For me, nothing is off limits or forbidden. To me...that is giving food WAY too much power.
That said, I've had to be really mindful about eating some things. Really sugary, refined flour stuff...like birthday cake or a fancy desert....if I want to eat it, I've gotta do the work to figure out what a 200 calorie serving is. If I eat much more than 200 calories of sugary refined stuff it's no longer a treat...it's super unpleasant. I don't puke or anything, I just feel kinda gross and unwell for half an hour. But hey....a little teenie piece of cake, a midget scoop of ice cream, a piece of a favorite donut, a small serving of a "mom desert"....is workable and enjoyable when it's a rare treat and the amount is reasonable. (rich stuff might only be a couple of bites)
Rather than having forbidden foods...I have foods that I need a 24 hour waiting period on. LOL. Some foods, I refuse to eat on impulse or short notice anymore. But if I have time to plan for them in my whole day's nutrition and can plan out a reasonable portion....nothing is ever off limits.
I'll also run cycles of four weeks with zero junk food, then one week with limited junk as desired. That way....if I want something bad enough to wait a couple of weeks for it...I can have anything I want.
Off limits = food wins. I want to win. I want to control food, not have food control me.
Stuff I have to be careful of: My beloved corn on the cob. Too much corn no the cob can still cause my banana stomach to feel stuck. I still eat it...cause I love it....but I make sure to eat bites of other things between small bites of corn to keep it from packing up.
I do find that I like a lot of my old favorites less. Sugary stuff is wonderful for about the first three bites....then I'm done. Have learned through experience to enjoy a few bites and not push my luck.
Several old favorites don't taste the same to me or satisfy the same way. Sometimes it's liberating to try old favorites and find out the appeal isn't there anymore. Lot of things are off my naughty list purely because they don't taste as good as my memory of them.
