Very low calorie diet (VLCD) is a diet with very or extremely low daily food energy consumption. It is defined as a diet of 800 kilocalories (3,300 kJ) per day or less. VLCDs are formulated, nutritionally complete, liquid meals containing 800 kilocalories or less per day. VLCDs also contain the recommended daily requirements for vitamins, minerals, trace elements, fatty acids and protein. Carbohydrate may be entirely absent, or substituted for a portion of the protein; this choice has important metabolic effects. The VLCD products are usually a powder which is mixed with water or another low-food-energy liquid. The VLCD is prescribed on a case to case basis for rapid weight loss (about 1.5 to 2.5 kilograms or 3 to 5 pounds per week) in patients with Body Mass Index of 30 and above. The health care provider can recommend the diet to a patient with a BMI between 27 and 30 if the medical complications the patient has due to being overweight present serious health risks.
Famous quotes containing the word diet:
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
