Yes, there is something wrong with a lot of us. Most people in industrialized nations have a disease that causes their insulin to not work so hot, called insulin resistance. Heard of it? So we can't eat a bunch of fruit without our energy systems going haywire and cusing us to feel hungry for more constantly because our muscles are starving. It's a bummer but at least we know.
When I was at 135 lbs, and I am 5'7" tall, my bf% was almost 25 %. At 125 lbs, my bf went down to 14%.
