Hello, I'm not sure if you can help me with this but I have a friend whom is Vegan but only lives with a healthy diet. As in she will not permit herself to have any foods that are processed or dessert related foods like chocolate or anything sweet. She also seems to be working out a little too much and all this in the goal of losing weight. I've tried telling her she might be suffering from an eating disorder and that her health only diet might not be as healthy as she thinks it is. I do assume that restricting yourself everyday from having certain foods because they contain sugar might be somewhat awful on the mental side of her health. I would like to know, aside from a constant deficiency in B12 and iron what else would be unhealthy in being an overly healthy Vegan that works out every day of the week.
