lots of good comments here... I second eating when you feel hungry, not when you're supposed to, and also eating MORE often. In "Body For Life" (my husband did this and dropped 30 or so pounds, pre-biking) they say to eat 6 meals a day. The difference is they are little meals, You eat a lot, seems like all the time, but you are rarely hungry.

I find another key to eating right is having the right foods around. The more processed and prepped, the worse they are for you, almost always. We make sure to get lots of basic building blocks (fruit, yogurt, cheese, cereals, etc). If we have the good stuff around, we'll eat it, you know?

And we spend some time during the week to make foods that we can freeze, for fast lunches and dinners. Chilis, homemade mac and cheese, veggie soups etc.

We have a ton of single serving size containers (the reusable/recycleable kinds that are very inexpensive, so if they do break we don't mind). We never have enough of them. It's great because I can open the freezer in the AM and grab a meal for lunch. We especially like to make food from in season local produce, then in the wrong seasons we get a special treat of the local goods!

I've also taken a stash of food to work, so I don't need to resort to vending machine snacks or other goodies that frequently appear (candy, pies, ice cream, chips etc ...) in the work setting.

For deserts we get fruit popsicles or freeze jello & fruit cups. Better for you than ice cream.

It's actually not that hard to do, once you have a bit of a plan. But making the changes can be daunting at first. I am much happier with the way we eat now.
