I haven't been sleeping well lately and a new study shows that's not good for weight loss.

Last night, I tossed and turned as I dreamed of former colleague Dennis Duggan, whose memorial service I had attended.

The night before, I had the always popular work nightmare. In this version, I was trying to update amNY.com to meet some sort of deadline and failed miserably. I woke up at 1 a.m., 3 a.m. and 4:30 before finally giving up on sleep at 6.

The only upside has been that since I'm up anyway, I've been working out nearly every morning.

But now comes news that sleep deprivation can promote weight gain.

Nanci Hellmich of USA Today wrote recently about a University of Chicago study monitoring the sleep of 30 men and women.

"So far, results of the study indicate that the short sleepers have an impaired ability to dispose of glucose using insulin, which may put them on the pathway to obesity," said the article.

Not good news for us who are struggling to get some Z's. See the complete article to get some sleep tips and take a quiz to see if you are sleep deprived.
