How We Calculate Calories Burned
This calculator utilizes the MET (Metabolic Equivalent of Task) system, a scientific standard used to measure the energy expenditure of physical activities. One MET is defined as the amount of oxygen consumed while sitting at rest.
Our tool uses the following standardized formula:
Calories = (MET × 3.5 × weight_kg / 200) × duration_minutes
Why use the MET system?
The MET system allows us to standardize energy expenditure across different activities. Whether you are walking on a treadmill or lifting heavy weights, the intensity of your effort is captured through the MET value, providing a much more accurate estimate than generic "calories per hour" charts.
Frequently Asked Questions
- How accurate is this estimate? While the MET system is highly regarded, individual factors like genetics, metabolic rate, and fitness level can cause slight variations.
- Should I track these calories in my daily diet? Many fitness enthusiasts use this to understand their activity levels, but be mindful that exercise calorie burns can sometimes be overestimated.
- What is the best way to improve calorie burn? Increasing the duration or the intensity (the MET value) of your chosen activity is the most effective way to improve total energy expenditure.
