Macro Splits at Maintenance

Daily macronutrient targets for common diet styles. 1g protein = 4 kcal, 1g carbs = 4 kcal, 1g fat = 9 kcal.

About TDEE

Total Daily Energy Expenditure (TDEE) is the number of calories your body burns per day, combining:

  • BMR (Basal Metabolic Rate): ~60–70% of TDEE — calories burned at complete rest just to stay alive.
  • TEF (Thermic Effect of Food): ~10% — calories burned digesting food. Higher for protein.
  • NEAT (Non-Exercise Activity Thermogenesis): fidgeting, walking, posture — highly variable.
  • EAT (Exercise Activity Thermogenesis): deliberate workouts.

Mifflin-St Jeor Formula

Male: 10·W + 6.25·H − 5·A + 5
Female: 10·W + 6.25·H − 5·A − 161

W = kg, H = cm, A = years

Katch-McArdle Formula

BMR = 370 + 21.6 × LBM
(LBM = weight × (1 − bodyfat%/100))

Requires body fat % but more accurate for lean individuals.

Educational tool. Actual calorie needs can vary ±15% from predicted values due to genetics, metabolic adaptation, NEAT differences, and measurement error. Track 2–3 weeks of weight changes to refine estimates.
