Understanding Calorie Burn

How Calories Are Burned

Your body burns calories through three main processes: basal metabolic rate (BMR), thermic effect of food, and physical activity. Exercise increases your metabolic rate both during and after the workout.

BMR: 60-70% of daily calories burned at rest
Physical Activity: 15-30% through exercise and movement
Food Processing: 8-10% through digestion

MET Values Explained

MET (Metabolic Equivalent of Task) values represent the energy cost of activities. One MET equals the energy expended at rest, approximately 1 calorie per kilogram of body weight per hour.

Light Activities: 1.5-3 METs (walking, stretching)
Moderate Activities: 3-6 METs (cycling, dancing)
Vigorous Activities: 6+ METs (running, swimming)

Factors Affecting Calorie Burn

Several factors influence how many calories you burn during exercise. Understanding these can help you optimize your workouts for better results.

Body Weight: Heavier individuals burn more calories
Muscle Mass: More muscle increases metabolic rate
Exercise Intensity: Higher intensity burns more calories
Duration: Longer activities burn more total calories

Fitness & Calorie Burn Tips

Maximize Calorie Burn

Increase workout intensity, add resistance training, and incorporate high-intensity interval training (HIIT) to burn more calories in less time.

Monitor Heart Rate

Keep your heart rate in the target zone (50-85% of maximum) for optimal calorie burning and cardiovascular benefits during exercise.

Create Calorie Deficit

To lose weight, burn more calories than you consume. A deficit of 500 calories per day typically results in 1 pound of weight loss per week.

Combine Cardio & Strength

Mix cardiovascular exercises with strength training to maximize calorie burn during and after workouts through increased muscle mass.

Stay Consistent

Regular physical activity is more effective than sporadic intense workouts. Aim for at least 150 minutes of moderate activity per week.

Stay Hydrated

Proper hydration supports metabolism and helps maintain energy levels during workouts, leading to better calorie burn and performance.

Frequently Asked Questions

Our calculator uses scientifically-backed MET (Metabolic Equivalent of Task) values to provide accurate estimates. However, individual factors like fitness level, body composition, and metabolism can affect actual calorie burn by ±10-20%.

MET (Metabolic Equivalent of Task) represents the energy cost of physical activities. One MET equals the energy expended at rest. For example, running at 6 mph has a MET value of 9.8, meaning it burns 9.8 times more calories than resting.

This depends on your goals. For weight maintenance, balance calories consumed with calories burned. For weight loss, create a deficit of 500-1000 calories per day through diet and exercise to lose 1-2 pounds per week safely.

Yes, muscle tissue burns more calories than fat tissue, even at rest. People with higher muscle mass have higher metabolic rates and burn more calories during both exercise and daily activities.

Several factors influence calorie burn: body weight (heavier people burn more), exercise intensity and duration, muscle mass, age, gender, and environmental conditions like temperature and altitude.

To maximize calorie burn: increase workout intensity, incorporate high-intensity interval training (HIIT), add resistance training to build muscle, stay consistent with your routine, and combine different types of exercises.
