Optifast - Diet Plan Outline

Optifast is a medically-supervised program of fortified liquid replacements, which eventually includes food bars and more regular food. Counseling, lifestyle change and exercise are central to the program. A dieter is assigned to an 800, 950, or 1200 calorie plan. It is directed by a staff of physicians, nurses and dietitians. Costs vary between $1500-$3000.

Pro/Con: maybe the most expensive. Perhaps only for the seriously obese. Ask your doctor.
