I got suspicious of the article when it blamed obesity on excess sleep. I don't know that there is any clear scientific consensus in this area that proves more sleep is bad for you. The French sleep close to 9 hours: See eg. http://www.webinfrance.com/people-in-france-sleep-and-eat-the-most-says-oecd-617.html http://www.webinfrance.com/people-in-france-sleep-and-eat-th... so I don't see a direct correlation there with obesity rates. Sleep as long as you need. Your body and brain will tell you.
