The Claim

In adults with overweight or obesity, late eating increases glucose exposure by 9% during nighttime sleep, and circadian biology amplifies metabolic vulnerability during rest periods.

How it works
1 study reviewed
In plain English

In adults with overweight or obesity, eating late at night causes a 9% higher blood glucose level during sleep, and the body's internal clock worsens this effect during rest.

See the scientific wording

In adults with overweight or obesity, the adverse glycemic effects of late eating are most pronounced during nighttime sleep, with a 9% increase in glucose exposure, suggesting that circadian biology may amplify metabolic vulnerability during rest periods.

Why this might work

When a person eats late at night, their body's internal clock signals that it is time to rest, so the pancreas releases less insulin right after eating, and muscles and fat tissue become less able to take up sugar from the blood. This causes blood sugar to stay high overnight, even though insulin levels do not change, leading to a larger overall sugar burden during sleep.

    When people with extra weight eat dinner late, their blood sugar spikes much more while they're sleeping than during the day—even if they eat the same food. This happens because the body’s internal clock makes it harder to handle sugar at night.
