Laugh it up
A recent study found that laughing out loud for 10 to 15 minutes a day can burn up to 40 calories. Not that that's a huge number, but over the course of a year, it could shave more than 4 pounds from someone who usually doesn't crack a smile. More importantly, laughter is your best weapon against stress, which can pile on pounds in multiple ways. Brain research shows that laughter overpowers the stress response (which is why so many of us laugh when we're nervous), and it reminds us that most of the nitty-gritty we worry about is not a matter of life and death.
