Late Bedtimes Could Lead To Weight Gain

Are you a night owl or struggle with going to bed early? Then you may be at risk for extra weight gain.

A recent study from the University of California, Berkeley found a correlation between sleeping and BMI in teens and adults who had a late bedtime on weeknights.

The researchers from Berkeley looked at data from a nationally represented group of more than 3,300 adults and youths. They found that for every hour of sleep they lost, they would gain 2.1 points on the BMI (Body Mass) index. The weight gain would typically occur over a 5 year period.  

This Study Looked At Bedtimes More Than Total Hours Of Sleep  

“These results highlight adolescent bedtimes, not just total sleep time, as a potential target for weight management during the transition to adulthood,” said lead author Lauren Asarnow, a doctoral student in UC Berkeley’s Golden Bear Sleep and Mood Research Clinic.  

The body mass index is a measure of your weight in kilograms divided by your height squared in meters. According to the chart, a healthy BMI for an adult is between 18.5 and 24.9.  

The data for this study came from the National Longitudinal Study of Adolescent Health, which has been tracking the behaviors and influences of U.S. teens ever since 1994.  

The people were placed into three groups: onset of puberty, college-age and young adult. The researchers looked at the BMI and bedtimes of teens from 1994 to 2009.

Surveys from the adolescents reported when they went to bed and how long they slept to the researchers. The researchers also collected their weight and height data so that they could calculate their BMI.

According to the surveys, many of the teens were not getting the recommended 9 hours of sleep each night. Many of the students reported that they had a hard time staying awake at school.  

Your human circadian rhythm, which regulates metabolic and physiological function, will often shift to a later sleep cycle once you hit puberty.  

Going To Bed Early Helps Reduce Weight Gain

The study suggests that teens and young adults who do go to bed early will “set their weight on a healthier course as they emerge into adulthood,” Asarnow said. Asarnow works on a program designed to help reset teens biological clocks, especially those who have trouble waking up or going to sleep at night.  

So, even if it isn’t easy, it may be well worth your time to retrain yourself to get to bed earlier so that you can reduce weight gain and stay healthy.

During my FitLife transformation, I lost 70 pounds! That's why I signed up for the protocol, but the most exciting result is that I found ME in the process. I had been hiding under a pile of pounds, self-doubt, and grief! FitLife changed my life and I knew I had to share it with others.

-Lynne, Longwood FL

I started with Fitlife back in 2011-2012…I wrote into Fitlife asking for an extreme amount of help. I was 300 pounds, with high cholesterol, and Drew helped me transform my life. I lost over 130 pounds and I no longer have high cholesterol. Not only did I lose weight, so did my husband, who lost over 70 pounds!
