Fit for Life (FFL) is a diet and lifestyle stemming from the principles of natural hygiene, an offshoot of naturopathic medicine. It is promoted mainly by the American writers Harvey and Marilyn Diamond.[1] As the title of the 1985 book suggests, Fit for Life claims that one can lose excess body weight and maintain good health via long term dietary and lifestyle practices, rather than short term dieting. In the Fit for Life book series many dietary principles are recommended including eating only fruit in the morning, eating predominantly "live...high-water-content" food, and if eating animal protein to avoid combining it with complex carbohydrates., ISBN13:B000NXY348 ISBN10:B000NXY348 Material Type:hardcover
