Hello doctor! I am doing workout from last 6 months. And now I am just cutting down my fat from my body, so my gym trainer told me to go on a zero carbohydrate diet. I started this diet from yesterday. In all day I only eat egg whites and whey protein. So I am just facing one problem after that diet is my erection level is decreased. I don't have any erectile dysfunction ever before. Even the day before yesterday my erection was good enough. Then I asked this to my trainer that why is this happening then he said that everything will be fine. I'm confused now that if if I don't eat carbohydrate for a month then what will be gonna happen?
