the first few months can be a challenge (although fortunately, most of us lose our sense of hunger for the first few months, which makes it easier), but after that, not really. At least not food-wise. By six months out I was cleared to eat anything my stomach could tolerate, which for me is pretty much everything. I eat a lot less than I used to (obviously), but no one would guess I had bariatric surgery at this point. They'd probably assume I'm just a light eater, like lots of my women friends who've never been obese. When I go out, I'll sometimes order just an appetizer or a salad, or if I get an entree, I'll eat half of it and take the rest home to have for lunch the following day. A lot of my friends do the same. I worried about this too since I'm a food lover as well, but other than cutting my portion size and just enjoying things like desserts occasionally, I really don't notice a huge difference. I do try to prioritize protein and vegetables since I need the nutrients (we all do) and my stomach is small, but I don't deny myself anything. Although there are some things like rice and pasta that tend to sit in my stomach like a brick. I still eat those occasionally, but not a lot of them at one sitting.
P.S. your comment about being afraid you won't enjoy food. I enjoy it a lot - too much! (I've been in maintenance for years and it can be a struggle to keep from gaining weight). For the first few months after surgery, though, most of us lose our sense of hunger for up to a year (my hunger came back at five months out). Many of us also do lose some interest in food, too (and that comes back too!). But even though it's weird at first, enjoy it while it lasts and take full advantage of it. To be honest, I found it very liberating. It was so easy to lose weight when I was never hungry and didn't give a flip about food for the first time in my life! once I got over the weirdness of it, I LOVED it and wished I was one of the very lucky few whose hunger never came back (but again, it does come back for the vast majority of us)
