I just don't understand how you can get disability for being too fat to work.
Agreed, though I do have sympathy for those with Genetic conditions that cause obesity, but if it can be solved by diet, it was probably caused by diet. I know sometimes psychological conditions can cause weight gain, but I don't really consider that Disability so much as long-term illness, which, in the UK, means sickness benefit for 6 months and then normal Income Support.
Anyway, any woman who is willing to treat herself as a Freak Show for magazines like this (she cannot be unaware of the general publics' response to stories like this) suggest that this is not a case of self-image problems.
