About Calories Burned
How is it calculated? We use the MET (Metabolic Equivalent of Task) method, which is the gold standard for estimating energy expenditure. The formula is: Calories = MET × weight(kg) × time(hours).
What is MET? MET represents the energy cost of physical activities as a multiple of resting metabolic rate. A MET of 1 equals the energy expended at rest, while a MET of 8 means the activity burns 8 times as many calories as resting.
Factors affecting calories burned:
- Body weight - heavier individuals burn more calories
- Intensity - higher intensity activities have higher MET values
- Duration - longer activities burn more total calories
- Fitness level - trained individuals may be more efficient
- Age and metabolism - individual variations apply
Frequently Asked Questions
How accurate is this calculator?
This calculator uses scientifically validated MET values from the Compendium of Physical Activities. Accuracy is typically within 10-15% for most individuals, though personal factors like fitness level and metabolism can affect results.
Which activities burn the most calories?
High-intensity activities like running fast (MET 14.5), swimming butterfly (MET 11), and jump rope (MET 12.3) burn the most calories per minute. However, the best exercise is one you can sustain consistently.
Should I focus on calories burned for weight loss?
While calories burned is important, sustainable weight loss requires a holistic approach including nutrition, consistent exercise, adequate sleep, and stress management. Use this calculator as one tool in your fitness journey.
