Fat people seem to think so; although I think that in 99% of the cases, this is an excuse -- a rationalization -- for the lack of discipline to lose weight.
I weight about 30 pounds more than any chart I can find. My blood work is perfect. I can keep up with probably 80% of men my age (55+) on the track or road.
I never smoked and don’t drink.
So, on paper I am as fit as you can get for a fat guy.
My guess is that my frame is going to fall apart before most men my age because of the stress on joints and what not.
If anyone things walking is lame exercise consider this: I started a new job after taking a few years off to care for some relatives. I walked every day for about an hour.
Now...I put on 15 of those 30 pounds since the end of May. Sitting on my ass is killing me. We haven’t changed our diet, which is mostly protien and few carbs.
So, yes, for a short term you can be fit and fat. But not for ever.
