ROTATION DIET: HOW TO INCREASE YOUR METABOLIC NEEDS WITH DIET

Although a calorie is a calorie in the laboratory, all calories are not the same to the human body.

For a long time even the best, most informed nutritionists claimed that it didn't matter where your calories came from. They said that all calories meant the same thing in terms of energy to the human body. Recent research disproves this statement.

Fat, for example, is easily converted to a form that your body can use for energy, and it's very easy to convert dietary fat to body fat for storage. It is especially easy to gain weight if you happen to eat more fat than your daily energy requirements.

Carbohydrates and protein need a great deal more digestive work to convert their energy than does fat, and this results in a "wasting" of some of the energy. That is, while the calorie count for a carbohydrate or protein food may be accurate in your calorie book, your body doesn't end up using all the listed calories for energy in vital processes. Some of the calories are burned up and thrown off as heat.

Similarly, if you should overeat on either carbohydrates or protein, the body has to work much harder to change these nutrients into fat than it does to change dietary fat into body fat.

In fact, it takes between four and five times more energy to convert carbohydrate and protein to fat than to convert dietary fat to body fat.

Perhaps this will become intuitively evident if you just imagine a quantity equal to two teaspoons of fat or oil sitting in a dish next to a fairly large apple. Both food items will be about equal in calories as measured in the laboratory apparatus that determines how many calories they each contain (about 70 to 80 calories). But your body will have to work a lot harder to change the calories in that apple into body fat than it has to work to change the calories in that fat or oil into body fat.

It takes about 5 percent of the energy content of dietary fat to convert it to body fat. It takes 20 to 25 percent of the energy in carbohydrate and protein to turn these nutrients into body fat.

Obviously, if you substitute carbohydrate or protein calories for fat calories, you can end up eating many calories more and still not gain any weight. Even though your total calorie count is up, you have increased your metabolic needs by making the body work harder in the process of digestion. So, you don't gain any weight.
