A calories-burned estimate uses activity intensity, body weight and time. It is useful for comparison, but wearable devices and real energy use can differ.
What is a MET?
A MET is a standard activity-intensity value. Higher-intensity activities use a higher MET, so the same activity time can produce a different estimate for a different pace.
Why weight and time matter
The estimate generally rises with body weight and minutes. Keep the time unit consistent and select an activity value that matches the actual session.
Avoid false precision
Use the result to compare workouts rather than to justify exact food intake. Hydration, fitness, technique and terrain can all change real energy use.
- Record the activity and duration.
- Use a realistic intensity value.
- Treat the output as an estimate.
Frequently asked questions
Are calories-burned results exact?
No. MET formulas provide an estimate and cannot capture every personal and environmental factor.
Should I eat back every calorie shown?
Do not treat the result as an exact allowance. Use your broader nutrition plan and professional advice when needed.
