The Science of Calorie Burning

Understanding how your body burns energy is key to weight management. This calculator uses the MET (Metabolic Equivalent of Task) formula, widely used by health professionals:

Calories Burned = MET × Weight (kg) × Duration (hours)

Why does this matter?

Weight Management: To lose 1 lb of fat, you typically need a deficit of ~3,500 calories. Knowing your burn rate helps you plan.
Activity Selection: Different exercises burn calories at vastly different rates. Running burns roughly twice as much as walking in the same time.
Intensity: "Vigorous" versions of exercises often double the MET value. Increasing intensity is often more time-efficient than increasing duration.
