Here's one reason you probably ate too much during the Super Bowl yesterday. Certain foods can actually make you feel hungrier. Here are four of them. And there's a decent chance you had all four yesterday. The Huffington Post did a story on this, and this is what we learned from it.

1. Processed foods. They make your blood sugar spike and then crash, which ends up making you feel hungry again before you really should. They also get the reward center of your brain all amped up, so you crave more processed food. Yeah, a vicious circle!

2. Alcohol. It lowers your inhibitions. So when you do get a little hungry, you're more likely to eat a LOT, or mindlessly keep snacking when you don't need to.

3. Artificial sweeteners. Studies have found anything sweet can increase your appetite. But your brain reacts differently to real sugar and artificial stuff. Sugar registers as a reward in your brain. Artificial sweeteners don't, so you keep feeling hungry.

4. Anything salty. A recent study found salty foods are so addictive, it's almost on par with a mild opiate. So that's one reason it's so hard to stop once you've started eating something like potato chips.

And of course, salt also makes you thirsty. So you end up taking in extra calories by drinking even more beer or soda.
