I didn't see him as having a 'hissy fit' when he was told the care contract was reducing. I saw him as being upset, and not sure how he was going to cope. Which to be fair is understandable.
I was also a bit taken aback at his sisters - there is surely more to the story than that. His mother lost her house (through her own agreement, effectively), so the sister aren't speaking to him because, as far as I can tell, they are greedy too - just for money instead of food.
His mother could equally have left the house to a dogs charity, it's not a right!
But that may be an easy reason for him to use for them not speaking - he has obviously been very selfish before he is in the state he is in, and I think there is probably much more to the reason why his family are having nothing to do with him than that.
I don't see people being cruel on this thread (as another posted suggested). I see honest reaction to the programme - and although I do have sympathy (thats no life) - it IS self-inflicted and it IS a disgusting state to be in. And to say otherwise is to pander to the morbidly obese and that does nobody, especially not the morbidly obese, any favours.
