BMR Calculator

BMR, or Basal Metabolic Rate, is an essential measure of the number of calories your body needs to maintain basic physiological functions at rest, such as breathing, circulation, cell production, and nutrient processing. Understanding your BMR is crucial for creating a tailored nutrition and exercise plan, especially when aiming to manage weight, increase energy levels, or enhance overall fitness. This is because your BMR accounts for the largest portion of your daily caloric needs.

The Mifflin-St Jeor equation is a widely recognized method for estimating BMR. It considers factors such as age, sex, weight, and height, making it more precise than older methods like the Harris-Benedict equation. Developed in the 1990s, the Mifflin-St Jeor equation has been validated by numerous studies and is often recommended for its accuracy in modern populations.

Note: enter your height in inches (imperial) or in centimeters (metric).
