In the study, researchers presented 12 healthy adults, ages 19 to 45, with photographs of low- and high-calorie foods over a four-minute period. Researchers found that faced with images of strawberry cheesecake, French fries, and other enticing eats, sleepier subjects exhibited lower activity in the prefrontal cortex — the inhibitory area of the brain Sleepiness May Impair the Brain's Inhibitory Control When Viewing High-Calorie Foods. American Academy of Sleep Medicine.

But do troubling food choices occur at sluggish or straight-up comatose states? In this study, participants weren’t chronically sleep-deprived. Instead, they displayed the usual tiredness that comes with staying up an hour or two past their bedtime. But this all-too-common behavior, data shows, can lessen inhibitory control enough to make it hard to say no to that extra cookie or slice of pie Sleepiness May Impair the Brain's Inhibitory Control When Viewing High-Calorie Foods. American Academy of Sleep Medicine.
