I think anybody can get to those bodyfat levels. It may be harder for some than others. Maybe i shouldn't have said it was all about diet because there are other factors. Raising your metabolism is dependant on several things. Meal spacing, breakdown of carbs to protein to fat that you eat, amount of muscle you have, amount of cardio, etc are all factors. The hardest part is getting where you want to be. It is not nearly as hard to maintain. People who don't workout usually get out of shape and then have a hard road ahead instead of just staying in decent shape with a little work.
