Based on your description of your relative I would tell her to talk to her doctor. Certainly give her all the info on the diet so she can intelligently inform her doctor about it, but she needs to be straight forward with her doctor. Her health is too important. My doctor was quite happy to have me try it...she was just worried i couldn't stay on it..she said most people don't ....I told her that is true of any "diet"...but this is my new WOL!!

Anyway,hopefully her doctor will be open about it, but even if she cuts back some on her carbs, that is a start and as you say if she is already eating high fat and high carbs if she does that, then she will be LC'ing! As long as she doesn't go low fat, she won't be hungry.

Good Luck....
