A study virtually presented at the Endocrine Society’s annual meeting found that people who started eating before 8:30 am had lower blood sugar and insulin resistance, reducing their risk of developing type 2 diabetes. Is done.
“People who started eating early in the day had low blood sugar levels, regardless of whether they restricted their diet to less than 10 hours a day or increased their diet to more than 13 hours a day. We found that insulin resistance was low, “said Mariam Ali, a senior researcher at Northwestern University in Chicago, Illinois.
Insulin resistance occurs when the body does not respond to insulin produced by the pancreas and glucose cannot enter the cells. People who are insulin resistant may be at increased risk of developing type 2 diabetes. Both insulin resistance and hyperglycemia affect a person’s metabolism, breaking down food into the simpler components proteins, carbohydrates (or sugars), and fats. Metabolic disorders such as diabetes occur when these normal processes are interrupted.
“With the rise of metabolic disorders such as diabetes, we wanted to better understand nutritional strategies that could help address this growing concern,” said Ali. Previous studies have shown that a time-limited diet that integrates the diet into a short time frame each day consistently shows improved metabolic health. Her group wanted to see if eating early in the day affected metabolic measurements.
The researchers analyzed data from 10,575 adults who participated in the National Health and Nutrition Examination Survey. They divided participants into three groups, less than 10 hours, 10-13 hours, and 13 hours or more per day, depending on the total duration of food intake. Next, we created six subgroups based on the start time of meal time (around 8:30 am).
They analyzed this data to determine if meal duration and timing were associated with fasting blood glucose and estimated insulin resistance. Fasting blood glucose levels were not significantly different between meal interval groups. Insulin resistance increased with shorter meal intervals, but decreased in all groups who started eating before 8:30 am.
“These findings suggest that timing is more strongly associated with metabolic measurements than duration and supports early dietary strategies,” Ali said.
