Balanced, low-calorie diets and reduced ̶ portion size diets are the types that dietitians and other weight-management professionals most commonly prescribe. Although these diets are useful for short-term weight loss, none of them alone is associated with reliable, sustained weight loss.

These diets underlie most of the popular, commercial weight-loss programs, such as those advocated by Jenny Craig, Weight Watchers, Take Off Pounds Sensibly (TOPS), and Overeaters Anonymous (OA). The basic premise for people on these diets involves obtaining their detailed dietary inventory and using it to estimate their mean daily caloric intake.

A reasonable goal for the caloric deficit is based on the new goal for total daily calories. Meal plans are then devised to provide this total, divided among 3 or more meals throughout the day.
