I'm obese (bmi 31, i'm a big guy) but active: i walk several miles most days, lift weights, rock climb, and use the rowing machine, adding exercise on to my walks about 4 days a week. Still, it's easy to gain weight and hard to lose it.
There is some reason to think that environmental pollutants are impact hormones in humans causing an overall rise in obesity. Genetic factors definitely play a role. My father never exercised, ate what he wanted, and was always skinny. I was not so lucky.
