My husband jiggles his legs when he reads, and it looks like one of my daughters has inherited his "busy legs." I have read from multiple sources that this fidgeting pays off in burning calories. According to research performed by the Mayo Clinic, the leg jiggles as well as exaggerated hand gesturing can burn as much as 350 calories a day. They have labeled these wiggling motions "non-exercise activity thermogenesis," or NEAT.
While I think NEAT is neat, I am not one to take up this habit. The leg jiggle doesn't come naturally to me and while I do talk with my hands on many occasions, I don't believe I'm burning up too many calories. What about you?
