Here's a snack that ought to stop you from, well, snacking: whole-grain bread dipped in olive oil.

That's because olive oil is rich in a special appetite-controlling kind of fat. Wow, a fat that may help with weight control! That's something to write home about.

Getting the Message
Olive oil contains oleic acid, a monounsaturated fat. Upon reaching the small intestine, oleic acid triggers the production of oleoylethanolamide (OEA), another fatty substance. OEA then finds its way to nerve endings that carry a hunger-curbing message to the brain. And that message is loud and clear: "Hey. Stop eating! You're full!!" Researchers are hoping that new appetite-suppressing drugs using OEA will be developed to reduce obesity. (Get the skinny on why belly fat is so bad for your health -- and how to lose yours.)
