"Can fat people help being fat (I mean obese, hugely fat)?"

I don't know..I think there are some people that have medical issues that contribute to obesity...
Probably though it's just that it's more difficult for some people due to a number of factors..i.e metabolism, diet, ability to exercise..
One of the worst things you can do is eat sugary foods and then sit down for hours at a time...truckers, office workers, etc..
For me personally, in order to be fit I have to walk at least 5 miles a day and eat only raw veggies and maybe a tiny bit of chicken...which I'm able to do now but when I was working 12-14 hours a day it was not possible..I didn't have enough time to walk or prepare healthy foods..
I think there are many people that are in similar situations..and also there are many people that just don't understand that Food Matters
And of course there are people that are just fat and lazy and don't give a fuck because they'd rather watch teevee and play vidya games instead of doing any kind of physical activity..also maybe they don't care about their appearance because you don't have to look good to watch pr0n and beat off?
