Motivation, Anyone?

So...how do you motivate yourself to eat better?  I know how to eat healthy, all about portion control and good foods vs. bad foods, what I don't know is how to change my mind to go for the good instead of the bad.  Like Page and Amy are saying, I think its a habit that is in you, and I'm not so great at changing habits.  I've been working out everyday, doing good with that.  I can tell my body is changing, but I'm not losing weight.  It's because I still eat horribly.  On biggest loser the other night the trainers were saying that whole "I've gained muscle, that's why I haven't lost any weight" and "I've lost inches even if I haven't lost weight" thing is just an excuse designed to make us feel better about the fact that we didn't give it our all.  I thought about that and while I don't totally agree - we can look at Jorge's numbers and see that he's losing fat and gaining muscle - I do agree that if we aren't losing the weight we want to, we aren't doing something right.  First, I think its important to evaluate our goals to see if they are realistic.  More than 2 pounds a week really isn't.  Then I think we need to see how many calories we are actually eating each day and how many we actually need.  There are tons of places on the internet where you can do this, and if you have an iPhone or iPod touch you can download an app called "Fit Now" that does it all for you.  And it's free.  Anyways, I'm not controlling my food, and even though I'm exercising every day for at least an hour, I'm not losing weight.  I may be gaining some muscle, but until I start to control my eating better, nothing is going to happen!   Exercise alone can't do it.  To lose a pound a week, you have to burn about 3,500 more calories than you consume.  Most exercise burns 300-400 calories in one hour.  If I did that every day for a week, I've only burned 2800 calories, not enough to lose a pound.  So, if you've got tips, ideas, or personal stories about how to get motivated to eat better and less, let me know!
