How it works
Calories = MET × weight in kilograms × hours. MET (metabolic equivalent of task) measures intensity relative to rest: sitting is about 1 MET, walking about 3.5, running about 9.8 at a moderate pace.
Frequently asked questions
Why is this only an estimate?
MET values are averages. Your speed, grade, fitness and efficiency all shift the real number.
Does faster running burn more per mile?
Per minute, yes — a higher MET. Per mile the difference is smaller, because you finish sooner.
Should I eat back these calories?
That depends on your goal. Talk to a professional before using exercise calories to plan a diet.
