It’s not uncommon to eat late at night. Perhaps you leave a concert or comedy show and have a hankering for some tacos, or you settle for whatever is open. Typically, the food you eat late at night, or even as a midnight snack, is not the healthiest. With new research stating that eating late at night may yield unwanted side effects, you may rethink your late night eating habits.
Studying The Impact Of Late-Night Eating
Study authors stated that they looked at three key factors associated with obesity risk and weight regulation during the study. These three factors included:
- Energy expenditure (calories burned)
- Appetite
- Molecular changes in fat tissue
In order to do this, they had 16 overweight or obese participants follow two meal schedules. The first schedule was an “early meal schedule.” The second one was the exact same schedule, only everything was four hours late. People ate at 5 p.m. for the first schedule and 9 p.m. for the second schedule.
During both sets of meal schedules, participants noted their hunger levels, gave blood samples and had their temperature and energy expenditure measured. Study authors also collected data from some participants’ adipose tissue (body fat). They were also very careful to eliminate any compounding variables with protocol, including what the participants ate and sleep schedules.
What Did The Research Find?
After reviewing the study findings, the study authors concluded that eating late is linked to obesity risk, especially in people who are already overweight or obese. When participants followed the later meal schedule, they woke up feeling hungrier, were less effective at burning calories, and had adipose tissue that displayed an increase in fat growth. Eating four hours later makes a big difference for hunger levels, the way a person burns calories after eating, and the way a person stores fat.
Because the research only included overweight or obese participants, the study authors state that further research is necessary. Other studies are required to see if the results would translate to a larger population. Given that eating late at night can disrupt sleep and cause blood sugar spikes, though, it’s worth avoiding if you can help it.
The Takeaway
If you eat late at night, or find that you frequently eat a snack before bed, you may want to ditch that habit. Ideally, you should have your largest meal during the middle of the day for lunch and eat a lighter dinner. That way, the body has more time to digest the food you eat. Nevertheless, more research is needed to determine exactly what eating late does to the body. This study simply encored the fact that you should avoid large meals and unhealthy options late at night.
