My Friend Ian Made Me Do It.

To Ian, A little bit of info about your Saturday night treat.

When you crave chocolate

What it says about your body: You reach for the chocolate because the flavor makes you swoon—but it does that because it stimulates the release of serotonin, Hirsch says. It’s basically an antidepressant in dessert form that your body instinctively seeks out when your happy chemicals are bottoming out and you need a quick lift.

What it says about you: That depends on what type of chocolate you long for.

• Dark chocolate: You’re the life of the party, a social butterfly and right in the mix of the team project at work.
• Milk chocolate: You’re the quiet, introspective type. Your idea of a perfect afternoon is a solo run or one-on-one time with a good book.
