Optislim is a company focused on promoting weight loss through food. The claim of rapid weight loss relies on you following a low-calorie diet or a very low-calorie diet. Research (i.e. Healthcare) shows some very low-calorie diets are unsafe.
A licensed medical professional monitors most calorie-restrictive diets, claims Livestrong; this plan isn’t monitored. However, our team wanted to understand better the potential benefits of dietary changes as it relates to weight loss. So, we focused on the meal plans, benefits of calorie restrictions and research supporting the claims. Then, we gathered the facts to give you the bottom line.
OptiSlim can be purchased through their Official Site.
What is Optislim?
First off, Optislim is an Australian weight-loss program that was originally developed to help obese patients with weight reduction. This VLCD (very low calorie diet) incorporates total meal replacement and the meals are claimed to taste good and be affordable. 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…
Taste of Optislim – “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.”
One customer said, “A waste of money and food is [bad].”
“These shakes taste really awful. No Thanks!,” said another dieter.

Side Effects – “A 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.
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. In fact, according to the Centers for Disease Control, reducing caloric intake and fasting can be done by simply keeping track of your food and following an eating time schedule.
At DietSpotlight, we need to see published clinical research that supports the weight-loss product or program.
“I’ve lost 2.5kg so far – It takes a while (a week or so) to get used to the taste of Optislim shakes. Bought them from Chemist Warehouse as they are the cheapest, 21 sachets for $25. Tried the Vanilla (my favourite), Chocolate and Strawberry. My advice is to start off using one shake to replace one meal for a week or so. Eat real food for the other two meals of the day, so your body gets use to drinking a liquid diet eventually. I started off with one shake per day and real food, exercising alot e.g. lap swimming and have lost 2.5 kg over 3 weeks. Be patient and don’t expect to lose more than 1kg a week, anything more than that is dangerous. Also if you have any issues consult your own doctor. I’m determined to make this work and lose another 15kg in 3 months. Good luck!!”
“Chocolate shake had unremarkable taste and consistency. I experienced upset stomach, headache & anxiety each time after only having one shake on two separate occasions. EXTREMELY POOR CUSTOMER SERVICE from Optislim.”
“Great product – I have tried strawberry and vanilla, and I really like the taste, (I do add ice to my shake) I don’t eat chocolate flavoured anything so haven’t tasted that. I can lose weight very easily on this product, but after the 4th day of any diet I get hungry. More will power needed. I wish they had a shake for that!”
The Bottom Line – Does Optislim Work?
So, should you invest in Optislim for weight-loss? 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 and is easy to use.
Among the best products we’ve seen this year is a program called Noom. Its with human coaching and personalized meal plans that Noom sets the standard for weight-loss support. This is more than an app it’s a support system customized for you.
