Unless my last 3 body fat measurements have been totally off I'm pretty sure that 13% of 230 is 29.9 pounds of fat. So that leaves just over 200 pounds lean mass. As for the 39 that is an honest relaxed measurement of my waist which is measured at your biggest area around the love handles and across the belly button. Guys with 50 inch guts still think they are 30 inch waists because their pants snug around there little asses. When measured properly people often find out how full of shit they are especially when measuring height. All of my fat stores have been right at my belly button area and on my sides. I look pretty cut right now even with my large waist. As for why I want to get to 5%, why the hell not. I know I can do it, with proper training and diet, plus for me I know that being skinny naturally will make it pretty easy. I don't know if you read my original post but it took me a long time and a lot of heavy eating to turn myself into 13% fat. 13% fat by most charts for males is still in the atheletic category. Most guys never see that after years of work, so naturally being thin for me is an advantage to getting even thinner.
