A little over half of America's population, 65% to be specific, is obese for many years now. Food chains, oily and fatty foods, jobs that don't require a lot of movements and even remote controls are the major factors of the so-called “obesity epidemic.” Stanford University and other research labs have just come up with a study that lack of sleep could be the one of the causes of weight gain.
When researchers at Columbia University studied the sleep habits and weight patterns of 6,115 people, they discovered that those who slept two to four hours a night were 73% more likely to be obese than those who slept seven to nine hours. People who slept five or more hours a night were 50% more likely to be obese, and those who slept six hours were 23% more likely to be obese. The researchers also found that those who got 10 or more hours of sleep a night were 11% less likely to be obese.
It appears in the study that falling short of an eight-hour sleep adds up the level of the ghrelin “hungry” hormones and lowers the “full” hormones, leptin. It's not that you can't help having a very full breakfast right away. You'll have a persistent feeling that you need to eat and when you do, you'll never get filled. Just the easiest way to obesity.
The thought that short sleep habits are to blame for weight addition goes a long way in explicating why new mothers can't drop off their “baby weight,” why college freshmen are notable for gaining the “freshman ten,” and why shift workers have more eminent obesity rates. A lot of people bear from habitual concern and strain that steps in with sleep, and as we get aged most of us build up aches and pains that can cause sleeplessness and cut off sleep.
The National Sleep Foundation estimates that 65% of Americans get less than the ideal eight hours of sleep per night. In fact, the average during the week is just 6.9 hours a night. Most people are able to get a few more hours on the weekends, but ghrelin and leptin don't seem to believe in playing catch-up. In a sleep-appetite study at the University of Chicago, those who slept four hours not only showed increased amounts of hunger-stimulating ghrelin (think “gremlin”), they also said that they craved high-carb foods like cake, ice cream, pasta, bread and candy.
To put it plainly, why suffer the agony of eating low-calorie food or go through a rigorous workout to lose weight when all you have to do is get more sleep? A successful weight loss therefore is to sleep early rather than watch televion which is near your refrigerator. The least that you can get from it is for you to feel more lively in the morning which can add up spice in your steps to burn those unwanted calories.
