What is REE?
Resting energy expenditure is the energy your body uses for essential functions like breathing, circulation, body temperature, and cell repair while at rest.
REE is closely related to BMR. In everyday calorie calculators, the terms are often used near each other because both describe the resting baseline before activity is added.
REE vs TDEE
- REE is the resting baseline.
- BMR is a similar basal estimate used by many equations.
- TDEE adds activity, exercise, and movement.
- Daily calorie targets usually start with BMR or REE, then apply an activity multiplier.
Why this matters for tracking
If REE is the foundation, your daily routine is the multiplier. Coach Ivy helps you test the estimate by tracking meals and progress consistently.
