Calories Burned Calculator

MET stands for Metabolic Equivalent of Task. A MET of 1 equals resting energy expenditure (approximately 1 kcal/kg/hour). An activity with a MET of 8 burns 8 times more energy than resting.

The MET-based formula provides an estimate with an accuracy of approximately +/- 20%. Actual calories burned vary based on fitness level, age, body composition, exercise intensity, and environmental conditions.

Yes. Heavier individuals burn more calories for the same activity because more energy is required to move a larger mass. This is reflected in the formula where weight is a direct multiplier.

It depends on your goals. For weight loss, eating back all exercise calories typically negates the deficit. For performance or maintenance, replacing some calories supports recovery. Aim to eat back 50-75% if needed.

High-intensity activities like running, jump rope, and vigorous cycling burn the most calories per hour. However, lower-intensity activities done for longer can also burn significant total calories.

Yes. Muscle tissue is metabolically active and burns more calories than fat both at rest and during exercise. Building muscle through resistance training increases calorie burn during workouts and at rest.
