Estimated BMR
1,698.75 kcal/day
Maintenance calories
2,335.78 kcal/day
Working
Estimate basal metabolism from age, sex, height, and weight, then multiply by the selected activity factor.
Estimated BMR: 1,698.75 kcal/day
Step 1Select sex constant
Male constant = 5
Step 2Estimate BMR
BMR = 10 x 75 + 6.25 x 175 - 5 x 30 + 5 BMR = 1,698.75 kcal/day
Step 3Apply activity factor
1,698.75 x 1.38 = 2,335.78 kcal/day
Further explanation
BMR is the approximate energy used at rest. Maintenance calories add an activity multiplier to estimate a full day.
