BMR Calculator (Basal Metabolic Rate)
Calculate your Basal Metabolic Rate using the Mifflin-St Jeor and Katch-McArdle equations.
Mathematical Formula
BMR Male = 10*weight + 6.25*height - 5*age + 5
Overview & Explanation
Basal Metabolic Rate is the total number of calories your body needs to maintain basic life-sustaining function at rest.
How It Works
- Evaluates Mifflin-St Jeor metabolic factors for age, weight, and height.
Practical Applications
- Calorie deficit planning.
- Nutrition plan creation.
Male 30y, 70kg, 175cm
Calculate Mifflin-St Jeor BMR.
1
Apply weight factor
10 * 70
= 700
2
Apply height factor
6.25 * 175
= 1093.75
3
Apply age factor and constant
700 + 1093.75 - 150 + 5
= 1649 kcal/day
