This review is what happened after I obsessed for weeks over Optislim. We decided to dig deep, examining the ingredients, side effects, scientific research and level of customer care. Plus we sorted through all kinds of user comments and dieter reviews from the internet. Finally, we then summed up all the data and responses we found to give you the info you need.

What is Optislim?

First off, Optislim is an Australian weight-loss program that was originally developed to help morbidly obese patients with weight reduction. [1] This VLCD (very low calorie diet) incorporates total meal replacement and the meals are claimed to taste good and be affordable. [2] A LCD (low calorie diet) program is also available, and it involves partial meal replacement. The food products include cookies, bars, soups, shakes and main course dishes like beef stroganoff and chili con carne. These products can all be purchased via the main website. There are now four different types of programs; weight-loss, detoxing, toning and weight management.

From what we gathered, Optislim has been around since 1996. There are some success stories posted on the company website and a decent variety of low-calorie foods and supplements are available, but read on…

Optislim Taste – “A Concern?”

The first thing we looked into with OptiSlim was the taste. According to our Research Editor, “We found all sorts of negative customer reviews pertaining to the food and supplements. This is a major drawback because if you can’t stomach the diet foods/supplements involved, you probably can’t commit to the diet.” [3]

One customer said, “A waste of money and food is [bad].” [4]

“These shakes taste really awful. No Thanks!,” said another dieter.

Side Effects – “Another Drawback”

Some people have experienced OptiSlim side effects from the supplements. One customer commented, “My husband has been using Optislim and has been…dizzy.”

Another user stated, “When I stopped drinking it my headaches had gone. I went back on the shakes a month later and my headaches returned!!!”

The intensive research we’ve conducted has shown if there is a specific aspect of a diet program or supplement that is quite burdensome (too many side effects, unpleasant taste, a painful exercise) the odds of real fat loss success are not good. In other words, if Optislim does in fact lead to adverse reactions in a lot of people, this could be a real dilemma. [4]

The Science – “Any Evidence?”

We were unable to find any solid science provided on the official Optislim website. While we know that seriously reducing your daily caloric intake will lead to weight reduction, you can also accomplish this without the Optislim program. At DietSpotlight, we need to see published clinical research that supports the weight-loss product or program. [5]

The Bottom Line – Does Optislim Work?

So, should you invest in Optislim for weight-loss? [6] Well, we like Optislim’s longevity as a diet program and some positive comments we saw about it online. However, we have some reservations about it because it’s not backed by science. Moreover, we’re concerned about the unpleasant taste of the supplements and the side effects they can cause.

If you’d like to drop more weight, then we advise you to go with a diet program or weight-loss product that is backed by solid science, does not cause unpleasant side effects and is easy to use.

Among the best products we’ve seen in 2016 is one called Leptigen. Its unique formula is a blend of four ingredients, which have been proven in published scientific studies to kick-start metabolism and encourage more fat loss. We can’t find any complaints of harmful adverse effects and customer feedback around the web shows people are seeing solid results.

Furthermore, the makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a positive sign.

Previous OptiSlim Review (Updated January 1, 1970):

What is OptiSlim?

OptiSlim VLCD is a very low calorie diet system that replaces meals under the recommendations of a health professional. Within the diet industry, VLCD's are viewed as "extreme" weight loss options, and are usually carried out under a doctor's supervision. The shakes provided will allow a dieter to maintain his or her daily nutritional requirements and lose weight at the same time. OptiSlim Soups contain 25 vitamins and minerals. However, when under this diet arrangement, it is important to maintain fluid intake during the day. The recommended amount is about 2 liters per day.

Ingredients Used in OptiSlim

The ingredients will vary based upon the product used.

Product Features

OptiSlim is a very low calorie diet containing 3350kJ, which amounts to 800 calories or less per day. There are about four products from OptiSlim. These are VLCD Shakes, VLCD Soups, MAX Tablets and OptiSlim Shakers. OptiSlim Soups have seven sachets per pack that come in flavors of tomato, pumpkin and chicken. The OptiSlim Shakes come in milkshake taste and in three flavors Vanilla, chocolate and Espresso Coffee. They contain minerals, vitamins, and trace elements that come in balanced levels. OptiSlim tablets also come with the right and balanced amounts of vitamins and minerals. However, it is still advisable for someone under the OptiSlim program to ensure that he or she has a daily consumption of fibers, low starch vegetables like broccoli, mushrooms, lettuce, spinach, green beans or cucumbers.

People with diabetes, liver disease, gall bladder disease, kidney problems or cardiovascular diseases should first consult a doctor before starting on any VLCD regimen. This is because the program will usually affect the body's metabolism processes and may cause an individual to experience significant physical changes like weight loss. This may affect existing medical conditions. Thus, regular checkups and monitoring by a physician is required to manage these medical complications.

The Advantages of OptiSlim

  • OptiSlim has been shown to reduce the chances of one being overweight and obese.
  • Obesity has numerous complications that include high blood pressure, cardiovascular problems and other forms of cancer. Thus, one reduces the chances of getting these diseases.

The Disadvantages of OptiSlim

  • The use of OptiSlim causes a person to experience some unpleasant reactions including headaches, dizziness, constipation, bad breath, nausea and diarrhea.
  • Following the VLCD program will also cause a person to have an increased amount of uric acid in the body which may lead to the development of acute gout. Acute gout is very irritating and will usually require a doctor's assessment to reduce the discomfort.
  • A VLCD should only be followed under the strict care of a physician.

Conclusion

With only 800 calories or less in a day intake, OptiSlim VLCD programs are clearly one of the most effective weight loss programs on the market when followed under the care of a doctor. The backing of clinical trials on these products is evidence of their safety and effectiveness, but this safety is not something that should be determined by the individual. In order to lose weight effectively without a dangerously low amount of calories, we recommend a fat burner or other weight loss supplement and a healthy diet and exercise.

OptiSlim Side Effects:

OptiSlim claims to be a safe way to lose weight. While the majority of cases have been side effect-free, there are some users who report having issues. Although this doesn’t mean you’ll necessarily see side effects, it’s very important to take all risks into consideration before beginning use.

Dizziness

Dizziness is a feeling of light-headedness, weakness, and loss of balance. It’s as though you’re going to faint. If you start to become dizzy, be careful! You can fall over or pass out, which can lead to injury. Have a seat and ask someone around you for help.

What causes dizziness?

Dizziness is a common symptom of many conditions. You may be suffering from a sudden drop in blood pressure or blood volume. Hypoglycemia, or low blood sugar, is also known to provoke dizziness.

Headaches

Headaches range from mild pressure in your head to severe migraines. If the pain gets intense, it can interfere with your ability to function properly. You might even get light-headed.

What causes headaches?

Most headaches are caused by everyday stressors. They’re nothing to worry about. You simply haven’t been drinking enough water or getting enough sleep. Or you stayed out in the hot sun for too long. Headaches can also be a sign of a more serious illness. Concussion, ear infection, glaucoma, and high blood pressure can all make your head hurt. [1]

Nausea

When you’re nauseous, you have the urge to vomit. You may actually vomit, but sometimes the sensation dissipates without any incidents of vomiting. Often, nausea causes your stomach to have mild contractions as your stomach tries to eject everything inside. You may also experience sweating, dizziness, and stomach ache.

What causes nausea?

Nausea is often the result of food poisoning and motion sickness. You may also have a case of ulcer, gallbladder disease, or stomach virus.

Diarrhea

There’s nothing fun about having a liquid stool. You have to run to the bathroom every few minutes. Your stomach and rectum hurt. Usually, diarrhea goes hand-in-and with gassiness, stomach pain, and bloating.

What causes diarrhea?

Your stomach is probably infected with a virus, bacteria, or parasite. Or you may be suffering from irritable bowel syndrome. [2] Food intolerance and food allergy are also common causes of diarrhea.

Everyone’s body reacts differently to OptiSlim. To stay on the safe side, talk with your doctor about how its ingredients can affect your health. If you notice any side effects, stop using it immediately.

I’m on optifast one shake per day and losing half kilo per week. Great stuff very pleased. Will be starting on two shakes a day.

Hi, I’m 47 years old and have been told I need to lose 40kg. I gave up drinking and smoking 2 weeks ago and I’m proud of that but I’ve struggled with my weight my whole life. After getting a kick in the pants from my doctor, I really want to be healthy and happy. I’m giving Optislim a go. I think it’s great so far (4 days in) because in don’t have to weigh anything and obsess over food. I can have my shake and get on with something non food related. I have a big bowl of steamed vegies in the evening as well. I have lost 1.2kg in 4 days. Another benefit is that for years I’ve suffered with gastric reflux and heartburn and now, I’m glad to say it’s gone!

when do I take tabs before or after food or a replacement to food optislim Garcinia cambogia

Hi! For detailed product and usage instructions, please refer to the Optislim official website for more information.

Tell us your thoughhi I have just started optislim shakes I have one to shakes a day and very small meal at night is this correct way to lose wight with this product?? Thanks for any advice

The Optislim site says you can have up to 3 shakes a day when replacing your meals. Be sure to also at least 2 liters of water per day.

Hi

Also in a week what is ratio to loss the weight to using this tablet

is optislim approved by australian nutritionist or diet association

Most disgusting product and a company with no refunds on unused stock a waste of money and food DISGUSTING!

Hi i found out the shakes contain caffeine. Can you tell me how many mg of caffeine per serve? I might still be able to take them if its not too high..

Do optislim products contain any caffeine? I am very sensitive to caffeine and suffer severe withdrawal symptoms that require medical supervision if i ingest a lot of caffeine and then stop. I also suffer heart palpitations if I take fat burner tablets that utilise caffeine.

no they don’t

Just recievef my order and was told I was not able to take this products ad I have kidney failure and was told by drs and chemist that im unable to have the product could anyone please get back to me so I can send this back

My 16 year old daughter wants to try optislim, is it safe for her, she is not fat just wants to lost a little off her stomach

she just needs some tummy exercise not vlcd !

I’ve been on Optislim for almost four weeks, finding is easy, slowly losing 1kg per week. Headache the first two days but increased water intake, feeling great and never hungry like when on other diets. I have shake for breakfast and lunch, small meal for dinner. I can’t exercise. Still enjoying coffee & tea on low fat milk, no sugar or sweetener.

I had a headache too but I also cold turkey went off caffeine cos I can’t do coffee without sugar. Your headache might not be due to actual ingredients. Might be cos of something your not having any more.

I am just starting the Optislim VLCD, I am struggling to understand exactly the regimen to follow, can you give me a run down so that I know I am doing it correctly. Is it 3 meals a day being replaced with bars/shakes or are there snack times involved, I am very confused and dont find the website at all helpful

I’m having three product’s a day.
Shake for breakfast, sometimes blended with frozen berries.
Salad and chicken, fish or meat for one or two meals a day. But only non starchy veg. No pumpkin potatoes parsnip corn etc. Salad once a day and sometimes cooked veg once per day. A diet bar for after noon snack.
A diet dessert like optifast lemon or chocolate pudding.
Optislim and optifast are the same really so interchangeable.
Small serves of protein food and mininum 2 cups veg per day.
As much diet drink as I like.

Just started and it tastes great but im a diabetic and wondering what the GI of this product is as my sugars seem a little higher.

Are you feeling stressed by the dit?

i tried the opti slim shakes my blood levels were very high and i felt very unwell and my eyes went funny i am on insulin at night

I’m a type 2 diabetic and take Diabex. I’m due to have surgery later this year and need to lose weight, I’m using Optislim on the advice of my dietician and my blood levels have been really good, I feel great and have no side effects whatsoever.

Hi is it possible to use the shakes and tablets together?

Husband using Optislim been vomiting and dizzy

Iv just started talking it doctors orders as im struggling to lose my baby weight..iv been vomiting and really bad heart burn and feeling sick and no energy I hope it passes

Tell your doctor

Your headaches are caused by going into ketosis you just need to drink more water and should pass after a few days!

I’m about to have a gastric sleeve op in less than 2 weeks, most other patients are on Optifast but I am on Optislim, does Optislim reduce the size of the liver the same way Optifast does??

Whear i will buy in uae

Depends where you live
Local pharmacy perhaps
