Scientist have shown that sleep is vital to many aspects of our health. Now new research suggests that we can add maintaining a healthy weight to the list.

Research published in the May issue of Psychoneuroendocrinology shows that lack of sleep plays havoc with hormone levels, and may contribute toward weight problems. The study found chronic insomniacs have higher levels of ghrelin, a hormone that stimulates appetite. Levels of the hormone leptin, which promotes feelings of fullness, were lower. This could lead to tired individuals eating more during the day, causing weight gain.

If that wasn't bad enough, a lack of sleep boosts levels of the stress hormone cortisol, which gives rise to cravings for comfort foods high in calories. An undisturbed period of sleep is also important as the body uses this time to convert fat into fuel.  

The findings suggest that a good night's rest be included alongside moderate exercise and a balanced diet as the key to maintaining a healthy weight.
