People who work night shifts may be able to avoid adverse effects on glycemic control by eating only during the day.

In a small study of people who simulated night shift patterns by staying up all night, those who ate only from 7 am to 7 pm had normal glycemic control after a single test meal. Was shown. In this regimen, people woke up and ate during the day, but refrained from eating during the night shift. However, as is often the case with people who work night shifts, those who ate at night had poor glycemic control.

Hyperglycemia damages blood vessels, so the body tries to keep it within a certain range, but if the level gets too low, the cells lack energy.Inadequate glycemic control can progress to Type 2 diabetes, Usually need to be managed with diet and medication, which can lead to heart disease.

Previous work found it Night shift worker It is easy to get poor blood sugar control and type 2 diabetes.Yes Frank Share At Brigham and Women’s Hospital in Boston, Massachusetts, his colleagues wondered if maintaining dietary patterns in line with people’s normal conditions could counteract their effects on blood sugar levels.Body clock“.

They asked 19 volunteers to eat a carefully measured test meal for breakfast, and then measured their blood glucose levels. Participants then gradually changed their awakening patterns, and after three days they had a completely opposite pattern and slept during the day. The next day, the group was split in two.

About half ate during the day and at night. This is the number of night shift workers’ actions. After that, I ate the same test meal for “breakfast” at 7 pm. Their blood glucose levels were 19% higher than after the same test was performed at the beginning of the experiment.

Others were fed only between 7 am and 7 pm and woke up a second time during the main sleep of the day to eat. There was no significant change in the glycemic response to the test meal.

Most night shift workers don’t like to wake up that day to eat, so his group says that people fit all meals, keeping them all meals just before and after sleep. I plan to test the new regime. Meals from 7am to 7pm. “The next step is to create a more practical meal schedule,” he says.

Working all night without a meal may be unpleasant, but eating small amounts may help and avoid carbohydrate-rich foods that raise blood sugar levels rapidly.

Jonathan Chederness At Uppsala University in Sweden, the results are interesting, but “based on this data, we do not know how these metabolic results will change if someone has a fixed night schedule for the week. “.
