About Sexual Activity and Calorie Burn
Sexual activity provides light to moderate physical exercise depending on duration and intensity. Research from the University of Montreal found that the average sexual encounter lasts about 25 minutes and burns approximately 85 calories for men and 69 calories for women. Heart rate during sexual activity typically reaches 70-80% of maximum, comparable to moderate-intensity exercise. While not a replacement for structured exercise, sexual activity contributes to overall physical activity levels and provides additional benefits including stress reduction, improved sleep, and cardiovascular health.
Understanding the MET Value
Sexual Activity has a MET (Metabolic Equivalent of Task) value of 1.8. This means sexual activity burns 1.8 times more energy than sitting at rest. The formula used is: calories = MET x 3.5 x body weight in kg / 200 x minutes. For example, a 70 kg person doing sexual activity for 1 hour would burn approximately 132 calories. MET values are sourced from the Compendium of Physical Activities and should be treated as useful estimates, not exact lab measurements.
Tips to Maximize Your Sexual Activity Calorie Burn
- Focus on overall fitness to improve endurance and enjoyment
- The more active your role, the more calories you burn
- Longer duration naturally increases total calorie expenditure
- Core strength and flexibility enhance both performance and calorie burn
- Combine with an overall healthy lifestyle for maximum health benefits

How We Calculate Calories Burned During Sexual Activity
Our sexual activity calorie calculator uses the standard MET oxygen-cost equation, a common method used in exercise science and public-health research. For this calculation we use sexual activity at MET 1.8. The formula is:
Calories = MET x 3.5 x Weight (kg) / 200 x Minutes
For sexual activity with a MET value of 1.8, the calculation works as follows: If you weigh 160 lbs (72.6 kg) and do sexual activity for 30 minutes (0.5 hours), you would burn approximately 69 calories.
Keep in mind that actual calorie expenditure can vary by 15-20% based on factors like fitness level, exercise intensity, environmental conditions, and individual metabolic differences. The selected MET value of 1.8 for sexual activity represents an average across typical conditions and effort levels. Your actual burn may be higher or lower depending on how vigorously you perform the activity.

View All ActivitiesMethodology & Calorie Burn Data Sources
How we calculate sexual activity calorie burn: The MET (Metabolic Equivalent of Task) value of 1.8 for sexual activity comes from the Compendium of Physical Activities (Ainsworth et al.), a standardized reference used in exercise and public-health research. Calorie expenditure follows the formula: kcal/min = (MET x 3.5 x weight in kg) / 200, then multiplied by duration.
- MET value for sexual activity: 1.8 (low MET = light, 3-6 = moderate, >6 = vigorous per ACSM classification).
- Body weight scaling: heavier individuals burn more calories per minute at the same activity. Our calculator adjusts based on your input weight.
- Duration scaling: linear with time at constant intensity. Real workouts may include warm-up, cool-down, and rest periods affecting average MET.
- Individual variation: actual burn varies ±10-20% based on fitness level, body composition, exercise efficiency, and metabolic rate.
- EPOC (afterburn effect): high-intensity activities may burn additional calories post-workout, but that extra burn varies widely and is not included in baseline figures.

Health Disclaimer: Calorie burn estimates are general guidance, not precise measurements. Wearable devices (Apple Watch, Fitbit, Garmin) using heart rate provide more personalized estimates. Always consult a physician before starting an exercise program, especially if you have heart conditions, diabetes, or are pregnant. Never use exercise to "earn" food in a way that disrupts a healthy relationship with eating.

Frequently Asked Questions
How many calories does sexual activity burn in 30 minutes?
A person weighing 160 lbs (73 kg) burns approximately 69 calories during 30 minutes of sexual activity. This is based on a MET value of 1.8 for sexual activity. Heavier individuals burn more calories, and lighter individuals burn fewer.
What is the MET value of sexual activity?
The default MET (Metabolic Equivalent of Task) value for sexual activity is 1.8, while the selected training style uses MET 1.8. This means sexual activity burns 1.8 times more energy than sitting at rest. MET values are established by the Compendium of Physical Activities and represent average energy expenditure for the activity.
Is sexual activity good for weight loss?
Sexual Activity has a selected MET value of 1.8, which means it burns a moderate amount of calories. A 160-lb person burns about 137 calories per hour. While not the highest calorie-burning activity, consistency is key for weight loss. Regular sexual activity combined with a calorie-controlled diet can contribute to gradual, healthy weight loss.
How does body weight affect calories burned during sexual activity?
Body weight significantly impacts calorie burn during sexual activity. At the selected MET value of 1.8, a 120-lb person burns about 51 calories in 30 minutes, while a 250-lb person burns approximately 107 calories in the same time. This is because moving a heavier body requires more energy, regardless of the activity being performed.
What muscles does sexual activity work?
Sexual Activity primarily works the Core, Glutes, Quadriceps, and Hip Flexors. Regular practice helps strengthen these muscle groups and improve overall fitness.
Is sex enough exercise for weight loss?
Sex can contribute to daily activity, but it is usually not enough by itself for a weight-loss plan. Treat it as light-to-moderate movement and rely on consistent nutrition, walking, cardio, and strength training for the main calorie deficit.
How many calories does sexual activity burn per hour?
At the selected MET value of 1.8, a 160-lb person burns about 137 calories per hour during sexual activity. A 120-lb person burns about 103 calories per hour, while a 200-lb person burns about 171 calories per hour.
