Basal Metabolic Rate (BMR) Calculator

To live is to burn fuel!
No matter what you are doing, you are expending energy. Your basal metabolic rate, or BMR, is the total number of calories your body burns to carry out normal functions such as digestion, circulations and body temperature regulation.

This calculator lets you estimate the number of calories your body burns when you are resting and the number of calories you need to maintain your current weight. To lose weight, you must create a calorie deficit by eating less and exercising more.

BMR changes over time
You might have noticed that maintaining your weight gets harder with every passing year. At one time, you probably were able to eat just about anything you wanted. But metabolism slows with age and your body no longer burns off as much energy.
