Resting Metabolic Rate

Resting Metabolic Rate (RMR)

What is It?

Your Resting Metabolic Rate, put simply, is the total number of calories your body will burn at rest. Essential functions like breathing, circulating blood and basic brain functions require fuel for energy which accounts for the most basic metabolic activity.

Everyone’s RMR is different. Weight, gender, age and body composition all affect your particular Resting Metabolic Rate. Someone who is large and muscular requires more energy (calories) to maintain functions at rest than someone who is smaller.

RMR is often used synonymously with BMR (Basal Metabolic Rate), however BMR is more correctly used to refer to the result of a direct measurement of a person’s metabolic rate.

Why is It Important?
Knowing your RMR gives you the absolute least number of calories your body requires each day. This is a good starting point when determining your dietary caloric intake for proper nutrition.


The other number that is important is your TDEE or Total Daily Energy Expenditure.

The starting point for this is your RMR. TDEE also includes typical daily activities as well as any exercise performed.

This number is the best point of reference for determining your needed caloric intake based on your goals.
