Fit for Life Diet

The Fit for Life Diet plan is a food combining diet, based upon a 1985 book of the same name by Harvey and Marilyn Diamond. The Diamonds maintain that certain types of foods shouldn’t be eaten together since if the body can’t digest them well, they sit in the body and become fat. This diet regime is designed as more of a lifestyle change and long-term dietary overhaul than as a short-term weight loss solution.
The Diamonds contend that you can lose weight without exercising or calorie counting by following some strict rules as to which foods you eat at certain times of the day and in specific combinations. On the Fit for Life diet, fruit is the only food you should eat from the time you awake until noon. You have your choice of foods for lunch and dinner, but starches and proteins are not to be mixed. That means you could have an all-carb meal including pasta, legumes, and vegetables or one heavy on protein. Water is not to be consumed with any meals and dairy products are rarely, if ever, eaten.
While this diet does incorporate raw fruits and vegetables which is a good thing from a nutritional perspective, it also has an array of less healthy characteristics. Scientific opinion is quite sceptical of food combining diets and there is no evidence that they actually work. This is listed as a fad diet by the American Dietetic Association, and some doctors warn that nutritional deficiencies are a possibility when following a food combining diet.
