Interesting question!
I don't have a ton of routine when it comes to meals, with the possible exception of breakfast. Most days I eat a yogurt parfait with Greek yogurt, fresh berries & protein boosted Kind brand granola. That said, I'm not opposed to other things like banana nut pancakes (a favorite), or even cold pizza on occasion!
Lunch is most often leftovers from dinner since we still haven't figured out how to cook 1.5 meals (half for me, whole for my wife). Dinner is super varied. We both like to cook and like good food, so it might be just about anything. That said, I have found that I just don't enjoy big slabs of meat anymore. We do occasionally have red meat, but it's probably once a week or less. I'd say we have seafood based dinners 3-4 times a week and 1-2 vegetarian meals per week. I also eat a lot more beans than I used to.
Overall, I don't focus much on macros. It's more about eating a variety of healthy foods and enjoying what little I can eat.
As far as activity, there is no typical day. It can vary from nothing at all (I do one dedicated rest day a week), to running 12-14 miles or more on my long run day. In a typical week, I run 30-40 miles (my main sport), but I also do strength training a couple days a week and do a little bit of cross training either on the bike or on a stationary rower. Later in the year I'm thinking of starting a marathon training block. If so, I'll be increasing my mileage up into the 50-60 MPW range.
I think one of the main reasons my diet may differ from the "typical" post WLS diet is because of the high activity level I have. I just wouldn't be physically able to do that volume of running without eating a lot more carbs to fuel my runs. In fact, getting enough calories is my current challenge, not getting too many. That's another topic for another day however!
