Lose Weight Masturbating itself is a natural and normal part of human sexuality, but when it comes to weight loss, it’s important to clarify that masturbating alone will not significantly contribute to weight loss. While it does burn some calories, the amount is relatively small compared to the calories burned through regular physical exercise like walking, running, or strength training. To lose weight, you need to create a caloric deficit, which means burning more calories than you consume. Exercise, including cardiovascular activity and strength training, is much more effective for creating a substantial calorie deficit.
