Does Masturbating Cause Weight Loss burns some calories, but the amount is relatively small—about 3 to 5 calories per session? While it can contribute to overall physical activity, it's not significant enough to lead to noticeable weight loss on its own. Weight loss is most effectively achieved through a combination of a balanced diet and regular exercise. Focusing on aerobic activities, strength training, and healthy eating habits will have a much greater impact on weight management than relying on masturbation.
