Weight loss includes loss of body fat and lean mass, which is the amount of protein (muscle) glycogen, water, minerals and electrolytes.
Typically, the first phase of the diet is characterized by a relatively large protein losses. The body uses primarily the proteins contained in the gastrointestinal tract and liver, and then – in skeletal muscle and, to a lesser extent, in the internal organs.
When a thin man lose 10 kg of fat he is risking to lose about 15 kg of muscle tissue, while in overweight person loss of a muscle mass decreases. It is important to understand that the intense loss of lean mass occur only in the first 4 weeks, that is, in the first phase of weight loss. As soon as the body lowers the base metabolic rate to a minimum, and proceeds to the second phase of the diet, the main source of energy becomes fat.
In general, the composition of the weight loss is determined by two factors – the initial constitution of the person and compliance with the diet.
The most common purpose when working on the body is the desire to reduce the percentage of body fat and to maintain or increase muscle mass. To do this, you need to understand what parameters will help you to achieve the desired result.
Weight loss and the rate of reduction of a fat mass depends on the balance between the diet and exercise.
Extremely low-calorie diet inhibits the metabolic rate and promotes greater disintegration of protein tissue than a balanced diet and gradual weight loss.
The less a person eats, the more the body tries to optimize processes and use the incoming energy efficient . In simple words, everything you eat will be stored as a fat!
