BMR Calculator

Calculate your Basal Metabolic Rate - the number of calories your body burns at rest.

Frequently Asked Questions (FAQ) - BMR Calculator

What is BMR and why is it important?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions such as breathing, circulation, and cell production while at rest. Knowing your BMR helps you manage weight and energy needs effectively.

How is BMR calculated?

BMR is calculated using your weight, height, age, and gender. Common formulas include the Harris-Benedict and Mifflin-St Jeor equations, both designed to estimate calorie requirements for maintaining vital body functions.

What is the difference between BMR and RMR?

BMR (Basal Metabolic Rate) measures energy used in a completely rested state, while RMR (Resting Metabolic Rate) measures energy used at rest but under less strict conditions. RMR is usually slightly higher than BMR.

How can I use my BMR to lose or gain weight?

Once you know your BMR, you can adjust calorie intake based on your goals. To lose weight, consume fewer calories than your total daily energy expenditure (TDEE). To gain weight, eat slightly above your TDEE.

Does BMR change with age or activity?

Yes. BMR tends to decrease with age due to muscle loss and hormonal changes. It can also vary based on muscle mass, body composition, and overall physical activity level.

How can I increase my BMR naturally?

You can boost your BMR by increasing muscle mass through strength training, staying active, eating enough protein, and maintaining consistent sleep patterns and hydration.
