Understanding your calculation
Method, example and limitations
How the calculation works
Activity expenditure is estimated from the selected activity intensity, body mass and duration. MET-based models express activity cost relative to a reference resting rate.
Example to check
Using the common approximation kcal = MET × kg × hours, an activity assigned 4 METs for a 70 kg person over half an hour is about 140 kcal.
Before using the result
Different MET conventions can give slightly different totals. Gross expenditure includes resting energy; net expenditure excludes it. Fitness, terrain, technique and intensity vary between people.
