Counting calories
Calories are merely a measure of the energy content of the food we eat. They can be valuable for calculating the energy content of a meal or the nutrients in it - carbohydrates, fat and protein. But when it comes to regulating our weight, what we need to care about is the effect those nutrients have on the hormonal regulation of the fat tissue. This is simply a different issue. We are concerned in particular with the effect of the carbohydrates we consume on insulin secretion. And so the calories of carbohydrates consumed and the form in which those carbohydrates come are meaningful. Restrict carbohydrates and fat is mobilized from the fat tissue and burned for fuel: appetite is reduced, as a result, and more energy is expended.
