FAQ
Which formula is this?
Mifflin-St Jeor. Male BMR = 10×kg + 6.25×cm − 5×age + 5. Female uses −161 instead of +5. Daily calories = BMR × activity.
Is this medical advice?
No. It is a common estimate. Needs vary with body composition, health, and goals.
How do I lose or gain weight?
A rough rule is ±500 kcal/day ≈ 0.5 kg/week. That is not a prescription: check with a clinician if you are changing diet.
