Lack of sleep linked to fatty food cravings

I’m sure I’m not the only one who has noticed when they are tired, they always want dirty, greasy burgers and hot chips. I always thought it was just me, but it turns out it’s just been scientifically proven that poor sleepers crave fatty foods.

A new study has been released that supports a link between sleep deprivation and fatty food cravings. Though it has long been assumed there is a link between sleep deprivation and the ways in which it affects our food choices, this is clear evidence.

Using MRI scans to track changes in brain activity, 23 participants underwent two tests – one after a full nights sleep and one after being sleep deprived for a night. The test subjects were then shown a range of portion sizes and pictures of 80 different food types.

Once the subjects were sleep deprived, the scientists noted there was impaired activity in areas of the cortex that assist with appetite and hunger levels. They also noted higher levels of cravings for high calorie foods.
