Resting Metabolic Rate (RMR) Testing

Resting Metabolic Rate (RMR) Testing

Cardiometabolic Health

How many calories do you actually burn at rest? Let’s measure it.

Your Resting Metabolic Rate (RMR) is the number of calories your body burns just to stay alive—before you account for exercise, walking, or even digesting food. It’s a crucial number if you want to improve energy, manage weight, prevent burnout, or simply understand your body better.

Sperity uses clinical-grade breath analysis to give you an accurate metabolic baseline and practical, personalized recommendations you can use every day.
