What is the potential impact of a high protein diet on body composition?

A high protein diet is associated with positive effects on body composition, particularly in supporting muscle retention and growth. Protein plays a critical role in muscle repair and synthesis, which is essential for individuals aiming to increase muscle mass or maintain muscle during weight loss. When combined with resistance training, a high protein intake can promote hypertrophy, which is the increase in the size of muscle fibers.

Additionally, protein has a higher thermic effect of food (TEF) compared to fats and carbohydrates, meaning it requires more energy to digest, absorb, and metabolize. This can contribute to a favorable calorie balance, aiding in body composition changes. Adequate protein intake is also crucial during weight loss phases to minimize muscle loss, making it beneficial for those looking to improve their body composition by losing fat while preserving or building muscle.

In contrast, other options either suggest a singular outcome not typically associated with high protein diets or overlook the nuanced effects of protein on body composition. Thus, focusing on the role of protein in muscle retention and growth highlights the advantageous impact of a high protein diet.
