Acute total sleep deprivation enhances brain activation in the anterior cingulate cortex in response to hedonic food stimuli, increasing subjective appetite ratings independent of fasting plasma glucose levels.

If you are sleep-deprived, your brain's reward system becomes hypersensitive to food cues, specifically activating the anterior cingulate cortex. This happens regardless of your actual blood sugar levels. To mitigate this, prioritize getting adequate sleep, as acute sleep loss directly amplifies the neural drive to consume food.

GoodSupportsHIGH confidence
Compared with sleep, total sleep deprivation was associated with an increased activation in the right anterior cingulate cortex in response to food images, independent of calorie content and prescan hunger ratings.
