User blog comment:Will od D./who can eat more J or L/@comment-2046973-20101019125440

Obiously Luffy, his body is made of rubber, so if he doesn't throw up, he can eat til' there is no food no more. Since Bonney's DF isn't explained so much, we don't know to what degree she can change age, but even if she made herself younger or older, I don't think she could eat more or digest it faster or something like that.
