of a small stomach pouch to restrict food intake and the
construction of bypasses of the duodenum and other segments of
the small intestine to cause malabsorption (decreased absorption

Very Low Calorie Diet (VLCD). A short-term weight loss diet,
VLCDs are commercially prepared formulas of 800 calories or less
