Calories Burned Calculator

How MET Values Work

• 1 MET = energy cost of sitting quietly (about 1 calorie per kg per hour)
• 3 METs = activity uses 3 times the energy of sitting quietly
• 6 METs = activity uses 6 times the resting energy expenditure
• Higher MET values indicate more intense, calorie-burning activities

Calculation Formula

This formula accounts for the fact that heavier people burn more calories during the same activity, and longer duration increases total calorie burn proportionally.

Light Intensity (1.6-2.9 METs)

Activities that require minimal effort and can be done for extended periods. Examples: slow walking, light housework, gentle yoga. Good for recovery and maintaining daily activity.

Moderate Intensity (3.0-5.9 METs)

Activities that noticeably increase heart rate and breathing but allow you to carry on a conversation. Examples: brisk walking, recreational cycling, swimming laps. Meets health guidelines for regular exercise.

Vigorous Intensity (6.0-8.7 METs)

Activities that significantly increase heart rate and breathing, making conversation difficult. Examples: running, competitive sports, high-intensity fitness classes. Provides excellent cardiovascular benefits.

Very Vigorous Intensity (≥8.8 METs)

High-intensity activities that can only be sustained for short periods. Examples: running >8 mph, competitive cycling, intense interval training. Reserved for well-conditioned individuals.

Individual Factors

• Body Weight: Heavier individuals burn more calories per minute
• Body Composition: More muscle mass increases calorie burn
• Fitness Level: Fit individuals may burn calories more efficiently
• Age: Metabolic rate generally decreases with age
• Gender: Men typically burn slightly more calories than women

Environmental and Activity Factors

• Temperature: Extreme heat or cold can increase energy expenditure
• Terrain: Hills, sand, or uneven surfaces increase calorie burn
• Intensity: Working harder within an activity burns more calories
• Equipment: Carrying weight or using resistance increases energy cost

For Weight Management

• Create a caloric deficit by burning more calories than you consume
• 3,500 calories equals approximately 1 pound of body weight
• Combine calorie burn with dietary changes for sustainable weight loss
• Track both calories burned and calories consumed for accurate balance

For Fitness Goals

• Aim for 150 minutes of moderate activity or 75 minutes of vigorous activity weekly
• Mix different intensities and activities for comprehensive fitness
• Use calorie burn to track progress and set realistic goals
• Higher intensity activities provide more benefits in less time

Activity Selection Tips

• Choose activities you enjoy to maintain long-term consistency
• Vary activities to prevent boredom and work different muscle groups
• Consider time constraints - vigorous activities burn more calories per minute
• Include both cardio and strength training for optimal health benefits
