"It is not that important what and how much you eat, but rather when and in what combinations”, – claim the authors of the diet that became a real bomb in the world of nutrition in the early 80-s. Harvey and Marilyn Diamond, the creators of the Fit for Life program, used the idea of food combining in their diet plan.
This idea originated at the turn of the century was not altogether new but the authors managed to create their own point of view on the food combining issue and its benefits for human health. Harvey and Marilyn Diamond wrote the fastest bestselling book in the US diet history that was sold in 12 million copies in more than 80 countries all over the world.
After its appearance on the market in 1985 Fit for Life diet had many followers as well as opponents. The opponents criticized the lack of scientific background behind the whole program and the followers were attracted by its novelty and simplicity.
The central premise of the Diamonds’ diet is the point when and how one eats. The authors assure that certain foods when eaten improperly mixed are very hard to digest. People gain weight not due to overeating but due to the "wrong" combination of consumed foods, for example, protein food can’t be eaten together with starchy foods or fruit can't be consumed at the end of the meal.
According to the authors incorrectly combined foods become “rotten”. Because of poor digestion many toxic by-products are formed and are badly eliminated from human's body. These toxic residues are stored in fat tissues; that’s why people become overweight and obese. To prevent this process it is necessary to eat only one “concentrated” food per meal and the most of the diet food should consist of high water foods, preferably fruit and vegetables.
As the title of the diet suggests Fit for Life is not a short term diet with quick results. It is rather long term dietary and lifestyle strategy. There are no specific indications as to how many pounds will be lost during a certain period of time but many benefits are promised, such as increased energy level, general improvement of the health condition and purification of the organism.
Nobody would deny the usefulness of fresh fruit and vegetables as their consumption decreases the risk of developing of heart disease and cancer. The diet doesn't imply calorie counting and extra expenses for product choices. One can eat as much of the specific food as desired without portion control.
The critics state that fruit-vegetable diet isn’t able to provide the body with all necessary nutrients. Restriction of animal protein and dairy products can create deficiencies in calcium, zinc, vitamin D and iron. Besides food combing rules are often complicated and are not easy to follow which can lead to the total elimination of some food groups.
