Thermodynamic Buffer Proof

With 6.5 kg of added lean muscle tissue, daily resting metabolic rate expands by +235 kcal (direct organ/muscle turnover) and physical work capacity drives an extra +610 kcal in NEAT, EAT, and substrate thermogenesis. Total daily expenditure increases by ~845 kcal/day.
Direct Lean Tissue Resting Burn: +85 kcal/day
Systemic Metabolic Remodeling: +150 kcal/day
Resistance Work Capacity (EAT+NEAT): +510 kcal/day
Thermic Effect of Food (TEF): +100 kcal/day
Total Measured TDEE Elevation: +845 kcal/day
