MET System Explained
What is a MET?
MET (Metabolic Equivalent of Task) represents the ratio of working metabolic rate to resting metabolic rate. 1 MET = 1 kcal/kg/hour at rest.
Calculation Formula
Intensity Factors
- • Low: 0.8-0.9x base MET
- • Moderate: 1.0x base MET
- • High: 1.1-1.2x base MET
- • Very High: 1.3-1.5x base MET
Personalization Factors
Age Adjustment
Metabolic rate decreases approximately 2% per decade after age 40. Our calculator applies age-based corrections for more accurate results.
Gender Differences
Men typically have 10-15% higher metabolic rates due to greater muscle mass. Gender-specific adjustments improve calculation accuracy.
Fitness Level Impact
- • Beginner: Standard MET values
- • Intermediate: +2-3% efficiency
- • Advanced: +5-8% efficiency
Frequently Asked Questions
How accurate are MET calculations?
MET values provide accurate estimates for the general population with a typical margin of error of ±15-20%. Individual variations exist due to factors like body composition, fitness level, and movement efficiency, but MET calculations remain the gold standard for activity-based calorie estimation.
How do I choose the correct intensity?
Low: You can converse easily during the activity. Moderate: You can talk but with some effort. High: It's difficult to maintain a conversation. Very High: Speaking is nearly impossible due to exertion.
What factors affect calorie burn?
Body weight is the primary factor, but age, gender, fitness level, activity intensity, environmental conditions (temperature, altitude), and individual metabolism all influence calorie expenditure. Our calculator accounts for the most significant variables.
Are food equivalents realistic?
Food equivalents are based on average caloric values and serve as motivational references to understand the effort needed to "burn off" certain foods. Actual calorie content varies by brand and preparation method, but these comparisons provide valuable perspective.
Can I use this for weight loss?
These calculations are excellent for monitoring physical activity and creating energy balance awareness. However, effective weight loss plans should also consider total daily energy expenditure, basal metabolic rate, diet quality, and ideally involve professional guidance.
What is a MET value?
MET (Metabolic Equivalent of Task) represents the intensity of an activity relative to rest. 1 MET equals your resting metabolic rate (approximately 1 kcal/kg/hour). Activities range from 1 MET (sleeping) to 15+ METs (high-intensity sports).
Is this calories burned calculator free to use?
Yes, our Calories Burned Calculator is completely free to use with no registration required, no subscription fees, and no limitations on calculations. All computations are performed locally in your browser for complete privacy.
