The Sleep Weight Gain Feedback Loop The latest study from Columbia University's researchers on the effects of mild sleep deprivation has sparked a timely warning: losing just 80 minutes of sleep per night for six weeks can lead to weight gain and increased sedentary behavior.
This moderate level of chronic sleep loss afflicts millions of Americans. Previous research often focused on extreme sleep deprivation, which is unrealistic for most people.
In contrast, this study examined adults who normally slept between 7 8 hours per night cutting back by about an hour and twenty minutes.
