The number of calories burned while running depends on your weight, speed, and duration. As a general rule, you burn approximately 1 calorie per kilogram of body weight per kilometer run. For example, a 70kg person running 5km will burn roughly 350 calories. Running at a faster pace increases the intensity (MET value), which slightly increases the calories burned per minute.

Yes, running burns significantly more calories per minute than walking because it requires more energy to lift your body weight off the ground with each stride. However, if you walk for a longer duration to cover the exact same distance as a run, the total calories burned will be very similar, though running still yields a slightly higher total due to the ‘afterburn’ effect (EPOC).

Running calorie calculators using MET (Metabolic Equivalent of Task) values are generally accurate to within ±10% for most runners. However, individual factors like running efficiency, terrain, wind resistance, heart rate, and muscle mass can affect actual energy expenditure. They are excellent for tracking trends and estimating daily energy needs.

Yes, running faster increases your MET value, meaning you burn more calories per minute. However, the total calories burned over a fixed distance remain relatively constant regardless of speed. The main benefit of running faster is that you cover the distance in less time, achieving a higher caloric burn rate and triggering a higher ‘afterburn’ effect post-exercise.

A MET is a unit used to estimate the energy cost of physical activity. 1 MET is defined as the energy you expend sitting at rest. Running typically ranges from 7.0 METs (light jogging) to 16.0 METs (sprinting). The formula to calculate calories per minute is: (MET × 3.5 × Weight in kg) / 200.

For an average-sized adult, running a 5K (3.1 miles) typically burns between 300 and 400 calories. A 60kg person will burn around 310 calories, while an 80kg person will burn approximately 415 calories, assuming a moderate running pace of 6:00 min/km (10 min/mile).

Absolutely. Running is one of the most effective cardiovascular exercises for weight loss because it burns a high number of calories in a short amount of time. To lose weight, you must maintain a caloric deficit. Combining regular running with a balanced, calorie-controlled diet is the most sustainable way to lose weight and keep it off.

The calorie burn is very similar, but outdoor running typically burns about 3-5% more calories due to wind resistance and variations in terrain. To perfectly simulate outdoor running conditions on a treadmill, you can set the incline to 1%. However, for general fitness tracking, the difference is negligible.
