For individuals with larger body types, which macronutrient is most critical to optimize for its combined effects on maximizing muscle protein synthesis, enhancing satiety, and leveraging a high thermic effect during a caloric deficit?

For individuals with larger body types in a caloric deficit, the macronutrient most critical to optimize for its combined effects on maximizing muscle protein synthesis, enhancing satiety, and leveraging a high thermic effect is protein. Protein is composed of amino acids, which are the fundamental building blocks for tissues in the body, including muscle. Optimizing protein intake maximizes muscle protein synthesis (MPS), which is the process of building new muscle proteins. When the body is in a caloric deficit, there is an increased risk of muscle loss. Adequate protein provides the necessary amino acids, such as leucine, which directly signals the body to initiate muscle repair and growth, thereby helping to preserve existing muscle mass a....
