Clinical context

Calculation steps 1) Total daily energy (TDEE) • Children 3–18 y ─ Boys: EER = 88.5 – 61.9×age + PA×(26.7×weight + 903×height(m)) ─ Girls: EER = 135.3 – 30.8×age + PA×(10×weight + 934×height(m)) • Adults ≥ 19 y ─ Male RMR = 10×weight + 6.25×height(cm) – 5×age + 5 ─ Female RMR = 10×weight + 6.25×height(cm) – 5×age – 161 ─ TDEE = RMR × PA 2) Physical-activity coefficients (Institute of Medicine) Children ♂: 1.00 / 1.13 / 1.26 / 1.42 (sedentary → very) Children ♀: 1.00 / 1.16 / 1.31 / 1.56 Adults ♂: 1.00 / 1.12 / 1.27 / 1.54 / 1.90 Adults ♀: 1.00 / 1.14 / 1.27 / 1.45 / 1.90 3) Macronutrient grams (user-defined %) Proteins = TDEE × (proteins% ÷ 100) ÷ 4 Fats = TDEE × (fats% ÷ 100) ÷ 9 Carbohydrates = TDEE × (carbohydrates% ÷ 100) ÷ 4 Defaults: protein 25 %, fat 25 %, carbohydrates 50 % — editable by the user.
