It’s a familiar routine. The day winds down, the house gets quiet, and suddenly the urge to snack appears.
Not always from hunger, but from habit, stress, or simply needing a moment to unwind.
New research presented at Digestive Disease Week 2026, led by Harika Dadigiri of New York Medical College, suggests this common behavior may have deeper health implications.
Drawing on data from NHANES and the American Gut Project, researchers found that both stress and meal timing play a key role in digestive health, reports Medical News Today.

When rhythm breaks
The study indicates that people experiencing high stress who also eat late at night are more likely to report digestive issues. The body is simply not operating at full capacity during late hours.
Our internal clock regulates digestion, metabolism, and hormone activity. Eating late can disrupt this system, affecting how the gut functions and how efficiently food is processed.
More than calories
The findings highlight that it’s not just about what you eat, but when you eat it. Timing becomes especially important when combined with ongoing stress.
Key contributing factors include:

Together, these factors can disturb the gut’s balance and its connection to the brain.
Small changes matter
Experts note that occasional late-night snacking is unlikely to cause harm. The concern lies in repeated patterns over time.
Aligning meals with your natural daily rhythm and managing stress may support better digestive health.
