Preventing Obesity Part 1: Adequate Sleep (Podcast # 19)

Dr Angelo Tremblay

UPDATE: Part 2 (mental work) is now online here, while Part 3 (nutrition) can be found here.

Two weeks ago Dr Angelo Tremblay gave a lecture at the Children’s Hospital of Eastern Ontario on preventing obesity in 2011 and beyond.  Dr Tremblay is a world-renowned obesity researcher, and is also the 4th most published obesity researcher of all time (amazingly, 2 of his Universite Laval colleagues are also in the top 4).  Dr Tremblay was so generous that he not only allowed me to record his lecture, but he also provided me with the entire powerpoint presentation so that I could share it here on the blog (big thanks also to Dr Jean-Philippe Chaput for facilitating both the lecture and its recording).

Over the next 5 weeks I will be sharing Dr Tremblay’s presentation through our podcast, and also as a Slideshare presentation.  If you would like to listen to the presentation on-the-go then I’d recommend the podcast.  If, like me, you are a visual learner, you can watch the Slideshare webinar below (I have synced the audio with the slides, so you can just sit back and relax!).  Each weekly section is around 15 minutes, so you can easily watch or listen during your lunch break if you are so inclined.

In today’s podcast, Dr Tremblay discusses the role of sleep in the development of obesity.  Among a number of interesting findings linking inadequate sleep and increased risk of obesity, he explains the surprising finding that sleep was the best predictor of childhood overweight and obesity in the Quebec en Forme study, as well as evidence from lab-based interventions which suggest that even one night of sleep deprivation can result in dramatic changes in hunger and foot intake.
