High-intensity activities like running, swimming, and cycling typically burn the most calories. The exact amount depends on your weight, intensity, and duration of the activity. Running at 10 km/h can burn 10-12 calories per minute for a 70kg person, while walking burns about 4-5 calories per minute.

Our calculator uses MET (Metabolic Equivalent of Task) values, which are standardized measures of energy expenditure. The accuracy is typically within 10-15% for most people. Individual factors like fitness level, body composition, and exercise intensity can affect actual calories burned.

Yes, weight significantly affects calories burned. Heavier individuals burn more calories during the same activity because their bodies require more energy to move. For example, a 90kg person will burn approximately 30% more calories than a 70kg person doing the same exercise for the same duration.

It depends on your goals. If you’re trying to lose weight, you may want to eat only a portion of the calories burned (50-75%) to maintain a deficit. If you’re maintaining weight or trying to build muscle, eating back most or all of the calories can help with recovery and performance.

Higher intensity exercise burns more calories per minute. For example, running at 10 km/h burns more calories than running at 8 km/h. However, you may be able to sustain lower intensity exercise for longer, potentially burning more total calories. The best approach depends on your fitness level and goals.

Yes! This calculator is excellent for weight loss planning. By knowing how many calories you burn during exercise, you can create a calorie deficit by combining exercise with dietary changes. A deficit of 500-750 calories per day typically results in 0.5-0.75 kg of weight loss per week.
