Alli Review - 19 Things You Need to Know

FDA-approved Alli’s only ingredient is the fat-burning orlistat, which has been around for more than a decade. The company claims it is a clinically-proven way to lose up to 5-10% of body weight, but is it safe? We were concerned when we found a long list of side effects attached to it.

Our crew is hesitant to recommend a drug that could cause anything from rashes to back pain to bowel leakage. We investigated every aspect of Alli, examining if the pros outweigh the cons. We provide you with a summary of our conclusions.

Alli can be purchased through their Official Site.

Overview

What is Alli?

Alli is an over-the-counter weight loss supplement that contains 60 mg of the prescription drug orlistat. This medication is designed to assist individuals in losing weight by preventing the body from absorbing all of the fat found in food. Unlike a magical solution, Alli is not a quick fix for shedding pounds but rather a supportive tool when combined with a healthy diet and regular exercise.

When you take Alli with meals, it works by reducing the amount of fat your body absorbs, leading to a decrease in calorie intake and, subsequently, weight loss. It is important to note that while the manufacturer claims that Alli can help dieters lose up to 50% more weight than diet and exercise alone, the results may take about two months to become noticeable.

Alli is FDA-approved and targets fat deposits in the body, complementing your existing weight-loss efforts. However, it’s crucial to understand that this is not a miraculous solution; it won’t cause rapid weight loss. Instead, it is recommended for individuals 18 and older who are already following a low-calorie diet and are overweight or obese.

It’s worth mentioning that Alli is the 60-milligram, over-the-counter version of the prescription drug Xenical, which contains 120 milligrams of orlistat. Both Alli and Xenical are intended to be used as part of a comprehensive weight-loss plan that includes a low-calorie, low-fat diet, and regular physical activity.

Orlistat, the active ingredient in both Alli and Xenical, is available over the counter as a weight management aid. Xenical, with a higher dosage of orlistat, tends to show results faster when combined with a reduced-calorie diet and regular exercise. It’s important to differentiate between the two: Orlistat is the drug, while Xenical is a branded version, and the generic form of the prescription drug Xenical is marketed as Orlistat.

What does science have to say about this clinically-studied weight-loss pill?

  • Nutrition & Metabolism – It looks like Alli may work best when taken with flaxseed fiber and calcium. As a matter of fact, research shows an increase in fecal fat excretion of about 100% when these two supplements are added.
  • PLOS Medicine – In one review of research, authors suggest “Reports of [Orlistat] trials seemed to have systematically understated adverse events.”
  • BMC Obesity – And while Alli may, in fact, promote weight loss, it may not be the most effective product on the market.

Ingredients

Alli Ingredients

The only active ingredient in Alli OTC is:

  • Orlistat

This ingredient is responsible for its fat-blocking properties. It does this by blocking the fat-breaking enzymes in the body. The body does not absorb fat that it does not break down and it thus eliminates it.

The rest of the ingredients are inactive, contributing to the appearance, stability, and taste of the weight loss supplement.

Benefits

Alli Benefits

There are health benefits of using Alli. Some of the benefits include:

Fat-Blocking

Alli claims to block small amounts of fat from the body by absorbing them.

Easy to Use

According to the packaging, you can take Alli up to three times a day with appropriate meals.

Enzyme-Blocking

It may block the enzymes that cause weight gain (see research in Diabetes, Metabolic Syndrome and Obesity).

Is It Safe?

Is Alli Safe?

The FDA approved it for use by people over 18 years of age. It is best to have a BMI of at least 25 when taking Alli. Blocking fat in underweight individuals can be dangerous and can cause serious health problems.

Check with a doctor before using Alli if you are on any other medications, especially medications for weight loss.

Alli’s ingredients are simple and clinical proof supports them. Follow the instructions accordingly and never share the medication with anyone who may not need it.

What Does It Do?

What Does Alli Do?

It can help dieters lose up to 50% more weight than dieting and exercise alone.

It does this by blocking a portion of the fat in food eaten. They recommend users do not eat more than 5 g of fat per meal when using Alli.

With fat-containing ten calories per gram, this can result in significant calorie reductions.

Alli functions by interrupting fat digestion and blocking 30% of the fat users consume, leading to calorie reduction.

Does It Work?

Does Alli Work?

When used correctly, it can help dieters lose an additional pound for every two pounds they lose on their own. It would help if you only took it with low-fat meals. It is not a “miracle pill,” allowing dieters to eat whatever they like and still lose weight.

By following a low-calorie, low-fat diet and exercise plan, and adding Alli, it could work. Although it can help you lose weight over time, it is important to remember that it is usually not significant.

It would help if you used it in conjunction with a diet fitting within your weight loss goals and an effective exercise program.

It is also essential to drink at least eight glasses of water per day.

Side Effects

Alli Side Effects

Some people who use it report side effects. Loose, watery, and oily stools are one of the more common complaints.

On the official website, Alli warns of potential gastrointestinal related side effects. These effects should only occur when first starting use, though.

According to LiverTox, additional side effects from its ingredients may include:

  • Poor bowel control
  • Dehydration
  • Vomiting
  • Nausea
  • Skin rash
  • Back pain
  • Weakness
  • Dark urine
  • Flu-like symptoms
  • Clay-colored stools
  • Itching
  • Loss of appetite
  • Sore throat

The undigested fat deposits typically appear in stools in fatty deposits that can be orange and oily, states the Indian Journal of Endocrinology and Metabolism. Many dieters report finding this oil staining their underwear and clothes. Overall, it can be a messy experience to use Alli, and this is more likely when you take it combined with a high-fat meal.

There is also an extreme sense of urgency to defecate when using Alli. They suggest that, if you are using Alli away from home, you bring an extra change of clothes with you for this reason.

Some people also report an increased number of bowel movements during the day. This is due to undigested fat moving through the digestive system.

If you experience any of the other above side effects, stop using Alli, and consult your doctor.

This supplement comes with some side effects related to digestion and nutrient deficiencies. It could also interact badly with some types of medication.

The company claims that the best dose is 120 mg, three times daily.

Reviews

What About Alli Reviews?

There are many weight loss reviews for this product. To get an idea of what consumers are saying about it, we will examine some of the reviews that actual users posted.

Many of the positive reviews state that users had lost weight when they used it correctly. These users say that they are satisfied with the product and suitable for short-term use with a low-fat diet and exercise.

But there are some negative reviews online as well. Some people state the adverse side effects as the reason why they would not purchase Alli again. Some users reported severe nausea, vomiting, and gastrointestinal issues when taking the product.

Another reason for negative reviews is the cost. Many consumers feel that Alli is too expensive for the results they got when using the product.

The reviews are mixed and can be somewhat unfair since many people are misusing the product, such as taking it with fatty meals then reporting unwanted side effects.

These side effects don’t usually happen when you take it with meals containing less than 15 grams of fat.

Directions

Alli Directions

According to the packaging:

  • You can take the product up to three times per day with a full glass of water before a meal containing no more than 30% fat.
  • You can also take it up to one hour after eating, and it would still be useful.
  • Women who are pregnant or breastfeeding should not use this product. Only dieters who are 18 years of age or older and not underweight should use it.
Results

Alli Results

Many people report satisfactory results when using weight loss pills and diet or nutritional programs such as Weight Watchers or Nutrisystem.

It is best for short-term use only, and people report that it loses its effectiveness after about six months.

 

Alli and Weight Loss

Weight Loss

Alli and Weight Loss

The weight loss with Alli will not be significant. Dieters report only losing a few pounds more than with diet and exercise.

Typically, many people lose about 7 lbs in six months. However, it is only suitable for short-term use and will not produce significant weight loss. The cost may outweigh the benefits. Its results are positive but minimal.

According to the Journal of Obesity, consuming Orlistat over a 6-month period could cause some weight loss and improvements in the diet. More research published in Vascular Health and Risk Management found that Orlistat could cause a small, but still statistically significant weight loss.

However, ClinicoEconomics and Outcomes Research found that this ingredient may not benefit public health. Additionally, Archives of Pharmacal Research research found that the use of this compound may lead to some gastrointestinal distress.

If someone has a small amount of weight to lose, and they are willing to persevere with the side effects, Alli capsules can be beneficial. However, it will not suppress appetite or increase metabolism.

For those who eat occasional high calorie, fatty meals, Alli is not useful. However, it may be an excellent choice for the dieters who can stick to a healthy meal plan to help them lose more weight than dieting alone.

Alli also offers online resources to users to help them with their weight-loss goals. When you make an account on their website, you can access healthy recipes, meal planners and trackers, food reports, and weight trackers. It is unknown whether you need to buy the product before receiving these resources.

What Users Are Saying

What Users Are Saying

“This is an FDA approved product. If you take it for all meals, you will have a loose stool. I recommend using it for lunch and dinner, the larger meals of the day. It has helped me control my weight. I also take Irwin Carb Blocker.”

“I used this several years ago and noticed the difference. You could see the fat in your stool that was not absorbed. This recent bottles are not doing anything. I can tell by the way I feel and from my poo. For $80 this is crap, pun intended.”

“I’m a 26 yr old female, 5’8 114lbs, using this for curbing appetite & energy.

REVIEW:
The Good
I like the flavor a lot; I don’t think it’s too strong or too artificial tasting.
It really does curb appetite, I’m not hungry at all while I’m drinking this during the day. It takes care of my sugar cravings (which are severe, I could eat spoonfuls of sugar and want more, lol)
It gives me energy because of the caffeine. It seems to have a much stronger kick than regular coffee, even compared to my 4 shot espresso drink.

The Bad
Very similar to other drinks with very high caffeine content, I kind of feel like I’m addicted to it, haha. I wake up feeling like I need it. You’re not supposed to drink it 5 hours before bedtime and I want to drink it all day and night long.
I do start having sugar cravings again in the evening so there is somewhat of a ”crash,” which seems somewhat counterproductive.

The reason I didn’t rate this 4 or 5 stars is because of the “crash.”

As an important side note about the directions:
The box says to take 2 servings in the morning and 2 in the afternoon each in a 16.9oz (standard size) water bottle… that’s 4 packets a day!
For reference, each packet contains the equivalent caffeine content of 1.5 cups of coffee. 6 cups of coffee is WAY too much for me so here is what I DO:
I mix 2 packets in a 32oz bottle (empty Gatorade works well) with a handful of ice and drink it in the morning/through the afternoon.”

Bottom Line

The Bottom Line on Alli

We like that the FDA approved Alli and that research proves the effectiveness of Orlistat. One of the main concerns related to side effects from Alli. Bowel leakage is an incredibly embarrassing situation, and we’re not sure it’s worth it when there are other available options.

We are in full support of living a healthier life, and we also know that means being at your healthy weight. Sometimes, the changes that are needed are difficult, but they don’t have to be with a clinically-proven system in place.

One of the best weight-loss apps we have seen is one called Noom. With personalized meal plans, human coaching, and extensive food logging, and more, Noom makes it easy to make healthier choices, lose weight, and understand your own eating habits.

Alli

Q:
What is Alli?
A:

Alli is a weight loss supplement containing 60 mg of the prescription drug orlistat, which helps dieters lose up to 50% more weight than diet and exercise alone.

Q:
How does Alli work?
A:

Taking Alli with meals helps your body absorb less of the fat in your food, resulting in lower calorie intake and, ultimately, weight loss. The body then excretes these fats.

Q:
Is Alli a miracle pill?
A:

No, Alli is not a “miracle pill.” It will not cause massive amounts of weight loss in a short amount of time.

Q:
How much does Alli cost?
A:

You can expect to pay more than $50 for 120 capsules, which is a 40-day supply. There are starter kits available, as well, that can cost between $30 and $60.

Q:
How should I take Alli?
A:

You take one Alli pill with each meal. The company suggests keeping fat intake below 15g each time. If you exceed this amount, you are at higher risk of side effects. You are also supposed to add one healthy snack in there.

Q:
Where can I buy Alli?
A:

Alli can be purchased using their Official Site.

Q:
Can I take more Alli to increase weight-loss?

A:

Yes, there have been reports of bowel leakage or spotting when Alli is used with a higher fat diet.

Q:

A:

Yes, you can eat healthy fats when taking Alli as long as you keep amounts of total fat below 15g per meal.

Q:
Do Alli diet pills work?
A:

Alli can help achieve weight loss by inhibiting the enzyme lipase. Lipase breaks down fat for absorption and storage in the digestive tract. By manipulating the breakdown process, Alli helps to decrease the amount of dietary fat absorbed in the intestines.

Does Alli have any side effects?
A:

Yes, Alli has a long list of potential side effects, including rashes, back pain, and bowel leakage. It is important to weigh the pros and cons and speak with a doctor before using Alli.

Q:
How do I take Alli?
A:

At most, three capsules of Alli can be taken per day. It’s also recommended to take a daily multivitamin at night. To see results, you need to eat 3 balanced meals with reduced calories and 1 snack per day. There should be approximately 15 grams of fat in each meal. The fat shouldn’t make up more than 30% of the meal’s calorie content.

Q:
What is the active ingredient in Alli?
A:

The active ingredient in a 60 mg capsule of Alli is Orlistat. The rest of the ingredients are inactive, contributing to the appearance, stability, and taste of the weight loss supplement. It’s available in the United States in doses of 120 mg with a medication prescription only. The prescription version was approved by the FDA in 1999 after intense clinical studies.

Q:
How much does Alli diet pill cost?
A:

The price of Alli diet capsules varies depending on the package size. On Amazon, you can acquire bottles containing 60 capsules for $56.34 and 120 capsules for $70.00. Meanwhile, at Walgreens, the cost is $79.99 for 120 capsules and $54.99 for 60 capsules. CVS Pharmacy offers a 60-capsule bottle for $43.99 and a 120-capsule bottle for $65.99.

If you prefer Walmart, their website lists the 60-capsule bottle at $43.94 and the 120-capsule bottle at $70.00. Additionally, Walmart provides various bundle options. On the Target website, a 60-capsule bottle is available for $44.99.

Q:
Is Orlistat and Alli the same thing?
A:

Orlistat is the name of the active ingredient. Alli is the over-the-counter capsule with a 60mg dose. The prescription version of Orlistat is called Xenical. It comes in a 120mg capsule. Both have the same recommended dosage of one capsule with a meal up to three times a day.

Q:
Does Alli help you lose belly fat?
A:

Alli is an over-the-counter weight loss aid. It is intended to help people lose weight when combined with a healthy diet and exercise regimen. It works by decreasing the absorption of fat from the diet, which can help reduce overall body fat levels and in some cases, specifically belly fat. However, it should be noted that Alli is only intended for adults who are overweight or obese, and as with any dietary supplement, it is always recommended to consult your physician before taking this product.

Q:
What are the benefits of using Alli?
A:

The benefits of using Alli include fat-blocking, easy to use, and enzyme-blocking.

Q:
Is Alli safe?
A:

Alli is FDA-approved for use by people over 18 years of age. However, it is best to have a BMI of at least 25 when taking Alli. Check with a doctor before using Alli if you are on any other medications, especially medications for weight loss.

Q:
Does Alli have competitors?
A:

Yes, Alli’s competitors include Lipozene, Relacore Extra, Trim-Fast, and TruControl.

Q:
Who manufactures Alli?
A:

Alli is manufactured by GlaxoSmithKline (GSK), a pharmaceutical company with a BBB rating of B-.

Q:
What is GSK’s return and exchange policy?
A:

GSK provides refunds for any GSK product purchased from one of the authorized sellers within 45 days of the date of purchase.

  • I have lost 13 lb
    leslie (Verified Purchase)

    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!

    • HEATHER

      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.

        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.

      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.

        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.

    I’ve been taking Alli for 2 weeks now & love it! Adjustments: Take my vitamins at nite, try to remember to take an Alli when I start my meal & “go” when my body says I gotta. 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!

    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.

        according to my doctor, alli will not affect thyroid meds. Alli is a digestive based med and doesn’t affect your metabolism.

      I am on MMI- My doctor recommended not taking alli until 4 hrs after you have taking your thyroid meds. As a result I only take 2 pills a day.

    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

    Reply
    • Marissa

      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.

      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.

      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.

      Keep in mind that everyone’s body will react differently. There may or may not be a significant change in your bowel movements. You can read more about Alli on the official website.

    I have been taking Alli for one week and have lost 4.5 lbs, coupled with a diet adjustment but have not exercised at all. Have had a few episodes of greasy stool after eating pizza or something with high grease but nothing bad, no uncontrolled bowel problems. No other negative effects either. So far I am loving it. It also motivates you to eat healthier.

      I agree with you. It motivates you to eat healthy or plan to go to restroom. I made the mistake of eating a bologna sandwich with 1 slice ch, is slice bologna and a few Doritos. NASTY!!! LOL Otherwise no side effects.

    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!

      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

      Reply
    • latonya

      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..

      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.

        Hair loss comes with shocking the body after a quick weight loss , lack of vitamins and lacking something in your diet, eating less carbs is a big factor in hair loss

      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.

      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.

      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.

      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.
