Luc van Loon

Luc van Loon is a researcher in the fields of exercise science, sports nutrition, and muscle metabolism. His published research focuses on dietary protein requirements, muscle protein synthesis rates, and the metabolic effects of exercise. He also investigates the impacts of amino acid supplementation and resistance training on muscle mass and recovery across diverse populations, including athletes, older adults, and clinical patients.

Ingesting 20 grams of protein induces an increase in muscle protein synthesis that peaks around 3 hours post-meal and wears off in approximately 5 to 6 hours.

"so if you ingest 20 grams of protein, you see a strong, robust increase in muscle protein synthesis that peaks around three hours after a meal, and then it wears off in about five, six hours." (said at 1:12:54)

Clinical tracer studies in healthy adults show that oral protein intake stimulates a transient increase in muscle protein synthesis that peaks within approximately 45 to 90 minutes postprandial and returns to baseline rates by approximately 90 to 180 minutes (the 'muscle-full' effect), even while extracellular amino acid concentrations remain elevated. The claim that synthesis peaks at 3 hours and persists for 5 to 6 hours after protein ingestion is contradicted by human physiological measurements.
