sleep dietCutting calories and exercising in the gym may be the most known ways in losing weight. But you may want to start counting sheep in addition to calories to lose weight more effectively. A study conducted by Columbia University's Mailman School of Public Health and the Obesity Research Center has found out that lack of sleep is linked with risk of being obese. No wonder that obesity rate is growing everywhere, I notice that people sleep less and less nowadays.

The study discovered that people who slept less than four hours in a night were 73% more likely to be obese compared to those who slept between seven and nine hours. As a comparison if you usually have five hours of sleep then you are 50% more likely to face obesity risk compared to those who sleep eight hours a day. Lack of sleep disrupts your body metabolism processes and will make it more difficult to lose weight.



As quoted by this source, the culprit of this sleepless obesity phenomenon dated back to the prehistoric era where our ancestors were used to sleep less during summer and ate as much as they can in order to stock food to face the winter ahead. Although that sounds too far fetched, judging from my past experience, I tend to crave more for sugary stuffs if I slept for less than 7 hours. It felt like my body was searching for more energy in order to compensate with the lack of sleep.

Sleep deprivation causes a particular hormone named Cortisol to store the excess calories and store the calories as body fat. In a layman's term, Cortisol controls your appetite and by sleeping less than you ought to, Cortisol will make you feel hungrier than usual. This explains why I craved for more foods whenever I haven't had enough sleep. Lack of sleep has also been linked with higher blood glucose levels, which triggers an excess supply of insulin to our blood and can possibly lead to diabetes or obesity. Getting enough rest is highlighted also in Body Clock Diet guide as one of the vital aspects in optimizing our body metabolism.

These nasty effects make it essential to get enough sleep so that our weight loss efforts can be more effective. Although the number of hours needed vary for each person, it's generally believed that six to eight hours is the general consensus. There's one bright side of this news. At least you can do more sex before you sleep so that you burn more calories!

    I never knew this but this is so true. I remembered that I always ate bigger portion of burgers whenever I slept for less than 6 hours.

    Quite true... esp by in the days when I stay up overnight to mug for my O'Levels ... was feeling very thirsty and hungry the whole night! LOL

    I really couldn't imagine sleep for less than 4hrs, that to me is a recipe for more problems than just increased risk of obesity!

    Wow! Sleeping has never been made an issue at weight loss groups I have been to. Seeing all those benefits written down really does show how important it is to successfully beat cravings.

    The thing I find strange is that because I exercise, I have found that I need less sleep anyway. Don't think this is causing any bad effects on me other than I feel fit and healthy.

    If I don't get enough sleep I don't have enough energy to even THINK about working out...

    Interesting post.

    Thank goodness due to my vegan diet I don't have a weight problem as I am one who rarely sleeps more than 4 hours every night especially now I am older.

    Well surprisingly this is true for myself and with a research backing it up I am convinced that a good rest is indeed vital. I have been told numerously that sleep is related to craving and weight loss but looks like a lot of people like me still don't have the time to sleep properly everyday. Some say it's not 'how long' do you sleep but 'how well' do you sleep.
