Activity Intensity Levels (MET Values)

Intensity Level MET Range Example Activities
Light 1.5 - 3.0 Walking slowly, light housework, stretching
Moderate 3.0 - 6.0 Brisk walking, cycling (light effort), dancing
Vigorous 6.0 - 9.0 Jogging, swimming laps, aerobics
Very Vigorous 9.0+ Running, HIIT, jump rope, competitive sports

MET (Metabolic Equivalent of Task) is a measure of the energy cost of physical activities as a multiple of resting metabolic rate.

About Calorie Burning

Calorie burning refers to the energy expenditure that occurs during physical activity. Understanding how many calories you burn during different activities can help with weight management and fitness goals.

How Calories Burned is Calculated

The calculation uses the MET value of an activity, your weight, and the duration of the activity.

Calories Burned = MET × Weight(kg) × Duration(hours)

Where:

  • MET (Metabolic Equivalent of Task) is the energy cost of the activity
  • Weight is your body weight in kilograms
  • Duration is how long you performed the activity in hours

Factors Affecting Calorie Burn

Several factors can influence how many calories you burn during physical activity:

  • Body weight: Heavier individuals burn more calories performing the same activity
  • Intensity level: Higher intensity activities burn more calories per minute
  • Fitness level: As you become more fit, your body becomes more efficient
  • Age: Metabolic rate tends to decrease with age
  • Body composition: Muscle burns more calories than fat, even at rest
  • Environmental factors: Temperature, humidity, and altitude can affect calorie burn

Using Calorie Information Effectively

Here are some tips for using calorie burn information effectively:

  • Remember that calorie calculators provide estimates, not exact measurements
  • Focus on consistency rather than occasional high-intensity workouts
  • Combine increased physical activity with proper nutrition for best results
  • For weight loss, aim for a moderate calorie deficit (500-750 calories per day)
  • Track your progress over time rather than focusing on daily fluctuations

Always consult with healthcare professionals before starting a new exercise program, especially if you have pre-existing health conditions.

Frequently Asked Questions

How accurate is the calorie burn calculator?
The calorie burn calculator provides an estimate based on average MET values for different activities. Individual factors like fitness level, efficiency of movement, and environmental conditions can affect actual calorie burn. For more precise measurements, consider using a heart rate monitor or fitness tracker that accounts for your personal metrics.
How many calories should I burn to lose weight?
To lose one pound of weight, you need to create a deficit of approximately 3,500 calories. A safe and sustainable approach is to aim for a deficit of 500-750 calories per day through a combination of reduced calorie intake and increased physical activity. This would result in a weight loss of about 1-1.5 pounds per week. Remember that weight loss should be gradual and sustainable for long-term success.
Why do I burn fewer calories doing the same activity over time?
As your body becomes more efficient at performing an activity, it requires less energy to do the same work. This is a normal adaptation to exercise. To continue challenging your body and burning calories at a similar rate, you can increase the intensity, duration, or frequency of your workouts, or incorporate variety by trying different types of activities.
Is it better to do longer, low-intensity workouts or shorter, high-intensity workouts?
Both approaches have benefits. Longer, low-intensity workouts (like walking) are generally easier to sustain, gentler on joints, and good for building endurance. Shorter, high-intensity workouts (like HIIT) can burn more calories in less time and may continue to burn calories after the workout through the "afterburn effect." The best approach is to incorporate both types into your fitness routine based on your goals, preferences, and physical condition.
