Calorie Burn Calculator
Estimate calories burned per activity based on your weight and duration
// MET Values
This calculator uses MET (Metabolic Equivalent of Task) values. Formula: Calories = MET × weight(kg) × duration(hours). MET of 1 = sitting at rest.
// Exercise vs Diet
You can't outrun a bad diet. Running 30 min burns ~300 cal — one slice of pizza. Weight management is 80% diet, 20% exercise. But exercise has huge health benefits beyond calories.
// EPOC Effect
High-intensity exercise creates an "afterburn" (EPOC) where you continue burning calories for hours after. HIIT and weight training have a stronger afterburn than steady-state cardio.
// Accuracy Note
Calorie estimates vary by fitness level, body composition, and intensity. These are approximations. Heart rate monitors and fitness trackers provide more personalised readings.
