Calculate activity energy expenditure using metabolic equivalent (MET) values.
Calories-burned calculators estimate exercise energy expenditure from body weight, activity intensity (MET), and duration.
MET-based estimates are useful for planning but should be calibrated against real body-weight trend data over time.
Choose the closest movement and intensity profile.
Input current weight in kg or lb.
Provide minutes of active movement time.
The tool assigns or accepts manual MET intensity.
Read total estimated kcal for the session.
Use estimates conservatively when adjusting intake.
Calories = MET x 3.5 x weight(kg) / 200 x minutes
The equation converts MET intensity into oxygen-based caloric expenditure scaled by body weight and exercise duration.
Calories = 8.3 x 3.5 x 70 / 200 x 30
Estimated burn: about 305 kcal
Calories = 4.3 x 3.5 x 82 / 200 x 45
Estimated burn: about 279 kcal
Calories = 10 x 3.5 x 65 / 200 x 60
Estimated burn: about 683 kcal
