What does an REE test measure?
Relax in a quiet setting and breathe normally through a mask or under a canopy. Indirect calorimetry uses oxygen consumption and carbon dioxide production to estimate your resting energy expenditure.
REE is not your total daily calorie requirement or a minimum safe food intake. A daily target also requires assessment of activity, goals and individual circumstances.
Who might find it useful?
Adults planning nutrition or managing weight who want a measured starting point. You do not need to be an athlete or a Gymnasia member.
The test itself does not cause weight loss or guarantee results. It is one tool for nutrition planning and is not essential for everyone.
How to prepare
- 01Do not eat for at least 4 hours before the test.
- 02Avoid caffeine and vigorous exercise for 12 hours before the test.
- 03Arrive rested. Confirm preparation suitable for you with the team beforehand.
If fasting is difficult because of a health condition, or you take medication, discuss preparation with the team and your clinician if needed. Do not stop prescribed medication on your own.
