Formula + logic
1) Convert weight to kilograms (kg).
2) Minimum protein = 0.8 × weight(kg).
3) Recommended protein = activity-based factor × weight(kg).
4) High protein = (recommended factor + 0.4) × weight(kg), capped at 2.2 g/kg.
5) CDC line uses estimated calories (Mifflin-St Jeor) and converts 10–35% of calories to grams (÷4).
