Questions about Very Low Calorie Diet (VLCD)

Very Low Calorie Diet (VLCD) – are formulated, nutritionally complete, liquid or solid meal containing 3,350kJ (800 calories) or less per day, when used 3 serves a day. VLCD formulas contain appropriate levels of macro and micronutrients to ensure that all daily nutritional requirements are met.

VLCDs provide an amount of energy that is significantly less than the amount the body needs each day. This forces the body to start using its own fat stores as the main source of energy resulting in weight loss.

VLCD should be used by people requiring weight loss when it is essential to health and well-being as recommended and supervised by a Healthcare Professional.

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.

People who have acute cerebrovascular or cardiovascular disease (including unstable angina) kidney disease, liver disease, type 1 diabetes or severe psychological disturbances should not follow a VLCD.

As per CODEX Standard for Formula foods for use in Very Low Energy Diets for weight reduction, consumption should be not less than 50g protein.

For Steady Weight Loss and Easy Maintenance, healthy snacks should be introduced daily, ensuring total calories consumed do not exceed your calorie allowance. When you first start on a VLCD you may find that you feel quite hungry during the day. This feeling usually subsides after a few days once the body adjusts to a lower calorie intake. To reduce hunger and to contribute to your daily fibre intake, it is advisable that you consume at least 2 cups of low starch vegetables each day. Vegetables should be eaten either raw, steamed or stir-fried in no more than 1 tsp of oil. Flavourings such as ginger, garlic, parsley, basil, mint, lemon juice, lime juice, chilli, chives and low salt soy sauce can be used to add flavour. Additional oils and butter are not recommended. Avoid high starch vegetables such as pumpkin, potato, green peas, corn, sweet potato and parsnip as these are higher in calories and may slow your weight loss. Snacks should be healthy and well balanced, we recommend that each snack should be under 100 calories and consumed in between meals. For more information on recommended vegetables, snacks and fruits, refer to the leaflet inside BioSlim VLCD shakes.

2 litres of water, in addition to water used to prepare the shakes should be consumed daily. 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 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 an artificial sweetener such as ‘Equal’ or ‘Sugarine’ instead of sugar

The shakes are very versatile and you can adjust the shakes to suit your taste such as adding in a fresh banana, low fat yoghurt and blending it up like a smoothie or sprinkling the powder on top of cereal, just ensure that you account for any additional calories if you choose to do this.

Mild exercise should be incorporated into your weight loss program to assist with preserving lean muscle mass and to further assist with your weight loss. Start slowly and as you start to lose weight and become more confident you can increase your exercise. Aim for a goal of 20-30 minutes per day, 3-4 times per week. It is essential to check with your Healthcare Professional before commencing any exercise plan.

Rapid weight loss on a VLCD program can lead to a significant increase in uric acid in some individuals, which can result in the development of acute gout. Other possible side effects include fatigue, bad breath, constipation, nausea and diarrhoea may be experienced. It is important to further increase your fluid intake if you begin taking a fibre supplement. Increasing your fluid intake can also help with headaches which can be experienced when starting a VLCD diet, see ‘Fluid Intake’ section of the BioSlim leaflet inside each BioSlim VLCD shakes.

Bad breath can be refreshed by chewing on a low-calorie mint or a sugar free chewing gum. The most common, serious side effect seen with a VLCD is the formation of gallstones. Although obesity increases the risk of developing gallstones, it is also common for them to develop during periods of rapid weight loss. Please report any abdominal discomfort to your Doctor for assessment.
