Q. Can you give a personal example?
A. It used to be that if you put a huge plate of fries in front of me, I would eat it. Now I look at that huge plate of fries and say, “I don’t want that.” Sure, it will taste good, but in 20 minutes I’m going to feel lousy. For me, food has to be rewarding, it has to be pleasureable. But it also has to be nutritious, it has to satiate. It can’t just be fat on sugar on fat—that’s stimulating, but isn’t going to satiate.
