We thought raiding the fridge in the middle of the night was a lack of willpower. Science has found the real culprit

Late-night eating is increasingly linked to chronic stress, not just lack of willpower or simple cravings.

Researchers tie nocturnal snacking to sleep disruption and changes in key hormones like cortisol, melatonin, serotonin, and dopamine.

The pattern may also affect gut health by altering the microbiota, making it a broader metabolic and digestive issue.

This reframes nighttime overeating as a health problem that may require stress, sleep, and metabolic treatment.
