Who considered you obese? Also is it healthy to even have <5% body fat?
My body-fat percentage is definitely not 5%, though. My guess is that it's around 14-15%. Everyone drastically underestimates how low their body-fat percentage is, and I am not a bodybuilder. I lift heavy and like pasta.

I'm not sure of the health factors but if you're training for 2 - 2.5 hours a day and dieting it can be normalish.
Why the down votes?
