Too fat? Sleep more to reduce your weight!

Funny, huh? Sleep more to be slimmer! Yes, strange but true. Why? Because, our body burns some calories when we are sleeping. The more we sleep, the more calories burnt. But, of course too much sleep is not good for our health. We need to have the right sleep habit. At least, good sleep habit will help you maintain your ideal weight.

A study conducted by experts from Columbia university found the facts that people who sleep less than 4 hours every night have 73% tendency to overweight. The tendency is 50% for those who sleep 5 hours every night, and 23% for who sleep 6 hours every night.

Why is that? Another research from Obesity Research Center in Columbia and Mailman School of Public Health showed that those who don't sleep at night spend most of their time watching TVs or playing with their PCs. Guess what other things people use to do while watching TV or browsing the internet with their PC? Emptying their refrigerators into their stomach!

The more scientific explanation about this is: the lack of quality sleep makes our body produce too little leptin hormone that plays a key role in regulating energy intake and energy expenditure, including the regulation (decrease) of appetite and (increase) of metabolism. On the other hand, the production of grehlin hormone is increased. This hormone has the key role in regulation (increase) the appetite, that's why hungry people have a lot of grehlin hormone.
