- 1Step 1: Calculate BMR using Mifflin-St Jeor: Men: 10W + 6.25H − 5A + 5, Women: 10W + 6.25H − 5A − 161
- 2Step 2: Multiply BMR by activity factor (1.2 sedentary to 1.9 very active)
- 3Step 3: Adjust for goal: −500 kcal/day = ~0.5kg loss/week, +500 = ~0.5kg gain/week
- 4Step 4: Calculate macros: protein ~2.2g/kg, fat ~25% of kcal, remainder as carbs
