Welcome, Beth. If you have specific questions, use the search icon up in the right corner.
Many members have listed their food consumption, so you might search all the archived posts by keyword, like "eat" or "sugar" or "protein," just to name a few. There are also exact diets listed below, in our resource section. But you should understand that what works for one person won't work for another. You must have been given a list of post-op suggestions after surgery. If you can't locate it, you can search through the posts using any particular food that appeals to you or makes you feel sick.
This isn't a diet group per se, but a support group, so jump on in and tell us more about what you're going through.
And everyone has trouble with post-op gain. There's almost always a reason for it, like being sedentary or sneaking treats. I'd advise you to start a food journal right now, and list every CRUMB of food that goes into your mouth. Also, get a food scale so you can measure food by weight, and accurate measuring cups and spoons, and use them every time.
One of the best old adages people have trouble with is chewing each bite of food at least 30 times. And put your fork and spoon down between bites. I don't recommend Weight Watchers except for the fact that they've been really good about helping people identify portion sizes. Like, 3 ounces of chicken is about the same size as a deck of cards.
People also use sugar substitutes is fine, but I prefer eating foods without needing a sweetener. Things like apples and even a plain piece of toast can be very satisfying.
Good luck and again, welcome.
