The participants’ height and weight were measured. BMI was computed as the body weight (kg) divided by the square of the height (m). The dietary intake was assessed using a 3-day food diary (2 weekdays and 1 weekend) before starting the low calorie diet and supplements and also at the end of the study during last week. Dietary intake composition data were analyzed by “Nutritionist 4” (First Databank Inc., Hearst Corp., San Bruno, CA, USA).
