FAQ
What is a MET?
Metabolic Equivalent of Task—energy cost relative to sitting (1 MET). Calories = MET × weight (kg) × hours.
Why does my watch show different numbers?
MET math assumes average intensity; watches use heart rate. Both carry ±10–20% error—use them for trends.
How much exercise burns 1 kg of fat?
About 7,700 kcal—roughly 3+ weeks of daily 30-minute runs for a 70 kg adult. Combine with diet changes.
