Overweight? Maybe You Just Don't Fidget Enough, Researchers Say
Pacing and wriggling during the day can determine whether one is lean, study concludes.

The difference between being obese or lean may be due to how much a person is apt to stand, pace, wriggle and shift about over the course of a day, a team of scientists reported in an intensive study of the consequences of fidgeting.
The researchers, who published their findings today in the journal Science, also suggested the amount of these mundane daily movements may be genetically ingrained — and that this would explain why some people could get away with being slouches without gaining weight, whereas others, ostensibly no more lazy, became plump.
Although this means some people are more likely to become overweight in today's sedentary society, it does not mean they are fated to, said the study's principal investigator, Dr. James Levine, a consultant endocrinologist and professor of medicine at the Mayo Clinic in Rochester, Minn.
The extra energy burned by the fidgety, lean group was about 350 calories a day — well within the reach of most people. The extra calorie burn amounts to at least 10 pounds a year.<snip>
Levine said that instead of a desk and chair, his office is outfitted with a treadmill mounted with a computer.
The treadmill is set at a leisurely 0.7 mph, and he now types as he strolls.
"I used to sit … 10 hours a day," he said. "Now I'm walking 10 hours a day."
