The Science of OPTIFAST 800 Calorie Diet
OPTIFAST total meal replacement restricts your energy caloric intake of approximately 800 calories a day and still providing you with enough of all vitamins and minerals you need. During the first phase of the plan, OPTIFAST may include mild ketosis, a metabolic state where the body burns fat instead of carbohydrates as a primary energy source.
