It’s important to remember that weight loss varies from person to person depending on many factors such as start weight, age, metabolism, if you’re doing exercise, how many meals you’re replacing and if you have any medical conditions.

Generally, when you are on the Optislim meal replacement program, you can expect lose about 1 kg a week, more or less depending on the above factors.

Our Optislim VLCD range is flexible, there are three phases to choose from to suit your weight loss goals.

  • Rapid Weight Loss (Replace 3 meals a day)
  • Steady Weight Loss (Replace 2 meals a day)
  • Easy Maintenance (Replace 1 meal a day)

We at Optislim believe that the healthiest way to lose weight is to reduce calorie intake whilst still providing all the vitamins, minerals, proteins and carbohydrates the body needs to function normally. We have a list of recommend food to incorporate whilst on our weight loss program to ensure that you achieve the best results. To view the recommended meal plan please visit www.cluboptislim.com.au

Yes of course, the steady weight loss phase includes 1-2 healthy snacks, this also applies if you decide to replace one meal a day. We advise consuming snacks between your meals so that you don’t feel hungry but ensuring that total calories do not exceed the average daily allowance. Snacks are an important part of the program and should be under 100 calories. They not only help regulate metabolism but they assist with feeling hungry therefore, reducing the chances of binge eating.

It is okay to have coffee or tea while you are on the program, however, it is important to remember that if you are incorporating it into your diet you are also adding calories so it is best to have it in moderation. Try having no more than 2 a day.

There are also few ways that you can reduce the amount of calories in coffee:

  • Reducing the amount of sugar and milk that you have
  • Using skim milk instead of full cream
  • Using a sweetener such as ‘Equal’ or ‘Sugarine’ instead of sugar

No, by following your daily calorie allowance, this provides you’re body with less energy than it needs for its basic function therefore, you will still lose weight even if you don’t exercise. But of course the more exercise you do the more weight you will lose, so you are in full control of the pace of your weight loss.

Our Optislim VLCD range is quite flexible where you can replace a 1, 2 or 3 meals per day. If you are replacing 1-2 meals per day, you can continue on this phase for as long as you need to. However, if you are replacing 3 meals, keep in mind that this phase is designed to produce rapid weight loss for people with a BMI greater than 30. We recommend that this phase is followed no longer than 3 weeks without medical supervision and a maximum of 12 weeks under medical supervision.

It is very important to consume at least 2 litres of water daily, in addition to the water/skim milk used to prepare the shakes. Adequate fluid intake is extremely important to ensure that the body remains hydrated and that the waste products from the fat burning process are eliminated from the body. To make water more interesting try infusing it with fruit such as lemon, lime, orange or fresh berries.

It is advised not to be consumed by children or adolescents as children need a wide range of nutrients for healthy growth and development however, this advice does not take into account your individual circumstances. Optislim can be consumed by children but only with approval and under supervision from a Healthcare Professional, if it is seen that weight loss is of more benefit to their current health situation.

We recommend people over the age of 65 seek medical advice before beginning the Optislim program. Rest assured, the products themselves are safe to use however various factors need to be considered for this age bracket relating to current medical status and whether you are taking any medications as some medications require restrictions with certain vitamins and minerals which the Optislim products do contain.

Our Optislim VLCD and Optislim VLCD Platinum are formulated as a complete meal replacement meaning that you will receive all your daily nutritional requirements when you use three per day.

Optislim VLCD is mixed with water and the Platinum is mixed with skim milk. The Platinum range also contains additional ingredients to further assist with your weight loss. These include Glucomannan to help keep you fuller, Ginseng to help with your energy levels and Green Coffee Extract to help with fat burning.

It is important to use skim milk whilst on the Platinum shakes as they are not nutritionally complete without this added ingredient. However, the Platinum shakes can be made up with water, almond or coconut milk as a snack. Please note: when mixing with anything other than milk, it will change the nutrient values depicted on the nutritional panel such as calories and fats, making it difficult to track how much of each nutrient you are having daily.


Because of the fibres in the shake, it is normal for it to become more viscous over time therefore, it is important to drink it immediately after preparation.

OptiBiome promotes a longer feeling of fullness by gently expanding in the stomach and gelling activity delays gastric emptying.

OptiBiome stimulates the growth of positive bacteria in the digestive tract and may even assist with IBS according to a case study.

Consumer studies show an average weight loss of up to 1.3kgs per week and reduced calorie intake and lower levels of cravings.

It is quite normal to experience increased wind/flatulence as the body adjusts to the extra fibre from the shake and will naturally improve after a few days. We suggest drinking lots of water to assist the breakdown of these fibres. Headaches can also be a normal side effect as your body adjusts to your new diet and lower sugar intakes, this typically lasts a couple of days. If symptoms persist, please seek advice from your Healthcare Professional.
