Whole food vegan for a week, ate one processed cookie and hated it

Guilt is a powerful emotion and taste is subjective.

Some calorie dense foods are really just not that tasty, they just push evolution-installed buttons that have been strengthened by advertising and habit (fat! sugar! easy!). Eat other, simpler, more complicated-flavored really tasty foods for a while, and that becomes more obvious.

Ridiculously calorie-dense, indulgent foods are still delicious and easy to over-eat. But only really good ones. I make an amazing tiramisu (not vegan, but I'm ovo-lacto for 44+ years now, so it's OK), and quite an excellent carrot cake with cream cheese frosting. I could eat the whole thing, easily. Ditto for home-made (or good bakery) baklava (<== can be vegan).

Like Aaron said, the demonization of "bad" food and righteous recent conversion to "whole foods" will also have a psychological effect.

I'll bet the best vegan desserts - think concoctions with nuts, coconut, dried fruits, maybe (non-milk) chocolate, etc. - are still pretty delicious. They're also very, very calorie dense.

Not because of going vegan no, but I did go on a no added sugar steak for 3 months to break the yes habit when offered sweets.
These days I think most sweets are sickly sweet specifically if they are commercially made. I simply think they taste awful and won't eat it because of that

Do you want me to finish the packet for you?

Repulsed? That's a bit of a...dramatic...reaction to a cookie.

I think if you ate six of them you didn’t hate them that much. I mean, it’s not something you eat for health benefits so if you truly round them “repulsive” you wouldn’t have forced them down. You aren’t six and being told “you sit there til that broccoli is all gone or I’ll be serving it to you cold for breakfast”

I would not be “happy” that foods that I enjoyed suddenly repulsed me so much that I could only eat 6 of them (which by the way is 3 servings of Oreos so not THAT repulsive). I would be sad that I wasn’t able to consider context and dosage and big picture of my overall diet.

There’s an entire thread here about foods people liked as children but don’t like anymore. Those tastes generally don’t change in a week, and I don’t think any of us sit around eating a half dozen of the things we don’t like anymore.
