Calculate your Basal Metabolic Rate (BMR) to estimate the minimum calories your body needs at rest to perform essential functions.
This is the estimated minimum number of calories your body needs each day at rest to maintain basic body functions.
Note: BMR is different from your total daily calories. It only includes calories required at rest. To know your total daily calories, use our TDEE Calculator.
BMR is calculated using predictive equations based on your age, sex, height, and weight. The most commonly used formula is the Mifflin-St Jeor Equation.
View formula & details →Yes, you can support a higher BMR by building muscle, staying active, eating enough protein, sleeping well, and maintaining a healthy body composition.
Tips to increase BMR →Use your BMR as a baseline to understand your body's minimum calorie needs.
Add activity level to find your total daily calorie needs (TDEE).
To lose weight, aim for a calorie deficit below your TDEE, not below your BMR.
Eating too few calories (below BMR) for long periods may lead to fatigue, nutrient deficiencies, and muscle loss.
Confusing BMR with TDEE
Eating below BMR for long periods
Ignoring body composition
Not updating calculations over time
Relying only on BMR for weight loss
A “good” BMR does not have one specific value. BMR varies based on factors such as age, sex, weight, height, and muscle mass.
A higher BMR is not necessarily better. Resting energy needs naturally differ between individuals based on body composition and other factors.
Muscle mass can influence resting energy requirements because muscle tissue requires energy to maintain.
Yes. BMR can change over time as factors such as age, body composition, muscle mass, lifestyle, and health change.
BMR estimates depend on several individual factors, including age, sex, height, weight, and muscle mass. A calculator provides an estimate rather than a direct measurement.
BMR is the minimum calories your body needs at rest.
It is different from RMR and TDEE.
Your BMR depends on several factors like age, sex, weight, and muscle mass.
It can change over time.
Use BMR as a starting point, not the only guide.
Even while sleeping, your body burns calories to keep you alive and functioning.
Your brain uses about 20% of your total daily calories, even when you're at rest!
