Explanation
Estimates your daily calories using BMR and activity level.
- BMR uses Mifflin–St Jeor:
- Men:
BMR = 10×kg + 6.25×cm − 5×age + 5 - Women:
BMR = 10×kg + 6.25×cm − 5×age − 161 - TDEE (maintenance) =
BMR × activity factor.
This is an estimate. Real maintenance can vary; adjust based on 2–3 weeks of scale trend.
