Frequently Asked Questions
How are calories burned calculated?
We use the MET (Metabolic Equivalent of Task) formula: Calories = MET × weight in kg × duration in hours. MET values come from the Compendium of Physical Activities and represent energy use relative to rest.
Why does weight affect calories burned?
Heavier people burn more calories doing the same activity because it takes more energy to move a larger body mass. This is why weight is a direct multiplier in the calorie burn formula.
How accurate is this calculator?
MET-based calculations are a reasonable estimate but individual variation is significant. Actual burn depends on fitness level, body composition, terrain, and intensity. Heart rate monitors with chest straps offer more personalised estimates.
What is a MET value?
MET stands for Metabolic Equivalent of Task. A MET of 1 equals energy burned at rest. Walking is about 3.5 MET, jogging 7.0, and fast running 11+. Higher MET = more calories per minute.
How many calories do I need to burn to lose 1 lb?
A pound of fat contains roughly 3,500 calories. To lose 1 lb per week, you need a daily deficit of 500 calories through eating less, moving more, or both. Our calorie deficit calculator can help you plan this.
