The VKM Panel on nutrition, dietetic products novel food and allergy has concluded that, on a daily basis, VLCD products should provide a minimum of 55 g carbohydrates, 10 g fibres, 50 g high quality protein and 7 g fat, including 3 g from linoleic acid and 0.5 g from α-linolenic acid.

Very low calorie diets (VLCD products) are formulated products with 450 – 800 kcal per day intended to replace the whole diet. Regulation of VLCD is not harmonised in the EU, andthere is no specific national Norwegian legislation for these products.

The Norwegian Food Safety Authority has requested VKM to propose minimum and maximum limits for the content of fat/ fatty acids, protein, carbohydrates, vitamins and minerals in VLCD productsbased on acknowledged scientific documentation.

VKM is also asked to evaluate if VLCD products are suitable in the treatment of obese subjects with type 2 diabetes, and possible contraindications for use of VLCD.

Based on the available scientific literature, the VKM Panel on nutrition, dietetic products novel food and allergy has concluded that, on a daily basis, VLCD products should provide minimum 55 g carbohydrates, 10 g fibres, 50 g high quality protein and 7 g fat, including 3 g from linoleic acid and 0.5 g from α-linolenic acid. The amino acid scoring pattern should be in accordance with the protein-digestibility-corrected amino acid score.

VLCD products should provide minimum 10 μg vitamin D per day, and the minimum recommended daily intake for the other vitamins and minerals.

No maximum limits are suggested for carbohydrates, protein or fat, as the energy will be the limiting factor. The fibre content should not exceed 30 g per day, and the VKM Panel recommends that the maximum limits for vitamins, minerals and trace elements should equal two times the recommended daily intake.

VLCD will give short-term weight loss and improvement in blood pressure, serum lipids and glycemia in obese subjects with type 2 diabetes, and no serious adverse effects have been reported.

VLCD may impede the educational process needed in the treatment of diabetes, and should therefore only be used as part of an educational program in obese subjects with type 2 diabetes, and only under medical supervision.
