It's not real hunger, it's "head hunger." The very fact that you are indulging things that you SHOULD NOT BE INDULGING tells me that your head isn't in the right place, right now. It's normal to be a little obsessive about food the first couple weeks after surgery, your brain has a hard time letting go of its old behaviors. But instead of embracing that change and letting go, you're letting your brain dominate you again. If you continue to do that, you are not going to be successful long-term. The internet is littered with stories of people who did this and regained all of their weight, because they were not committed to change, ignored their surgeon's instructions, did what they wanted and gained it all right back. Sure, the surgery will force you to lose for a while...but it won't stop you from regaining it, if you're motivated.
11 pounds in a week and a half is excellent weight loss, so when you say you think it should be more, it tells me you don't really know how much of a calorie deficit you're running, how many calories your body needs to stay its current weight, and how many pounds you SHOULD be losing, given your calorie deficit. These are all important things to know, and these are knowledge and skills you will need to acquire if you are to be a success.
Right now, you need to commit to following your dietitian and surgeon's instructions with 100% compliance. Not 99%, not mostly kinda sorta, 100% without fail. You also need to commit to a lifelong change in your habits and thought patterns related to food. If you keep letting it dominate you, you will fail at this.
The rumbling in your stomach that you're feeling is not hunger, it is something that goes away after enough time post-surgery...your stomach just had the majority of itself cut away, it is a recovering muscle and it is spasming, doing all kinds of stuff that has nothing to do with hunger. It'll do all of that AFTER you eat, too. You also likely feel a "bite" in your stomach which reminds you of hunger pangs, but in reality is stomach acid buildup because your stomach hasn't adjusted to its new size yet, along with some residual soreness from the full-length staple line. Again, this is something that will resolve in time. It is YOUR HEAD that is driving your feeling that you're hungry...and your behavior is allowing your old mindset to control you, yet again. "I'll just have some of these wings, they're small, I'm so HUNGRY." No, sorry...you're screwing up already...less than two weeks after surgery.
Water, and Protein, in whatever form your dietitian and surgeon have advised. You are probably still supposed to be a liquids only. Next would be puree, most likely. STICK TO YOUR DIET. You went to all the trouble and expense to get operated on, why wouldn't you put the work in to fix the thing they can't operate on - your brain? That is at least 90% of what needs to be fixed, for you to succeed. The surgery was just a tool.
Sorry if this comes off as harsh, but I hate it when I see people asking questions about whether they're stretching their stomach or if they should be able to eat so much, when they aren't following the rules that have been laid out for them, at all.
