Fat Cells Need Sleep: The Relationship Between Sleep And Weight Management

It is well established that getting enough sleep is imperative to cognitive function and the regulation of hormones, and now researchers have discovered just how essential sleep is to weight loss and maintenance.

Sleep deprivation has a harmful impact on fat cells, reducing their ability to respond to insulin by 30%. The findings (published in October 2012) provide the first description of a molecular mechanism directly connecting sleep loss to the disruption of energy regulation in humans.

The negative impact on energy regulation occurred in subjects who slept for just 4.5 hours for 4 consecutive nights compared with those who slept for 8.5 hours. Keep your body primed for weight loss by getting enough shut-eye. The average adult requires 7-9 hours of sleep per night to function optimally.
