The Fit For Life Diet states eating specific food combinations at specific times results in improved weight loss and energy.
They have developed their plan according to authored books such as:
"The Magic of Well-Being" by Judith Jackson, "Foods that Harm, Foods that Heal" by John M. Freeman M.D., and "Foods That Cause you to Lose Weight (The Negative Calorie Effect)" by Dr. Neil Barnard, M.D.
They use Biochemical Analyzation, Metabolic Typing and Genetic Predispositions to develop the programs.
They promote supplements, enzymes and vitamins, that are part of their Basic Body Maintenance group. These are at an additional cost.
Eat right for your metabolism, avoid foods not compatible to your body, avoid foods you may have sensitivities to and burn more than you eat.
The regular program costs $499.95 US or $599.95 Canadian. However, it appears they do offer specials quite often.
They require your blood type. If you don't know what your blood type is, they offer home testing kits for $9.95.
Each week you can choose a day that you will not have to follow the recommendations. They call it "Freebee Friday", but you can choose whatever day of the week you wish.
There is a lot of controversy about the "combination of foods" increasing weight loss. As of yet, there are no documented studies that confirm this is a fact.
