i'm classified as obese as well, and truly, it's nobody's business, as long as the individual is happy as they are. thing is, most of the people banging the "big is beautiful" gong that i've interacted with, i've found have decided that accepting being unhealthily fat is easier than doing something about it.
as for the "don't have time to worry" about being healthy? you either take the time now, or you likely die years (or even decades) early. just because you can't afford healthy food doesn't mean you can't slim down a bit. eat less of the junk, move more, etc. going to mcdonald's? just get a small hamburger, small fry... you know? there are so many little steps.
well, not my place to say either way, just trying to express my opinions. i'll shut up now...
