🧬 Post-workout protein: 0.25–0.40 g/kg or 20–40g per dose (ISSN)
⚡ Leucine trigger: 1–3g leucine activates mTORC1 MPS pathway
🍞 High-MET carbs: 1.0–1.2 g/kg/hr for glycogen recovery
😴 Pre-sleep protein: 30–40g casein sustains overnight MPS
📅 Daily protein: 1.4–2.0 g/kg; 2.3–3.1 in deficit (ISSN)

⚠️ Disclaimer: Calorie estimates are derived from population-average MET values (2024 Adult Compendium of Physical Activities, Herrmann et al.) and represent approximations. Individual energy expenditure varies by fitness level, body composition, age, sex, altitude, and ambient temperature. EPOC estimates are approximate (+5–12%). Nutritional recommendations follow ISSN Position Stand guidelines and are general guidance, not personalised medical or dietetic advice. Consult a registered dietitian or sports nutritionist for individualised prescriptions. Designed for adults aged 19–59 per the scope of the 2024 Adult Compendium.
