Worked Example: BMR
Given:
- weight = 70
- height = 175
- age = 30
- sex = 1
- 10 × 70 kg = 700
- 6.25 × 175 cm = 1093.75
- 5 × 30 years = 150
- BMR = 700 + 1093.75 − 150 + 5 = 1648.75 kcal/day
Answer: 1648.75
Frequently Asked Questions
What is the BMR formula?
BMR = 10W + 6.25H − 5A + 5 (men) or − 161 (women). Basal Metabolic Rate — calories your body burns at complete rest (Mifflin-St Jeor). Sex: 1 = male, 2 = female.
How do I calculate BMR?
Enter Weight (weight), Height (height), Age (age), Sex (1 = male, 2 = female) (sex) into the calculator. It applies BMR = 10W + 6.25H − 5A + 5 (men) or − 161 (women) and shows every step of the working.
