Laugh It Off, Pack It On
You’ve read over and over that cortisol is a stress hormone that can cause your body to gobble up your muscle—that even workouts are perceived by your body as stress, which increases catabolism. Reduce cortisol and you keep more muscle and make it easier to gain more and lose bodyfat. One way is to laugh more. Scientists at Loma Linda University in California found that even anticipating laughter can reduce cortisol by nearly half. No wonder your funny friends are your favorites.
