We recommend drinking Optislim Coconut and Lemon (48 hours detox) 4 times per day in between meals, for the best results consume fruits, vegetables, unsweetened jelly, and clear soups. It is best to avoid processed foods and grains, ensure that you are drinking a minimum of 1-2 litres of water whilst on the detox.

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.

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.

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.

Our Optislim For Her Shakes are not Halal certified.
Please be advised, our Optislim Plant-Based For Her shakes are halal suitable but not certified.

Yes – If you are a type 2, non-insulin dependent diabetic. However, it is important to maintain regular contact with your doctor during the program as your medication levels may need to be adjusted.

Please note: As an insulin dependent diabetic you would need to consult your doctor to check that this type of diet is appropriate for you.

The Optislim For Her shakes and Plant-Based shakes are mixed with water.
Please see above ‘How to use’ for directions.

The Optislim For Her Shakes contain Sucralose and Stevia.
Sucralose is a no-calorie, high quality sweetener that is made from sugar and tastes like sugar.

Each flavour in our ranges varies in taste as they all contain slightly different ingredients for added benefits.

If you have any medical conditions or are taking any medication we recommend that you seek advice from your healthcare professional so that we can assist you in using the best product for you. Rest assured, the products themselves are safe to use however various factors need to be considered when introducing a new diet.

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.

Yes, it is considered to have active ingredients.

Active ingredients are often referred to in either skincare or pharmaceutical products. Active ingredients are ingredients that create a physiological change in the body. For example, a Panadol capsule would contain the active ingredient inside the capsule however, the capsule itself would be ‘inactive’ as it is only the carrier for the medication.

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.
