In a recent study researchers studied comparative energetics of both lean and obese adults to discover how everyday movements affect metabolism. Results showed that NEAT -- non-exercise activity thermogenesis , creates a more effective metabolism than standard organized exercise. Researchers say calories people burn during everyday activities are more important than previously thought. They say obese people sit, on average, about 150 minutes more each day and burn 350 fewer calories than lean people do.
20 participants were followed 24 hours a day with a movement-monitoring system that included embedded sensors in customized, data-logging undergarments. According to researchers the lack of NEAT in obese patients doesn't reflect a lack of motivation, rather a chemical difference in the brain. People with low metabolism have low NEAT, which means they have a biological need to sit more.
In conclusion researchers say , although NEAT appears to be fixed, doctors can use this data to help obese patients by focusing on energy as well as food.
