Irrelevant. They have a choice as to whether or not to consume a non-fattening number of calories regardless of the disease they have. There is a floor to the number of calories one consumes such that you will not put on fat no matter what disease you have, and that metabolic floor is not even obscenely low (though it does limit what you can eat). I know people who ride the edge of that floor voluntarily (I think they are crazy, but it is their life).
Ever seen a body ravaged by chemo, or reliant on prednisone?
Yes and yes. Neither causes fat to materialize on the body, the subject at hand.
Do you know what it is like to see a four year old child bloated from disease and an attempt to keep her alive: while getting the bare caloric necessities through a damn feeding tube?
Again, what does this have to do with getting fat? Being bloated has nothing to do with being fat; stop trying to conflate unrelated subjects in your rant, you've said nothing relevant to fat management.
Weight is NOT always a matter of self-discipline. Often, yes. Always, no.
Weight, no. Fat, yes. It is disingenuous to conflate the two when we are talking about the latter and not the former.
You are a jerk.
Probably, but saying so does not help you demonstrate that people get fat by magic or some other means other than poor caloric discipline. The subject of discussion here, and my previous post, was the consumption of calories in excess of metabolic need. Every obese person does this, and does it unnecessarily regardless of any disease they may have.
Ok, now that I've said my piece, I need to ask your forgiveness for calling you a jerk. I hope you will forgive me for that. Having my buttons pushed is no excuse and I should have had more "self-control."
