating healy(salad,cheerios, and meat) yet I still have greasy stool


maybe the type of meat try just chicken,fish turkey


look how much grams of fat are you eatting? you do realize you can only have, about two TABLESPOONS of dressing before you hit the 15 gram of fat mark. And red meat is fatty, try eatting some roasted nuts instead.


how much salad dressing are you using?

  I was having hair loss. No other side effects so far

Took only one pill last night and already noticed that I was having hair loss. No other side effects so far but I have thin hair to begin with and was not comfortable with the amount of hair loss I experienced with just 1 pill!


For me, i got a multivitamin and take it before bed. I weugh almost 300 pounds. So what would i rather be, thinning or obese. Ill chose thinning.

My daughter who is 18, wanted to get on the pill so I purchased it for her and she was taking the pill, following a healthy diet & exercising. She became anemic, & weak, even with taking her vitamins nightly. Advised to stop taking them which she did.


your experience is not impossible. i know this firsthand, but have difficulty getting this comment accepted because i keep getting the message “duplicate comment,” so this is all i can say, but this problem is not caused by lack of nutritional supplements, because i took them all the while i took alli. you can actually feel the fallout and then find the evidence on the floor.


you are absolutely right. i too have thin hair and the longer i used alli the more my hair fell out until i was afraid i’d end up bald. i finally, through the process of elimination, traced it to alli. i think that if one has the tendency toward thin hair, this will finish the job. just before i tried stopping alli i was so balding i thought i’d have to purchase wigs. in the three days since I stopped alli, my fallout has decreased dramatically.


I have taken Alli for two months and just started noticing hair breaking and my hair stylist said the shine was gone and noticed other breakage and thining. She swore me to stop taking Alli! I threw it away as soon as I got home…I was totally freaked out as that was the only change I have done.


I am 5’2 166lbs and need to get to 135. Do you think alli will work for me?


I used Alli last year and it worked,I lost 23 lbs in 3 months. I stopped take the pills but continued to stay on the low fat diet after my weight loss. I did not take my multivitamin daily as I should have and experienced a dramatic hair loss. Not Alli’s fault, totally my own. If you are going to take it be certain to take your vitamin.


O boy I used ally four years ago. Went from 170 to 117 in around five months. I was very happy. I did not take the vitamins after I stop taking allI my ha. Fell so much that I was I deprecion and I never realized that it was because did not take the vivitamin.




NO it is not… I am taking alli with weight watchers which as been effective in helping me lose my last few pounds, but weight watchers works AMAZINGLY with no bad side effects. I wouldnt be using alli if i didnt need extra help losing the last 5 pounds.


@MILLIE1CMR – I have done almost every diet out there. Weight watchers is the one that gives long lasting results. It is not a quick fix but it works!! ALLI is a pill/supplement Weight watchers is about changing lifestyle. you can do it!!


Hi I read your comment about the need for multivitamins when taking Alli. I also didn’t take a multivitamin and my hair is falling out rapidly. It’s a bit scarey – would you mind telling me if yours returned to normal quickly please.


Last week I was crying in my kitchen because my hair is thinning out and I didn’t know why. Alli is the only big change and I am bummed because I had NO other bad symptoms. I wasn’t taking multi vitamin though. And now I am taking the vitamin but scared to take Alli. I have almost a whole bottle of it!


thanks because i have been taking alli for two weeks and just took my first vitamin yesterday


maybe you were experiencing hair loss before you took the pill. And just noticed it afterwards. I don’t think that could happen only after 1 pill… :)not trying to be mean or rude… just common sense..


Impossible to have hairloss from only one tablet. Anyway hairloss is a symptom after dieting very strictly for a long time. In fact what happens is when you restrict your diet your hair stops falling out and when you resume eating again the hair you were due to lose anyway falls out over a week or so, thus seeming like hairloss…No worries necessary
