Protein contains amino acids, and muscles are made of them. Intense exercises may cause muscle rips and injury. Protein consumption helps repair and rebuild muscles
Protein synthesis creates new proteins. Increased protein consumption boosts muscular protein synthesis, which builds muscle and strength.
Positive balance means the body is absorbing more nitrogen from protein than it's excreting, which promotes muscular growth.
Food digestion, absorption, and processing need energy, known as the thermic effect of food (TEF). To digest and use protein, the body needs more calories than fats and carbs.
Satiating protein-rich meals lower appetite and calorie consumption. This may help you lose weight and provide enough energy for exercises.
Muscle development and recovery factors like insulin and growth hormone are affected by protein intake.
Strenuous exercise temporarily suppresses the immune system. Immune cells and antibodies, which fight infections, need protein.
