Good rule of thumb though she looks like she needs to be eat more of everything could be photoshoped though or maybe she's just built like that who am i to judge but that doesn't look healthy to me either
Bob Harper: The Skinny Rules. I've read this and even if you pick up 1 or 2 rules from this book you will loose weight and feel better about yourself!! Of course it's better to follow all the rules but if your having trouble start slow with 1 or 2 and just keep adding a rule every week!!! It works!!!
