What is BMR?
Basal Metabolic Rate is the number of calories your body needs to maintain basic life-sustaining functions while at complete rest.
Mifflin-St Jeor Formula (Male)
BMR = 10 x weight(kg) + 6.25 x height(cm) - 5 x age + 5
Example Calculation
A 30-year-old, 170 lbs, 70 inches tall.
- 01Weight: 77.1 kg, Height: 177.8 cm
- 02BMR = 10(77.1) + 6.25(177.8) - 5(30) + 5
- 03= 771 + 1,111.25 - 150 + 5 = 1,737 cal/day
