Lean body mass preservation via increased protein intake

"Lean body mass preservation via increased protein intake" is not a single molecule or receptor, but rather describes a physiological outcome—namely the maintenance or increase of skeletal muscle and other non-fat tissues through dietary strategies that emphasize higher or optimized levels of dietary protein. The underlying biological processes involve the stimulation of muscle protein synthesis and reduction in muscle protein breakdown, which are regulated by complex metabolic pathways responsive to both nutritional and exercise stimuli[1][2][3]. Key amino acids such as leucine play an important role in triggering anabolic signaling for new muscle proteins, particularly after resistance exercise or during recovery from catabolic states[1][2]. While clinical studies have examined whether increasing daily dietary protein above recommended levels preserves lean body mass—especially in older adults—the results are mixed; some trials show no significant benefit beyond standard recommendations unless combined with other interventions like resistance training or anabolic hormones[4]. This entry does not correspond to any canonical drug target such as an enzyme, receptor, transporter, or transcription factor. Summary: This is not a valid therapeutic target at the molecular level. It refers instead to a nutritional intervention strategy affecting whole-body physiology through multiple downstream targets involved in skeletal muscle metabolism.
