How does a high protein diet influence weight management?

A high protein diet influences weight management primarily by increasing metabolic rate. When a person consumes a diet rich in protein, the body expends more energy to digest, absorb, and metabolize the protein compared to fats and carbohydrates. This phenomenon is known as the thermic effect of food (TEF). Proteins have a higher thermic effect, which means that the body burns more calories during the digestion of protein-rich foods.

Additionally, a high protein intake can help preserve muscle mass while losing weight, which is crucial for maintaining a higher basal metabolic rate. Muscle tissue burns more calories at rest compared to fat tissue, aiding in overall weight management efforts. A higher metabolic rate through a protein-rich diet can promote fat loss while minimizing muscle loss, making it a beneficial approach for those looking to manage their weight effectively.

The other answer choices do not accurately reflect the effects of a high protein diet on weight management.
