sleep deprivationA new sleep study at the Annals of Internal Medicine shows that sleep deprivation has a negative effect on fat cells.  Specifically, a lack of sleep causes an irregular response by insulin.  It was determined that just like you, your fat cells get tired and don’t work properly without sleep.

The study determined that insulin sensitivity was 16% less responsive in a sleep deprived state.  Sensitivity of fat cells to the insulin dropped by as much as 30%.

Insulin resistance, such as this, is the cause of Type II diabetes.  With sleep deprivation so clearly linked to Type II diabetes and obesity, it’s time to start getting a full night’s sleep if you’re not already.

Not only does a lack of sleep make for a bad day at work or school, a lack of sleep might well be the reason you’re not seeing lean gains.
