October 24, 2012 - People who consistently get too little sleep face bigger concerns than daytime fatigue and crankiness, Over the long term, sleep deprivation also increases the risk of serious health problems including obesity and type II diabetes. Various studies have shown, for instance, that how much we sleep can affect blood sugar levels, hormones that control appetite, and even the brain's perception of high-calorie foods. A small new study published in the Annals of Internal Medicine, adds that sleep deprivation, impairs the ability of fat cells to respond to insulin, a hormone that regulates metabolism and is involved in diabetes. Good news is, the treatment is fairly easy, just turn off the computer and go to bed earlier."
Also, researchers in Texas looked into the link between obesity and cancer and found fat tissue feeds cancer. They studied overweight and average weight mice, all with cancer, feeding them the same diet. The fat cells in the overweight mice helped form blood vessels that brought fresh oxygen and nutrients to the tumors and helped them grow.
