Why is a high intake of protein for athletes discouraged?

Question

What will be an ideal response?

Answer 1

Consuming more protein than the body needs or can use will not lead to greater muscle mass. Eating high carbohydrate, moderate protein foods immediately after a weight training workout can enhance the anabolic effect of the activity. This most likely increases blood concentrations of insulin and growth hormone and contributes to protein synthesis. Remember, it is impossible to increase muscle mass simply by eating protein; putting physical strain on muscle through strength training or other physical activity is needed, as is adequate protein intake to support growth and recovery.

Protein intakes above recommendations result in an increased use of amino acids for energy needs and has disadvantages, such as insufficient carbohydrate intake and increased urine production, which may interfere with body hydration. No advantages, such as an increase in muscle protein synthesis, are seen. Despite marketing claims, protein supplements are an expensive and unnecessary part of a fitness plan.
