If I had to invent a new diet with a simple short list of dietary requirements, I would only have two: forbid binary thinking/lists and require mandatory prioritization.
Nothing wrong with a slice of birthday cake at grannie's 80th. Something hugely (lol) wrong with two packs of twinkies every lunch.
The "newer" it is, the worse it probably is to eat, and the older it is, the better it probably is to eat. Do your weekly/monthly meal planning based on that. I intentionally eat roughly 100 times as much apple by weight as chocolate. That doesn't mean I only eat apple or never eat chocolate. Most of my meals look something like a large salad, a large vegetable side dish, a relatively modest hunk of meat, and some citrus / fruit / berries for desert. I'm hardly starving or restraining myself. I'm actually something of a gourmet glutton. I just eat "old school" instead of modern stuff.
BTW in the olden days not every piece of fruit was supermarket scale picture perfect, as anyone who's hand picked their own strawberries probably knows? You're hungry, the somewhat fermented grapes still taste OK-ish... your liver evolved to clean up the poison... Ethanol is not supposed to be a primary source of calories, its a moderately toxic systemic poison which your body is fairly tolerant of, well at least compared to cyanides or organomercury compounds. Drinking it on a regular basis is about as stupid as eating arsenic or lead salts for kicks. Another good comparison is getting buzzed drunk is about as intelligent as sniffing carbon monoxide until dizzy. None the less as per the granny example above a glass of booze once in an occasional while is OK. Just as long as most of the time, lets say 10000 to 1 ratio, you drink water instead of chugging a beer. I actually like beer, I just don't drink 12 per night or even 1 per week. How often would you be comfortable drinking anti-freeze? I drink booze a little more often than that, but not much.
In a similar way there's nothing really wrong with an occasional pack of twinkies, as long as your lifetime average is running around 1000 carrots (or equiv) per twinkie.
I have noticed long term that tastes and physical reaction changes... I used to like jello, but now it kinda grosses me out. I mean I could eat some once in awhile, but I really don't want to anymore. Or ice cream, once you're not carb addicted anymore, lets be realistic, its sickly sweet combined with a mouth feel and texture like cold olive oil pouring down your throat, eww thats just gross, like sugar mixed with crisco shortening or "equal" artificial sweetener mixed with lard. Once in awhile I have some anyway and remind myself why I don't miss it anymore. This is before I start thinking about how it comes out of a cow and is designed to fatten up a calf, but I'm not a baby cow nor do I need any more fattening up.
