Frequently asked questions
How accurate is this estimate?
MET-based estimates are within 10-20% for most people. Actual burn varies with fitness level, age, terrain, and effort intensity.
What is a MET value?
MET (Metabolic Equivalent of Task) measures how hard your body is working. Sitting is ~1 MET; walking is ~3.5 MET; running is ~10 MET.
Should I eat back exercise calories?
Depends on your goals. Many nutrition experts suggest eating back only 50-75% of exercise calories to account for estimation error.
