I find it difficult to understand how being slim can change your life so dramatically i know my life is extremely restricted because of my weight but i also need food not in a basic way and can't get my head around how being without the quantity of food i want can be outweighed by being slim. This is not a critiscism of you I think it is absolutely amazing what you have done and it is what i want but can i give up food for it that is my current dilemma.
I think it's great you're exploring this first so you can make an informed choice about your op.
One of the things that's so massively life changing is that quantity you're worried about, that insatiable pre-op appetite, becomes a thing of the past. You get that full sated feeling very quickly and from the much smaller amounts.
I was lucky as in I didn't really feel my life was that limited by the weight. I had no health issues. Only now that I've lost the weight do I really get how badly it was holding me back and how life changing it is just to do the simple things that most people take for granted.
Sitting on a chair without worrying it will break, seat belts fit, going on rides, not getting stared at out and about, going ice skating, not being out of breath from going up a flight of stairs, shopping off the peg in normal sizes.
If you're worried about limitations of types of food from the bypass have you considered the sleeve?
There was a period of mourning for food from me. Sometimes I got sad at not being able to eat more of the food prepared but that's a short phase. Once you get further out you do get less restriction. I also can eat/drink almost everything I did pre-op, just in smaller portions. I'm 14mths out and that's my norm now.
I love how for the first time in my life my body knows when to stop and responds to hunger signals and cues like people of normal size. I have no regrets.
