Catch Some Zzz’s to Lose Some Pounds

Just the latest in a series of studies evaluating the effects of sleep on weight gain and obesity, a study from the University of Chicago, published in the Annals of Internal Medicine, found that insufficient sleep reduces the effectiveness of normal dietary interventions for weight loss.
 ..
Overall, a short night’s sleep significantly decreased the amount of body fat lost by 55% (3 lbs vs. 1.3 lbs with 8.5 hours vs. 5.5 hours sleep, respectively). Also, the loss of fat-free body mass significantly increased by 60% with 5.5 hours sleep compared to 8.5 hours (5.3 lbs vs. 3.3 lbs). Further, participants with 5.5 hours sleep experienced increased hunger compared to the group with more sleep.
