Does Masturbation Cause Weight Loss Burn some calories—typically around 3 to 5 calories per session—but it’s not enough to significantly contribute to weight loss. Weight loss generally comes from a sustained calorie deficit achieved through a combination of a balanced diet and regular exercise. Masturbation can have other benefits, like reducing stress and promoting relaxation, which may support a healthier lifestyle overall. However, if weight loss is your goal, focusing on diet and physical activity will be more effective.
