What's the connection between sleep and weight loss/gain? Well, there seems to be a whole lot of different opinions out there on the subject. However, they all seem to have a common thread.
Those who sleep between 7 and 9 hours a night, will have a much better chance of losing weight, and keeping it off. For those who sleep less then 7 hours a night, you have a 30% higher chance of obesity.
Scientists are still trying to track down the exact cause, but it seems that the lack of sleep affects two important hormones in your body. Ghrelin is the hormone in your body that tells you you are hungry, and Leptin is the hormone that tells your body you're full.
For those who sleep less, there is higher levels of Ghrelin and lower levels of Leptin. Therefore, your body is being told to eat more and told to stop less.
However, for those people suffering from sleep apnea this is not always the case, sometimes it's actually reversed and the person can have abnormally high levels of Leptin, but the brain doesn't seem to get the message. Once sleep apnea is treated in patients, it is common for patients to naturally lose weight once sleeping patterns are restored.
Your challenge, should you choose to accept it is to try and get 8 hours of sleep tonight and every night! You need it, and so do I! (Wish someone told that to the cops last night when they swarmed my apartment building at 1am to arrest my neighbor!)
