Studies show that blocking mTOR with the drug rapamycin can prevent the contraction-induced increase in skeletal muscle protein synthesis in humans. This strongly suggests that the mechanistic Target of Rapamycin, or mTOR, is a crucial component needed for muscle growth, but is it the entire story?

A 2017 study found that consuming whole eggs after resistance exercise results in greater stimulation of muscle protein synthesis compared to egg whites, despite the same protein content. This suggests that whole eggs, not just their protein, may uniquely stimulate mTOR activation, particularly in conjunction with physical activity.

Research has shown that consuming whey protein after resistance exercise significantly enhances the activation of anabolic signaling pathways. This potent effect is driven by the fact that whey protein activates mTOR, the master regulator of muscle protein synthesis, triggering a cascade of events that leads to muscle repair and growth.
