In my experience (which I've written a bit about at habitformed.com if you're curious), habits like these do become engrained if you keep at them long enough and if they specifically don't require any willpower. The key I've found is to take willpower out of the equation because you'll always be lacking that.

One way I judo'd my own eating habits was to force myself to eat two servings of decently healthy tasty things before being allowed a serving of junk. eg. some fruit, some nuts, then cookies. It didn't need willpower to enforce because I could always eat my way to a delicious cookie if I really wanted it.
