what are true regarding the body's use of protein?
After strenuous exercise, muscles repair themselves by using available amino acids to synthesize new proteins. After engaging in intense physical activity, athletes may be able to enhance protein synthesis in their muscles by eating protein-rich foods. When athletes consume excess protein from foods and supplements and the body does not need the extra energy, the amino acids in the proteins will be used for building or repairing muscles. The carbohydrate-to-protein ratio in low-fat chocolate milk promotes energy and muscle recovery and protein balance after exercise.
Why does a low-carbohydrate, high-protein diet promote weight loss?
Carbohydrate intake promotes glycogen storage; for every gram of glycogen stored, your body stores 3 grams of water; when carbohydrate intake drops, so does the water weight usually associated with glycogen storage. Without adequate dietary carbohydrate, the liver is forced to make glucose from amino acids taken from the body's tissue proteins; protein tissue contains a lot of water and dismantling that protein results in water loss in the urine. The salt content of carbohydrate-containing foods tends to be higher than that of protein-containing foods; when high-carbohydrate foods are swapped for high-protein foods, salt intake is lower, resulting in less water retention. The amount of energy expended to digest and absorb high-protein foods is more than that required for high-carbohydrate foods; on a high-protein, low-carbohydrate diet, the metabolism speeds up and more water is lost through perspiration.
