As far as carbs, my bariatrician gave me a number before surgery, while I was doing the insurance diet, of no more than 100 carbs a day, but obviously preferrably as low as you can get. With the small portions and high Protein intake I've had it's nearly impossible to get anywhere near that regularly. I don't think I've gone much over 70 at all since at least 2 weeks before surgery.
The rule I have at this point since I've made it to "healthy diet" stages is three "meals" a day obviously starting with protein first and two high protein Snacks a day and obviously lots of Water.
I haven't had sweets since my surgery other than sugar free Jello one day after surgery that was too sweet. I have some frozen greek yogurt for a high protein snack that I haven't eaten yet and sugar free popscicles. Mostly I've been going to the store and while I'm there I'll pick up packages of things I used to like and basically if the sodium is super high &/or if there is less than 4g of protein per serving I put it right back down. Helps eliminate the junk food obviously. Plus there are a lot of fun substitutes.
For example, I bout a bunch of seeds and nuts to snack on for preotein and fairly low carbs. All I do is find a seasoning I really like (I buy that Mr. Kernel popcorn seasoning since for being a seasoning its still not a ton of salt) spritz the seeds/nuts with olive oil Pam and sprinkle a little seasoning and shake it up. Flavored like chips but high in protein. I also buy flavored pork rinds, to get a sensation like chips with no carbs, low fat and pure protein.
I am happy to say that since yesterday my weight creeped down a tiny bit so maybe I'm finally over that hurdle. We'll see!
