Experts pressure-tested common protein claims and found many still under-supported
A February 2025 Indiana University workshop asked over twenty international experts to pressure-test propositions about dietary protein: methodological limitations, ‘optimal’ intake for muscle synthesis, accretion, growth and repair, needs during weight loss, anabolic thresholds and potentially harmful high intakes. Experts rated evidence from strong support to sufficient to rule out. Most propositions required more research because studies lacked rigor, sample size, duration or relied on surrogate outcomes.
