The deficit of sedentary activity of participants did not necessarily reflect a lack of motivation, Levine said.

Instead, it could indicate a difference in the chemistry of the brain, because even when obese people lose weight, still leading a sedentary life. And when the thin gain weight, it nevertheless adopted sedentary habits.

The researchers studied ten subjects and ten moderately obese thin and dressed with a special underwear which used a technology developed for the control panels of the jets.

Distributed sensors that recorded underwear postures and movements of the subjects 24 hours a day for ten days.

Volunteers continued to wear their normal lives except that ate all their meals at a Rochester hospital and made sure not to leave food – calories – in their dishes.

In the next phase, the researchers increased 1,000 calories a day on meals of lean volunteers for 10 days, so that they could gain weight, while eliminating a thousand calories a day in the obese, that they might downgrade.

The study, published in the journal Science, was based on data compiled about the different levels of activity between overweight and lean participants.

To keep the figure are not just aerobics. U.S. scientists say the secret lies in changing the daily activities: climbing stairs instead of the elevator, hand wash dishes instead of using the dishwasher, walking instead of riding in a car or bus.
