According to a new study, when we want something badly, the power of our desire can sometimes lead us to make strange, uncharacteristic choices. So if you've ever found yourself starving at a restaurant and ordering the double bacon cheeseburger with cheese fries, even though you were originally craving sushi and don't even like burgers, bacon or fries, there's a reason behind it. Your food cravings made you do it.

On the other hand, if you're turned off by food at the moment you decide what you eat, you tend to make more 'safe' choices. This makes sense -- it explains why we turn to comfort foods when we're feeling down.

Still, choosing things that we normally wouldn't isn't necessarily a bad thing ... it's good to add variety to your life every now and then. But take a moment to think about your choices -- especially the big ones.
