Thank you all for your input. I appreciate you taking the time to locate and type out the information for me.
Megan, that link was very interesting. Thank you for looking it up and posting it here. The instructions are very different from the ones I was given. There was nothing in my instructions about the day prior, other than fat restrictions on the "evening meal". I hope I haven't missed part of the instructions because I've been eating normally so far today, and (fat free) milk is one of the things I do plan to consume with my supper.
Bruce, what you wrote makes sense, it goes along with what I thought. After checking online for ideas I assumed they must really mean very low fat/no extra fat, even though the written instructions from the gastroenterologist say "No fat".
gnomad and Backwoodsman, when the hospital phoned me with the time I'm to be there I asked if I could eat "low fat" and was told, "No fat" means "No fat".
I was given a standard handout and wonder if the fat restriction is appropriate in my case? They ruled out the other liver problems in a previous CT scan. This is a six month followup for the small tumor they found then. Hopefully what I eat will work out okay for the scan. I wasn't given these instructions for other scans.
I'm sure I can survive without a "normal" supper tonight. It looks as if it will be no fat milk and angel food cake with blueberry spread. My diabetic snack before bed will be a repeat of supper.
Thanks again, everyone.
