OptiSlim Review - 5 Things You Need to Know
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 the most extremely calorie-restrictive diets; this plan isn’t monitored. However, our team wanted to understand better the potential benefits of dietary changes related to weight loss. So, we focused on the meal plans, the 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?
Optislim is an Australian weight-loss program initially developed to help obese patients with weight reduction. This VLCD (very low-calorie diet) incorporates total meal replacement, and the meals supposedly taste good and are affordable. An 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 are available on the main website. There are now four different types of programs; weight loss, detoxing, toning, and weight management.
Can you lose weight with meal replacements? Let’s take a brief look at what research has to say.
- Obesity Reviews – Though “Meal replacements are generally not recommended in clinical guidelines for the management of obesity,” research shows they are effective.
- The American Journal of Clinical Nutrition – There’s even some evidence the meal replacement works best for lasting weight loss when combined with behavior therapy.
- Gastroenterology – The trouble is, keeping weight off is hard. “Maintaining weight losses in the long term remains the biggest challenge and is undermined by an “obesogenic” environment and biological adaptations that accompany weight loss.”
From what we gathered, Optislim has been around since 1996. Some success stories posted on the company website and a decent variety of low-calorie foods and supplements are available but read on.

Optislim and the Better Business Bureau (BBB)
Optislim is not mentioned by the BBB. No filed has been opened, so no customer or BBB rating. The likely reason is that Optislim is located in Australia where it may appear on the local version of the BBB there.
Taste of Optislim – “A Concern?”
The first thing we looked into with OptiSlim was the taste. Our Research Editor states, “We found all sorts of negative customer reviews about 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 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 could not find any solid science provided on the official Optislim website. While we know 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 keeping track of your food and following an eating schedule.
When it comes to very-low-calorie diets, the research is mixed. While research published in Obesity (Silver Spring) found this kind of dieting did not cause more weight loss than regular low-calorie diets, a study in the Scandinavian Journal of Primary Health Care found individuals doing this kind of dieting found weight loss success even after a year.
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 backed by solid science and easy to use.
Among the best products we’ve seen this year is a program called Noom. It’s 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 customized support system.
Furthermore, we’re so confident that you’ll love Noom that Dietspotlight readers gain access to a free trial offer for a limited time.Learn More About Noom »

just want to know if optislim shakes can be taken with cold skim milk instead of water because my friend is using another brand shake with skim milk and she fells really full than i do with water
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!

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 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.
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.

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

Tell your doctor
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??
I used optislim before gastric sleeve op and it worked. I followed doctors instructions and lost weight quickly to help with op. I have no experience with optfast.

Does theOptiSlim shake contain any fibre? and if not, why not?
Yes, you’ll find that it will contain inulin, a fibre that promotes bowl movements. Some people will experience runny stools as a result but I think they’d be in the minority, shakes tend to bind you up so the inulin counteracts that a bit.
Too many negatives. Why put inulin in the first place. That then needs to be countered by binders? That in itse
Why put inulin that then needs to be bound up. Too many negatives with the product. I was going to try it until I read the reviews. Better to stick to fresh food that you prepare yourself
What ever ❣️
