Formula and method
Calories are estimated with MET values (Metabolic Equivalent of Task): calories = MET × weight (kg) × duration (hours).
Worked example
Running at a moderate pace (about 9.8 MET) for 30 minutes at 70 kg: 9.8 × 70 × 0.5 ≈ 343 kcal.
Tips
- Wearables and machines also estimate calories and can differ by 20 percent or more.
- Do not "eat back" every burned calorie; estimates tend to run high.
