Sleep deprivation has a direct link with increased cravings for high calorie foods and may impair our ability to say no to junk foods.
A study by Greer, Goldstein and Walker (2013), examined the brains of 24 participants after a good night and a bad night of sleep.
The study showed that areas in the brain which are responsible for complex decision making may be impaired following sleep deprivation, which make it harder for the sleep deprived to make healthy food choices. In addition, areas in the brain associated with desire and motivation are increased.
Further to this, the study showed that sleep deprivation causes greater cravings for high calorie foods.
Moral of the story? Get a good night's sleep and you may find it easier to say no to temptation and stay on track with healthy eating!! Are you getting eight hours sleep per night? Do you find it hard to say no to that afternoon chocolate bar when you're tired?
