It's not a good thing to be too cerebral about the whole "healthy eating" thing. That's because thinking about anything too much elevates it to mythical proportions. It's a good way to get stuck.
So factor in exercise.
It doesn't have to be vigorous ~ just moving in a way that gets you out of your head. The most effective way to make that happen is to do it when it's not convenient; when you have a million reasons why "tomorrow" would be better.
Psychologist Roger Mallot has said, "If you want to change your life, change one thing you do every day." That means when you pass by the cupboard where your Cheetos reside and reluctantly tie up your tennis shoes and head out the door for even a ten minute walk, you'll return with a different brain chemistry than when you left.
That will change even more the day after that ~ and even more the day after that. It's called "discipline" because you may not want to walk every day ~ or do yoga stretches, or ride your bike, or run ~ but you do it anyway.
As a result of that, your relationship with food changes because you've changed. You're less stuck. Then the choice between whether to eat an orange or a brownie gets easier.
