01
What is Resting Energy?
Resting Energy Expenditure (REE) is the amount of energy your body burns while at complete rest. It's the energy needed to maintain basic life functions like breathing, circulation, and cell production.
02
Macronutrient Distribution
Resting-energy equations estimate a population average. The result card includes a small uncertainty range to make that limitation visible instead of presenting one number as exact.
03
Using This Information
REE is not a daily calorie target because it excludes normal movement and exercise. Use the TDEE calculator for a broader daily estimate.
Method and sources
Method: Mifflin–St Jeor resting energy equation.
Supported population: Adults age 18 to 100 using the equation's sex-specific constant.
- The result represents resting use only
- The displayed range is context, not a measured confidence interval
Frequently asked questions
How is the Resting energy estimate calculated?

What are the limitations of this Resting energy estimate?
Resting energy is not a daily intake recommendation and varies with body composition and health status.
