We all know the importance of diet and exercise when trying to lose weight, but now it seems you need to increase your beauty sleep as well.
New research has found that not getting enough rest has been directly linked to overeating.
Scientists carried out tests to determine whether not getting enough shut-eye means you pig out the next day - and they found that both men and women ate about 300 calories more when they were sleep deprived.
The quizzical scientists took healthy men and women to a sleep lab where they manipulated the amount of sleep they had over a course of several weeks.
The researchers not only monitored what the participants scoffed afterwards, but also took blood tests to determine how the altered sleep affected their glucose, insulin, leptin and other hormone levels, which all play a role in the signals the body gives that it is hungry.
The results published in Sleep journal concluded that whilst different hormones were affected in men and women, the end result was the same - they both felt more hungry when they were tired.
Seems biology is trying to trip up our weight-loss plans by making us see food differently when we don't get enough rest.
"Our results point to the complexity of the relationship between sleep duration and energy balance regulation," study author Marie-Pierre St-Onge, a research associate at New York Obesity Research Centre at Columbia University explained.
