Never try to help fatties... I'm quite good in nutrition topics, especially in calculating nutritionally complete days even when you have to (want to) avoid (many) foods.  So, a friend of mine ballooned recently, went from "on the edge" (chubby but normal weight) straight to obese. She also went from quite pleasant to fucking annoying and whiny.  So, after crying about severe digestion problems for months now and not being able to tolerate food, her doctor set her on a pretty strict diet. Don't ask me how you can balloon when actually feeling sick all the time, vomiting & having diarrhea, she kind of managed it.   For those who don't know it, those diets really are extremly limiting but you only do them for a couple of weeks, then slowly start reintroducing other foods and keep a diary about how your body reacts to them.  She knew that I had to do the same thing years ago, so she asked me for help. I offered her all the help I could and guess what? There is an excuse for everything. Literally everything. Long story short: Fatties prefer feeling like absolute shit over going on a diet for a few weeks. Like she was REEEEing about her health issues for months, complaint non stop about not getting help from doctors. Doctor offers help "go on a diet". But no, that's too much. They prefer being sick.  Best argument "I would get deficient in nutrients because this is so limiting". a) Have you ever cared about nutrients before?  b) You are still allowed to eat quite some foods, that would be absolutely nutritionally complete if combined in the right (maybe not so tasty) way.   c) Take a multivitamin.  d) You don't get severe deficiencies from being on a restricted diet for a few (!!!) weeks. But yeah, her other fat friend told her it would be dangerous to eat such a limited diet.  And silly me wasted her time. Yes, should have known that before. Yes, I shouldn't have put in the effort.
