Sleep loss means weight gain

Introduction

Experts have claimed for years that lack of sleep leads to weight gain. It has now been proved true. Not only does a sleep-deprived person eat more, he/she also tends to eat more fat and less carbohydrates. It was thought that hormonal disturbances were behind this, but a study says salience network, an area of the brain, is the key. The five-day-four-night study on 34 people, whose brains were monitored through MRI, found that sleep-deprived subjects had an increased connectivity in salience network. It has a key role in determining responses to hunger stimuli.
