I know a few MA that are in great shape other than looks wise.
Some guys are just "husky" and don't really care about being ripped.
Depending on which cycle in my training I am doing I can be husky or ripped, simply because of the type of training I am doing.
I know a few Goju guys that are in great shape but have guts because they like to eat and like beer, but in terms of strength and cardio, they are excellent.

None of that takes away that being a fatass is NOT the way to go.
