FAQ
How is calorie burn calculated?
The calculator estimates energy use from the activity MET value, body weight and exercise duration.
Are calorie burn calculators exact?
No. They provide estimates. Actual energy expenditure varies with intensity, fitness, age, body composition and other factors.
What does MET mean?
MET is a standardized measure of activity intensity relative to resting energy expenditure.
Formula and method
kcal = MET × 3.5 × kg ÷ 200 × minutes.
Activity calories include resting energy. Results are estimates; TDEE is for adults. The −500 and +300 kcal variations are arithmetic scenarios, not personalized targets.
