Let's say a healthy person reduces the consumption of calories from fat protein and carbohydrates. Pretty soon, the glucose level falls, which reduces the production of insulin and includes fat mobilization, in other words the body suddenly, began to receive less energy than required to maintain all body processes.
In such a situation the body gives a clear signal: little energy - begins hunger. Body stops the synthesis of muscle tissue and slows down the process of burning the main source of energy - fat. In addition you can include the main defense mechanism - a strong sense of hunger.
The body struggles to make it clear that very little energy, and urgently need to refuel, fat cells in such a situation - the last thing that the body uses for energy, first in the course are the muscles and in fact they are responsible for basic metabolism, in other words when Restrictions on the body consumes its own muscle, less muscle - slower metabolism.
