ajhoover Posted September 2, 2009 Share Posted September 2, 2009 I recently came across an article that discussed the link between having enough sleep and maintaining a healthy weight. There are two hormones, ghrelin and leptin that help control appetite. When you do not get enough sleep, levels of ghrelin, which increase huger, rise. Consequently levels of leptin which promotes the feeling of fullness, lower. In addition to creating an imbalance in ghrelin and leptin, sleep deprivation causes the levels of stress hormones to rise which increases cravings for high - calorie comfort food. The brain secrets growth hormone during the deep sleep phase, helping the body convert fat to energy. The average adault needs five 90 minute sleep cycles per night, so around 7.5 hours is a good goal to shoot for.Andrew Link to comment Share on other sites More sharing options...

ajhoover Posted September 3, 2009 Author Share Posted September 3, 2009 It is out of a paper bound journal so a link is not going to work. I can try and locate it for you, but i doubt the name would be much help. Link to comment Share on other sites More sharing options...

Blairbob Posted September 8, 2009 Share Posted September 8, 2009 Maybe "Lights Out, Sleep, Sugar, and Survival" http://www.amazon.com/Lights-Out-Sleep-Sugar-Survival/dp/0671038680 Link to comment Share on other sites More sharing options...
irongymnast Posted September 8, 2009 Share Posted September 8, 2009 Thanks Blairbob, but I meant it as "resource that contains information on the hormones that the human body produces", what each one does, how can it be limited/increased etc.Not specifically for sleep.

rubadub Posted September 14, 2009 Share Posted September 14, 2009 Also on the topic of sleep is this BBC article, about eating before sleeping making you put on weight.http://news.bbc.co.uk/2/hi/health/8234386.stm Link to comment Share on other sites More sharing options...
Garrett Smith Posted September 14, 2009 Share Posted September 14, 2009 Also on the topic of sleep is this BBC article, about eating before sleeping making you put on weight.http://news.bbc.co.uk/2/hi/health/8234386.stmwww.hibernationdiet.comA different perspective. I'm experimenting with the general concept (tablespoon of raw honey before bed) right now. Link to comment Share on other sites More sharing options...
Edward Smith Posted September 15, 2009 Share Posted September 15, 2009 Garrett,Could you explain the rationale behind it?An interesting aside, Dr Eades (I believe it was him) recommends taking a 5g dose of carbohydrates prior to bed if you are having trouble sleeping on a low-carb diet.Ed Link to comment Share on other sites More sharing options...
