How are calories burned calculated?

Calories burned are estimated using MET (Metabolic Equivalent of Task) values. MET represents the energy cost of physical activities as a multiple of your resting metabolic rate. The formula is: Calories = MET × weight (kg) × duration (hours).

MET stands for Metabolic Equivalent of Task. A MET of 1 equals your resting energy expenditure. Walking at 3 mph is about 3.5 METs, meaning you burn 3.5 times more calories than at rest.

Why does weight affect calories burned?

Heavier individuals require more energy to move their body, so they burn more calories performing the same activity for the same duration compared to lighter individuals.

Are these estimates accurate?

MET-based estimates provide a reasonable approximation but don't account for individual factors like fitness level, body composition, genetics, or exercise intensity variations. Actual calorie burn may vary by 10–20%.

How can I burn more calories?

Increase exercise intensity, duration, or frequency. High-intensity interval training (HIIT), strength training, and activities that engage multiple muscle groups tend to burn more calories per minute.
