Protein Timing & Muscle
topic
Muscle protein synthesis is maximized by distributing protein intake in 3–5 servings of 20–40g across the day (each serving providing the approximately 3g of leucine required to maximally stimulate the mTOR pathway), consuming protein within 1–2 hours post-exercise (the anabolic window when protein synthetic machinery is most sensitive), and including protein in the final meal before sleep (casein protein producing sustained amino acid availability during overnight muscle repair driven by growth hormone).
Role
Protein timing optimization produces significantly greater muscle protein synthesis outcomes from the same total daily protein intake — yet the majority of people attempting to build or maintain muscle mass are consuming most of their protein in one or two large servings, often at dinner, while eating protein-sparse breakfasts and lunches, missing the mTOR stimulation opportunities available from distributed dosing. The practical implication — that the same daily protein intake, redistributed across multiple smaller servings with particular attention to post-exercise and pre-sleep timing — produces measurably superior muscle-building outcomes — is one of the most cost-effective performance nutrition interventions available.
