In the evening, the body becomes less effective at regulating blood sugar, according to EatingWell.
One reason is that the body’s cells respond less efficiently to insulin, the hormone that helps move sugar from the bloodstream into the body’s cells.
Research published in the Journal of Diabetes Investigation and Diabetes shows that the same snack can cause higher blood sugar levels in the evening than it would in the middle of the day.
The impact of sleep hormones
The body produces more melatonin in the evening to help us feel sleepy, but the hormone also affects insulin production.

A study published in Diabetes Care found that people who ate close to bedtime had higher blood sugar levels than those who ate earlier in the evening.
Researchers also point out that some people may be especially sensitive due to their genetics.
Better choices can help
Experts recommend choosing snacks that contain protein, healthy fats, and slow-digesting carbohydrates if you eat late at night.
Yogurt, nuts, fruit, and whole grains are considered better options than candy, chips, and other high-sugar snacks.

Overall, the research suggests that the body has a harder time processing food late in the evening because the circadian rhythm, hormones, and insulin all function less efficiently at that time of day.
