Do you have a goal to lose weight? If so, you're probably thinking about how you need to exercise more. And that can certainly help. But what about the 23 hours a day you're not at the gym? How much you move during those hours — from walking to the mailbox to fidgeting at your desk — can be just as important in winning the battle of the bulge. Here to explain the importance of what's called non-exercise activity thermogenesis, or NEAT, is Dr. James Levine, a professor, the co-director of the Mayo Clinic's Obesity Solutions Initiative, the inventor of the treadmill desk, and the author of Get Up!: Why Your Chair Is Killing You and What You Can Do About It. James explains how much more sedentary we are than we used to be and what happens to your body when, as the average American does, you spend two-thirds of your day sitting. He shares how doing the lightest kinds of physical activity, even standing more, can help you lose a significant amount of weight and improve other aspects of health, from your sleep to your mood. And we talk about how to easily incorporate more NEAT into your day.
