very low calorie diet
A commercially available diet in which caloric intake may be from 400 to 800 kcal/day. This diet is usually in the form of a powdered supplement taken 3 to 5 times a day with large amounts of water. This diet can be effective, but the long-range efficacy in maintaining the weight loss may be discouraging. Vitamins and minerals are typically added to this diet because the small number of macronutrients consumed are inadequate for daily needs.
