Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Masturbation and losing weight has no connection. Its false belief. In fact people have many false belief as for masturbation. Masturbation never harms anybody, nor it causes loss of weight. Masturbation has some advantage. It will satisfy your desire, clear the mind and makes person more efficient to work. In my advice you should not think of withdrawing the masturbation. Instead you can think for the gaining weight by exercise and good diet. Regular daily exercise and high protein diet can help in gaining weight. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
