Calorie Restriction

Models restrict their calorie intake each day to lose weight or maintain a low weight. A low-calorie intake for the average adult female is 1,200 calories per day. For the average male, 1,600 calories per day is considered a low-calorie intake.

Exercise

Models maintain rigorous exercise programs. Those who exercise on a consistent basis (at least three to four times per week for 60 minutes each session) tend to have faster resting metabolic rates than those who do not. A high metabolic rate causes energy (calories) to be expended by the body at a faster rate.

Water Intake

Models tend to avoid high-calorie liquids and drink plenty of water. Water helps rid the body of toxins and flushes excess salt. A diet high in sodium and low in water results in excess water weight being stored.

Cleansing Diets

Models often use cleansing diets to lose weight. Many contain colon-cleansing herbs and psyllium husks, along with a low-calorie intake including plenty of fresh fruits and vegetables. Cleansing diets last about three days.

Considerations

Before employing any method to lose weight quickly, consult your physician to make sure you are healthy enough to do so.
