Like building a home, losing weight involves the interlocking of several pieces. The weight-loss architects at Physicians Weight Control build healthy physiques upon four pillars. Diet plans personalized to the client’s lifestyle control intake of nutrients and fat, fueling the clinic's aerobic-exercise plans. The last two pillars—appetite suppressants and vitamin supplements—combine to keep energy levels up and re-create the rush of swallowing a candy bar whole once the client starts eating smaller meals.
