You might be wondering, what is BMR all about? Well, it’s definitely a term that’s thrown around a lot but not often explained in detail. Your BMR number tells you how many calories your body needs to survive.  

Up next we’re going to tell you how to calculate BMR and also answer questions like what does BMR stand for and how do I improve my BMR? Once you learn about your BMR, you’re going to be able to get a much better handle on your calorie needs and weight goals.

What Is BMR?

When we break down the the BMR meaning from its acronym we learn it means Basal Metabolic Rate. That is the number of calories your body burns making basic functions in your body happen while you are at rest.

These basic functions include things like breathing, blinking and cell regeneration. Regardless of what the function is, it requires energy to happen, however the amount of energy each function requires is based on your age, height, weight, and sex.

The Difference Between BMR And TDEE

Your BMR is a vital component of Total Daily Energy Expenditure (TDEE). Your BMR represents the number of calories your body needs to live. Your TDEE number represents the number of calories you use for activities added to your BMR.

Knowing what your TDEE number is can help you lose weight. That’s because you’ll learn how many calories you burn each day on average and then you can reduce your consumption or increase your activity to get the weight you want.

Basal Metabolic Rate Vs Resting Metabolic Rate

There is not a huge difference between your BMR and your Resting Metabolic Rate (RMR), which is why the two terms are often used interchangeably. However, we can point to a slight technical difference.

Both numbers represent the calories your body uses at rest, however, RMR also includes the number of calories you need for activities at rest like getting up to go to the bathroom and eating.

Body composition affects BMR.
