Eating close to bedtime could interfere with your body’s ability to manage blood sugar, according to new research from the German Institute of Human Nutrition. In a study of 92 twins, scientists found that those who ate later in the evening had lower insulin sensitivity—a risk factor for diabetes and other metabolic issues.

The body’s internal clock, or circadian rhythm, is designed to handle food better earlier in the day. When meals happen too close to sleep, it may disrupt this rhythm and lead to worse glucose control over time.

Not everyone agrees that the findings mean you should avoid late meals altogether. Registered dietitian Destini Moody says blood sugar shifts are normal and manageable. Still, she recommends choosing whole grains, lean proteins, and fiber-rich veggies in the evening to help keep levels steady.
