As she never leaves the house it should be quite easy for her husband to put her ion a strict diet. Oh I forget he is probably claiming benefits as her carer so if he got her weight reduced then these would stop.
Oh gawwwd. I know some people do have real food issues (oh go on, i'm being PC here), but seriously, bariatric surgery is a very big deal. The complications can be deadly. People have died from malabsorption of various essential nutrients. And all because you can't go for a walk and stop eating Greggs' sausage rolls? Drives me mad, because most people eat reasonably and exercise well and these others can't see it. They think it's luck and that food creeps into their mouths at night. And if i go into one more shop and can't find any size 8 clothes, i will wreck the place, i swear. Just because people can't be bothered to realise that we are not all fat.
