Oops, my mistake. I got confused by this table on the WebMD page below which does list 18-25% as an acceptable range for body fat percentage:

http://www.webmd.com/diet/features/body-fat-measurement#2

So my original numbers were actually correct, but instead of the CDC it's the American Council on Exercise, whatever that is. The page before has the CDC recommendations on BMI. I was surprised too that 25% is considered acceptable. I am aware of the difference between BMI and body fat percentage, and that the former is an inaccurate gauge of fitness.

Considering the American Council on Exercise pushes the "Health at Every Size(C)" bullshit I'd never take them seriously. I can't be bothered to go find real studies on the issue but I would have to guess they'd tell you there's an increased risk of health issues at 25% body fat.

Ah ok, I suppose I expected WebMD to rely on better sources of information. I stay around 7-10% body fat and feel good in that range -- the few times I've gone below that I felt lethargic and performed poorly in sports.

WebMD is the buzzfeed of medical knowledge.

I suspect you're not actually at 7-10% body fat, that is ridiculously low. Like just skin and muscle, nothing else. It is physically impossible for most people to go below 7% without some serious drug abuse or eating disorder. Google image search "7% body fat" and see for yourself.
