Hi I choose not to have carbs on my pre op as otherwise I would have craved them, and once you stop, after a few days the craving does go! I had prawn salads, scrambled egg (difficult with only 1 egg!) with nice cherry tomatoes, chicken and veg, fish and nice veg etc.. I wasnt hungry at all after a few days on the diet. I did cheat and add gravy (as I wasnt having any carbs I thought 2 tablespoons would be OK) so I could have chicken dinners, without the mash and this was lovely. You can do this!
