As I mentioned at the outset, this is not a guide about what to eat. It's a guide about why we eat the way we do and how to do something about it. That said, I'll offer two suggestions regarding what to put on your plate.
1. Eat more greens. There isn't a consensus on the best diet, but pretty much everyone agrees on one thing: eat more veggies. You'll be hard-pressed to find a single diet that doesn't think eating more plants is a good idea.
2. Eat a variety of foods. As we covered earlier, the brain craves novelty. While you may not be able to replicate the crunchy/creamy contrast of an Oreo, you can vary your diet enough to keep things interesting. For example, you could dip a carrot (crunchy) in some hummus (creamy) and get a novel sensation. Similarly, finding ways to add new spices and flavors to your dishes can make eating healthy foods a more desirable experience.
Healthy eating doesn’t have to be bland. Mix up your foods to get different sensations and you may find it easier than eating the same foods over and over again. (At some point, however, you may have to fall in love with boredom.)
