　　Do you know what is the lifetime career for a woman?

　　Well, I won’t doubt who will know the answer better than you girls. Yes, absolutely it’s keeping slim!

　　As summer is approaching, it's time for us to shed some pounds before hitting the beach. The question is how to lose weight easily without suffering hungry or the tiredness of sports.

　　The good news came that consistently getting a good night’s sleep may be one of the answers according to some new researches. You may wonder what’s the connection between sleep and the number on the scale. Well, I will elaborate on it in two aspects.

　　First, getting a good night's sleep can prevent overeating and help curb obesity because sleep deprivation spikes the hormone ghrelin, which stimulates your appetite. Research published in the American Journal of Clinical Nutrition shows that people who sleep only about 5.5 hours per night take in significantly more calories from snacking throughout the day than those who are well-rested. That adds up to a tremendous 30 pounds a year. And they are comapatively dislike vegetables and crave carbohydrates and eat fewer proteins and fats,

　　which help people feel full.

　　Second, not getting enough sleep might severely cut into people's ability to lose extra fat, as the amount of the hormone, leptin that related to energy expenditure will sharply decrease without enough sleep. Researchers found that if dieters got a full night's rest, they lost more than twice the amount of weight from fat reserves. Tired-eyed dieters also reported feeling hungrier than they did when they had gotten enough sleep.

　　So despite any extra calories a person might burn while staying up, losing sleep is hardly the best way to lose fat. If your goal is to lose fat, skipping sleep is like poking sticks in your bicycle wheels.

　　In a word, it’s better for girls to make sleep a priority and get a beauty rest. Remember never to sacrifice your precious sleeping time next time you are indulging in some soap operas or talking on the phone, unless you want a larger number on the scale.
