BMR Calculator-Weight Tracker

This BMR Calculator is a simple tool that helps you calculate how many calories your body needs if you were only to rest for the whole day. Based on your age, height, weight, and gender, the Basal Metabolic Rate Calculator returns your BMR score. Keep reading to find out what is BMR, how to calculate BMR, learn more about the Mifflin St Jeor equation and other BMR formulas. We will also show you the differences between calculating BMR for a male and estimating BMR for a female.

For more inquisitive readers we have prepared a brief, theoretical background on how to distinguish Basal Metabolic Rate (BMR) from Resting Metabolic Rate (RMR). We also have written about what factors affect our BMR. Do we have an influence on our BMR? Keep reading to find an answer!

Basal Metabolic Rate Calculator
BMR calculator is short for Basal Metabolic Rate calculator. Basal metabolism is a set of chemical reactions that occur in everyone's body that maintain its living state. We have covered this topic thoroughly in the previous paragraph (What is BMR? – BMR definition). If you know what your Basal Metabolic Rate is, you can estimate the minimal amount of calories you need to take in to live, which helps you to evaluate the total number of calories you should provide to your body daily. Remember, you need to add your energy expenditure (in calories) from other activities like walking, talking, etc, to the number of calories calculated by our BMR calculator. If you add another 10% for digestion you will get your daily Total Energy Expenditure. You may use this information for the basis for your weight loss plan.

But how to use the Basal Metabolic Rate calculator?

Firstly, measure your weight and type it into the Weight field of our calculator.
Secondly, check your height and input it into the Height field.
Now, input your age into the Age field. Please note, that the age value has to be in years.
The last thing to do is to select your sex. In the next paragraph, you will how it slightly changes the Basal Metabolic Rate formula.
Well done! You have correctly followed all the steps, and now our Basal Metabolic Rate calculator will show your minimal caloric intake!
