Episode notes
Post-Workout Timing Is Not Critical
- The classic 30–60 minute 'anabolic window' is mainly based on overnight‑fasted, glycogen‑depleted studies and doesn't generalize to normal life.
- If total daily protein and calories are met, immediate pre/post workout timing shows no meaningful advantage for muscle growth.
Err On The Side Of More Protein
- Favor slightly higher protein rather than under-consuming because protein supports lean mass and satiety.
- You rarely waste protein; most diets use it efficiently and it helps with fat loss and hunger control.
Collagen Targets Connective Tissues
- Collagen differs from whey: it is rich in glycine, proline and hydroxyproline and targets connective tissues.
- Collagen supplementation (10–20 g/day) can benefit skin, joints and bone and should count toward daily protein.
