Study links “Social Jet Lag” to Obesity

The thought of sleeping in on a weekend excites most people, but in reality, sleeping in is often a rare occurrence. Yet, if a person wakes up at 6 a.m. Monday through Friday and sleeps until 10:30 a.m. Saturday and Sunday on a regular basis, the body’s internal (circadian) clock can be altered, upsetting the internal rhythm of the body, which helps you sleep soundly.

A recent study featured in Current Biology links “social jet lag”— what happens when your body is up later than normal, creating a sluggish feel the next day— to  unhealthy food choices and metabolism decrease over time.  A combination of a poor diet and slower metabolism can lead to weight gain and, over time, obesity.
