The full read
Once the motivational packaging is stripped away, the implicit claim — that eating enormous amounts of protein builds an outlier physique — is clearly overstated. The reference meta-analysis (Morton et al. 2018, 49 trials, 1,863 participants) puts the plateau for lean-mass gains around 1.6 g/kg/day, with the upper confidence bound at 2.2 g/kg/day. Even for a 130kg bodybuilder, that tops out around 285g/day — less than half of the 600g claimed. Beyond that plateau, excess nitrogen is simply oxidized for energy or excreted, with no added benefit to muscle synthesis; a recent isotope-tracer study (Trommelen et al. 2023) found no per-meal ceiling on protein utilization, but that doesn't overturn the daily plateau established by lean-mass trials. The number mostly serves the champion's legend rather than a realistic or necessary recommendation — training, genetics, and decades of practice explain a physique like Ronnie Coleman's far more than protein quantity alone.
