Frequently Asked Questions
What is MET?
Metabolic Equivalent of Task. MET 1 = sitting still. Walking = 3-4 MET, cycling = 6-8, running = 8-12, swimming = 6-10. Higher MET = more intense.
How accurate is this?
MET-based estimates are within 15-20% for most people. Actual burn depends on intensity, fitness level, body composition, and environmental factors.
How many calories to lose 1 pound?
Roughly 3,500 calories equals 1 pound of fat. A 500 cal/day deficit through diet and exercise produces about 1 lb/week loss.
Does exercise after-burn count?
Yes — EPOC (excess post-exercise oxygen consumption) can burn 6-15% additional calories after intense exercise. This calculator estimates direct burn only.
Is the Calories Burned Calculator free to use?
