I think there is a healthy, reasonable medium between eating hostess cupcakes as a meal (no judgment from me on that one man, been there done that!) and never even looking at a carb again LOL. I think everyone in this thread is right that you would do well to see your dietician and your psych, too. you don't have to go this alone. this is for life and you need to find something you can live with, and pinballing between extremes won't serve you in the long run. I'm all for having some dark chocolate after dinner or sweet crepes for Breakfast once a month, but it sounds like the concept of moderation is giving you a hard time here. that's okay. it's not a moral failing, it just... is. you've gone through a major life change and you're trying to find your new equilibrium. you know you have a history of abusing alcohol, and it sounds like after depriving yourself, some part of you wants to move on to abusing food instead. even if you don't gain back all the weight you've lost, it doesn't mean that's healthy for you physically or mentally.
real talk? you may have lost some weight after overdoing it on the empty carbs... so far. but that doesn't mean empty carbs are the key to weight loss or health. don't take this as a sign that you have miraculously become one of those people who eats junk all day and still gets to maintain a normal BMI. the surgery does a lot of things, but I don't think it's quite THAT powerful LOL. although I imagine a lot of us wish it was. and even then... the scale is not the only measure of health. plenty of people with normal BMIs can be unhealthy if they're not adequately nourishing themselves.
you know being extreme low carb doesn't work for you. that's fine, it doesn't work for a LOT of people. this is where some sensible guidance from a professional dietician becomes of use, because they can help you re-introduce carbs into your diet in a reasonable way that satisfies and nourishes you, but doesn't go overboard in the complete opposite direction. you know?
