The diets high protein to reduce body fat and increase muscle mass are widely used by people who practice sports, bodybuilders and fitness training as it is a unique method of eliminating the excess fat.
The protein diets are based on reduced carbohydrate intake to a minimum of 40 to 60 grams per day and increased consumption of protein and fat. The proteins must be of high biological value, so the decrease in carbohydrates forces the body to use energy reserves of fat, without changing muscle mass.
The energy the body gets degraded using fatty acids and ketone bodies, which in turn stimulate the loss of appetite. Ketosis is maintained at a healthy because the same ketone bodies stimulate insulin secretion, which slows the ketosis. Thus, insulin is also controlled and baseline levels by promoting the consumption of lipids.
With increasing protein intake increases protein anabolism, protects muscle and increases energy expenditure as heat because the proteins have a higher specific dynamic action of carbohydrates and fats.
High protein diet allows the body to keep gaining muscle mass and low in fat, and although in diet lipid levels are slightly elevated cholesterol and lipoprotein levels remain stable or fall.
Replacement of carbohydrates is variable and depends on physical activity is performed, so an athlete who makes a daily activity can lead a high protein diet, but with minimal carbohydrates.
Note that this type of diet must be done under the supervision of a specialist and rule out any health problem or inconsistency with the food plan is okay. It is also important to note that high-protein diets alone do not increase muscle mass to achieve muscle growth is essential to have regular training and follow a balanced diet.
