very low calorie diet

(redirected from Very Low Calorie Diets)
A potentially dangerous fad diet that provides 300–700 kcal/day, which must be supplemented with high quality protein; given the risk of death through cardiac arrhythmias, starvation diets should be limited in duration
Adverse effects Orthostatic hypotension due to loss of sodium, decreased norepinephrine secretion, fatigue, hypothermia, cold intolerance, xeroderma, hair loss, dysmenorrhoea

very low-calorie diet

A diet that provides 300–700 kcal/day (normal intake is ±2500 kcal/day), which must be supplemented with high-quality protein. Given the risk of death due to intractable cardiac arrhythmias, the diet should be limited in duration.

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.
