How it works
Enter the requested values, check the units, then run the TDEE Calculator for a copyable informational estimate.
The tool works by multiplying a Mifflin-St Jeor resting-energy estimate by the selected activity assumption. The result is a general estimate that cannot account for every individual factor and does not replace a clinician. Inputs stay in the browser.
Examples
Practical example
The page shows both resting energy and the activity-adjusted estimate.
Method and source
Uses the Mifflin-St Jeor resting-energy equation described in PubMed PMID 2305711.
