Fit for Life
(FFL) is a diet and lifestyle book series stemming from the principles of orthopathy. It is promoted mainly by the American writers Harvey and Marilyn Diamond.[1] The Fit for Life
Fit for Life
book series recommends dietary principles including eating only fruit in the morning, eating predominantly "live" and "high-water-content" food, and if eating animal protein to avoid combining it with complex carbohydrates. While the diet has been praised for encouraging the consumption of raw fruits and vegetables, several other aspects of the diet have been disputed by dietitians and nutritionists,[1] and the American Dietetic Association and the American Academy of Family Physicians

Description[edit] The diet is based on Diamond's exploration of Herbert M. Shelton theories of food combining. Both authors claimed to be able to bring about weight loss without the need to count calories or undertake anything more than a reasonable exercise program. In the first version of the program, Diamond claimed that if one eats the foods in the wrong combination they "cause fermentation" in the stomach. This in turns gives rise to the destruction of valuable enzymes & nutrients. Diamond categorized foods into two groups : "dead foods" that "clog" the body, and "living foods" that "cleanse" it. According to Fit for Life
Fit for Life
principles, dead foods are those that have highly refined or highly processed origins; while living foods are raw fruits and vegetables. The basic points of Fit for Life
Fit for Life
are as follows:[1]

are best eaten fresh and raw. Where possible they should be eaten alone. Carbohydrates
& Proteins
should never be combined in the one meal. Water dilutes stomach digestive juices and should never be drunk at meals. Dairy products are considered of limited value and because of their allergic capacity, should seldom, if ever, be eaten.

In the 2000s, the Fit for Life
Fit for Life
system added the Personalized FFL Weight Management Program, which employs proprietary protocols called Biochemical "Analyzation", Metabolic Typing and Genetic Predispositions. The Diamonds claim that these protocols allow the personalization of the diet, which thus customized is effective only for one individual, and can be used for that person's entire life. This version of the diet also puts less emphasis on "live" and "dead" foods, and instead talks of "enzyme deficient foods". The Diamonds posit that enzymes that digest proteins interfere with enzymes that digest carbohydrates, justifying some of the rules above. They also began to sell nutritional supplements, advertised as enzyme supplements, many of which are strongly recommended in the newest version of FFL.[1] Publications and marketing[edit] The diet came to public attention in the mid-1980s with the publication of Fit for Life, a New York Times
New York Times
best seller[4][5] which sold millions of copies,[1][6] over 12 million according to Harvey Diamond.[7] Harvey Diamond has also appeared on dozens of television talk shows promoting his theories.[1] In Fit for Life
Fit for Life
II (1989) the Diamonds warned against eating artificial food additives such as hydrogenated vegetable oil, which at the time was being promoted by the food industry as a healthy alternative to saturated fat. Tony Robbins promoted the Fit for Life
Fit for Life
principles and veganism to increase energy levels in his book Unlimited Power. Book series[edit]

Controversy[edit] Scientific reception[edit] Health experts and science writers have dismissed the book as quackery.[8][9][10] The rigor of study underlying Harvey Diamond's credentials have been disputed, which has drawn questions about his competence to write about nutrition, because his doctoral degree came from the American College of Life Science, a non-accredited correspondence school founded in 1982 by T.C. Fry, who did not graduate high school or undergo a formal accreditation process himself. FFL's personalized diet program has been criticized for providing a "Clinical Manual" that is heavily infused with alternative medicine claims about how the body works, some of which may be scientifically inaccurate or not accepted by conventional medicine.[1] Despite the fact that FFL web site mentioned "clinical trials", many of the proposed principles and benefits of FFL diet are not supported by citations to any scholarly research, and some of the claims have actually been directly refuted by scientific research. For example, a dissociated diet as that advertised by FFL is no more effective for weight loss than a calorie-restricted diet.[1][11] See also[edit]
