If you're having trouble sleeping, it could be those excess pounds that are keeping you awake, notes the Nutri/System Health & Fitness Information Bureau.

According to Dr. Richard L. Atkinson of the Veterans Administration Center in Hampton, Va., many obese people suffer from sleep apnea, a temporary suspension of breathing during sleep, which causes an imbalance in the carbon dioxide and oxygen levels in the blood and causes the sleeper to wake, breathing at a rapid rate. The condition may occur hundreds of times a night.But breathe easy, a decrease in body weight usually helps relieve the problem quickly, Atkinson says.
