Yes, Does Mastrbation Cause Weight Loss, but the amount is relatively small compared to more intense physical activities. During masturbation, the body engages in a brief period of physical exertion, which results in some calorie expenditure. However, it is not a significant contributor to weight loss. The reason masturbation doesn't burn a lot of calories is that the intensity and duration are relatively short. Most people engage in masturbation for just a few minutes, and while there is some muscular activity and an increase in heart rate, it is not sustained or intense enough to significantly impact calorie expenditure. Masturbation does burn a small number of calories, but it is not a practical method for weight loss. If you're looking to burn more calories or lose weight, regular exercise, such as cardio workouts, strength training, or even walking, is much more effective.
