Fit for Life (FFL) is a diet and lifestyle book series stemming from the principles of Natural Hygiene. It is promoted mainly by the American writers Harvey and Marilyn Diamond. The 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, and the American Dietetic Association and the American Academy of Family Physicians list it as a fad diet.
