Apparently the best way to increase the size of your penis is to force all the blood to the end when it's semi-erect. However, I suppose that's only stretching it, it probably won't do anything for your sexual performance and it's girth that makes more of a difference than length.
High protein diets can promote weight loss, just look at the Atkins diet for example, almost all meat and no vegetables and see the weight, come off.
