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.
