I had a major sweet tooth. I would eat pastries every day, almond croissants, candy, cookies, chocolate, bread, ice cream. Couldn't get enough. Now that stuff tastes too sweet to me most of the time, especially if it's commercially-made crap. If a nice lady at work bakes a cheesecake or I have some ice cream, I can eat just a small amount and I'm fine, no desire to pig out on it. I can turn it down, too, and not feel deprived. Meanwhile, stuff like liver and onions or mangos or home-grown tomatoes give me mouthgasms. This way of eating tends to be self-reinforcing.
