Blood Sugar and Your Internal Clock
You’ve heard it before, “Late dinners are bad for your health,” but do you actually know why? Recent research has strengthened the link between blood sugar and your internal clock, helping to explain why late dinners are potentially detrimental to your overall health.
A few definitions to consider first:
Frank Scheer of Harvard Medical School explains, “Our study underscores that it’s not just WHAT you eat but also WHEN you eat that greatly influences blood-sugar regulation, and that has important health consequences.”
Participants took part in two protocols: The first, the participants had their first meal (breakfast) at 8am and their last meal (dinner) at 8pm. In the second, their schedules were reversed so breakfast was at 8pm and dinner at 8am. In this version, they were scheduled to sleep during the day. Researchers measured levels of glucose and insulin at 10-minute intervals after each meal and hourly throughout the full sleep/wake cycle.
They found that glucose levels (lower glucose tolerance) were 17% higher in the evening than in the morning, independent of when a participant spelt or had their meals. They also found that simulated night work (sleeping during the day) lowered glucose tolerance throughout multiple days. The researchers believe that conflicting signals from the body’s internal clock may contribute to these effects of misalignment on glucose control.
The Next Step:
The goal with studies such as this is to develop and improve strategies for controlling glucose levels in day-active people and night workers. Scheer explains, “By better understanding the key factors that contribute to changes in glucose tolerance, we may be able to find better strategies to help mitigate the risk of diabetes for shift workers.
Ultimately, when food is consumed late at night, when our glucose tolerance is lower, the body is more likely to store those calories as fat rather than burn it as energy. Repeatedly eating late will ultimately lead to weight gain. Researchers are still reviewing WHY exactly there is a difference between how we process food in the morning and in the evening.
