What is BMR ?
The Basal Metabolic Rate (BMR) is the number of calories that your body needs to maintain basic bodily functions, such as breathing and digestion. This is the amount of calories you need to consume each day when you do not do any physical activities.

Understanding your BMR can help you make more informed decisions about your diet and lifestyle. Knowing how many calories your body needs to function and how your daily activities affect your calorie needs is a key part of maintaining a healthy lifestyle.
How is BMR Calculated?
There are several different formulas used to calculate BMR for both men and women. The Mifflin-St Jeor Equation is considered the most accurate equation to calculate BMR:
Mifflin-St. Jeor Equation
The Mifflin-St. Jeor Equation is considered one of the most accurate for estimating BMR. This is the formula we use in our calculator:
- Men: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5
- Women: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161
The resulting value is the number of calories a person would burn each day if they were at rest all day.
Harris-Benedict Equation
The Harris-Benedict Equation is another commonly used formula for estimating BMR:
- Men: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) - (5.677 * age in years)
- Women: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) - (4.330 * age in years)
Katch-McArdle Formula
The Katch-McArdle Formula can be more accurate for people who are leaner and have more muscle mass:
BMR = 370 + (21.6 * Lean Body Mass(kg) )
Where Lean Body Mass = (Weight(kg) * (1 - (Body Fat % / 100)))
