BMR Formula (Mifflin-St Jeor)
Expression: BMR = 10×W + 6.25×H − 5×A + s
Mifflin-St Jeor estimates basal metabolic rate — calories burned at complete rest. W=weight(kg), H=height(cm), A=age, s=+5(male) or −161(female). Multiply by activity factor for TDEE.
Example: Female, 60 kg, 165 cm, 28 years
W=60, H=165, A=28, s=−161
BMR = 600 + 1031.25 − 140 − 161 = 1330.25
Result: BMR ≈ 1,330 calories/day
