Those randomized to 8.5 hours of sleep a night lost significantly more body fat than those who got 5.5 hours. Getting even one more hour of sleep a night may help with weight control.
I should do more videos on sleep. In the meantime, you may be interested in:
• Do Mobile Phones Affect Sleep? (nutritionfacts.org/video/do-mobile-phones-affect-sleep/)
• Natural Dietary Remedy for Insomnia (nutritionfacts.org/video/natural-dietary-remedy-for-insomnia/)
• Melatonin Supplements for Sleep and Anti-Aging? (nutritionfacts.org/video/melatonin-supplements-for-sleep-and-anti-aging/)
This video was based on the sleep section in my book How Not to Diet, which you can see here (nutritionfacts.org/book/how-not-to-diet/) (all proceeds donated to charity), or check out my presentation based on the book: Evidence-Based Weight Loss (nutritionfacts.org/video/evidence-based-weight-loss-live-presentation/).
The “social jetlag” information I mentioned can be found in The Metabolic Harms of Night Shifts and Irregular Meals (nutritionfacts.org/video/the-metabolic-harms-of-night-shifts-and-irregular-meals/).
