Lack of ability to meet dietary requirements (and beyond that, total apathy, disinterest and ignorance as well) has long been an issue.
I get berated by consultants about my diet, about my inability to manage my diabetes to the degree they want it managed, about the pain my inoperable gallstones often cause, about my weight... its EASY, just have more will power, just work harder at it.. they say.
Then, when I am hospitalised, the foods they offer are the exact foods I am told to avoid, and oh, its not easy, its actually FAR too difficult for them to provide a gallstone friendly, diabetic friendly, vegetarian diet.
I am indeed outrageous for suggesting they should be able to do so.
I did lose a stone in nearly a fortnight... that triggered my gallbladder to flare up again, as sudden starvation and weightloss will do.
YANBU OP. Not at all.
