Your body requires energy (calories) for all functions, from basic survival to intense physical activity. This calculator helps you understand how exercise contributes to your total energy expenditure and how it can be used for weight management.
The calculator breaks down your energy expenditure into two main components:
MET (Metabolic Equivalent of Task) is a measure of the energy cost of physical activities. One MET is defined as the energy expended while sitting at rest, which is approximately 1 calorie per kilogram of body weight per hour.
Activities are assigned MET values based on their intensity:
The calculator adjusts MET values based on the intensity (speed/level) you select, providing a more accurate estimate of calories burned during your specific workout.
Weight loss occurs when you create a calorie deficit—burning more calories than you consume. The general guideline is that 3,500 calories equals approximately one pound of fat, though this is a simplification and actual results vary based on individual factors.
This calculator estimates how long it will take to reach your weight loss goal based on the calorie deficit created by your exercise routine alone. For more effective weight management, consider combining exercise with dietary changes.
For sustainable weight loss, aim for a moderate deficit of 500-1000 calories per day, which typically results in 1-2 pounds of weight loss per week. Rapid weight loss is generally not recommended as it can lead to muscle loss, metabolic adaptation, and is harder to maintain long-term.
While this calculator provides useful estimates, several factors can affect actual results:
The Body Fat Burn Calculator is a tool designed to help you understand how physical activity contributes to weight loss. It calculates the calories burned during specific activities and estimates how long it would take to reach a weight loss goal through exercise alone.
Unlike general calorie calculators, this tool focuses specifically on the relationship between exercise, energy expenditure, and fat loss, providing a realistic timeline for achieving your goals.
This calculator uses several established scientific principles:
While these principles provide a solid foundation for estimation, individual results may vary based on factors like genetics, body composition, and exercise efficiency.
The calculator provides several key pieces of information:
For optimal results, consider these recommendations:
