Fit for Life

Cover of Fit For Life (1985 edition)

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 book series describes a fad diet which specifies 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 list it as a fad diet.Cite error: A <ref> tag is missing the closing </ref> (see the help page). [1] which sold millions of copies,[2][3] over 12 million according to Harvey Diamond.[4] Harvey Diamond has also appeared on dozens of television talk shows promoting his theories.[2] In 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 principles and veganism to increase energy levels in his book Unlimited Power.

Controversy[edit]

Scientific reception[edit]

Health experts and science writers have dismissed the book as quackery.[5][6][7]

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.[2]

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.[2][8]
