MET (Metabolic Equivalent of Task) is a measure of the energy cost of physical activities. One MET equals the energy expended while sitting quietly (approximately 1 kcal/kg/hour). A 4 MET activity expends 4 times the energy used by the body at rest.

This calculator provides estimates based on average MET values and uses the standard formula: Calories Burned = MET × Weight (kg) × Time (hours). Individual results may vary based on factors like fitness level, age, gender, and exercise intensity.

A person who weighs more will burn more calories doing the same activity because it requires more energy to move a heavier body. This is why the calculator takes your weight into account when calculating calories burned.

METs are used to compare the intensity of different activities and estimate energy expenditure. They help in exercise prescription, research, and public health guidelines. The CDC and WHO use METs to classify physical activity intensity levels.

You can increase calories burned by: 1) Increasing exercise duration, 2) Choosing higher intensity activities with higher MET values, 3) Adding intervals of high-intensity exercise, 4) Incorporating strength training to build muscle mass, and 5) Staying consistent with your exercise routine.

Muscle tissue is more metabolically active than fat tissue, meaning it burns more calories even at rest. People with higher muscle mass typically burn more calories during both exercise and rest periods, contributing to a higher daily caloric expenditure.

Yes, factors like temperature, humidity, altitude, and terrain can affect how many calories you burn. For example, exercising in cold weather or at high altitudes typically burns more calories as your body works harder to maintain its core temperature or adapt to lower oxygen levels.
