Lack of Sleep Reduces Impulse Control Necessary to Turn Down Junk Food
It sounds like a crazy idea. Get more sleep, gain less weight
The study from UC Berkeley found that after a poor night's sleep, the parts of the brain associated with automatic behavior were extra active, while the frontal lobes which affect self-control were more inhibited. The result? A groggy person will be more likely to do whatever their instinct says right in the moment, rather than make more conscious, healthy decisions:
"What we have discovered is that high-level brain regions required for complex judgments and decisions become blunted by a lack of sleep, while more primal brain structures that control motivation and desire are amplified."
Of course, the idea isn't exclusive to diet. A lack of sleep can affect any decision that you have to make consciously instead of instinctually. However, the researchers did find that the participants that weren't well rested had higher cravings for junk food.
