If you're at a healthy BMI AND exercising regularly then you get to be a minority within the already small minority of normal sized people. I'd really love to know what percentage of people in the US hit both points. Because there's sure as hell not a lot of people who aren't in the overweight or obese range. Take away people who calorie count to lazy skinny and the skinnyfats and I can't imagine there'd be very many people left.
