Sleep Deprivation Really Make You Fat?

Lack of sleep not only makes the body becomes weak but also can make us eat more. In fact, only a few calories burned. That is why people who sleep time is usually slightly more susceptible to obesity.
Although so far there has been no strong evidence regarding the mechanisms of obesity and sleep, but some studies did show that sleep should be a priority.
"If you want to maintain a diet for ideal weight, do not forget to have enough sleep because sleep is enough and quality is an important part of your body healthy," said Michael Grandner, an expert in the field of sleep disorders from the University of Pennsylvania, Philadelphia , USA.
Several studies of sleep and obesity has been done in a variety of methods. There are large populations surveyed and interviewed their eating and sleeping patterns and follow their health records. Other studies conducted on small groups of respondents in depth. The researchers also manipulated the schedule of respondents sleep and observe whether there are effects on appetite. In a recent study researchers from Sweden found in younger people who lack sleep seems nothing has changed on appetite, but their bodies burn calories 50-20 percent less than people who get enough sleep.
In her research, Marie-Pierre St-Onge of the New York Obesity Research Center and his team recruited 30 men and women in their 30s and 40s who have normal weight.The participants live and sleep in a sleep laboratory for five days in two different periods.
In the first period, the participants slept for 9 hours a night. The next period, they may only sleep four hours. In the second period, participants were given a calorie-controlled diet in the first 4 days and then released to eat anything in the last day.
Researchers want to know the energy you burn in daily activities and asked the participants how energetic they feel. Test results show no matter how many hours they sleep, the participants in the same amount of calories burned, about 2,600 per day.
But the group that lack of sleep, they eat more calories on the last day, about 300 calories. The participants also megnatakan they feel less energetic after a few days of sleep deprivation.
Researchers speculate that fatigue experienced by people who sleep less may cause them to make unhealthy eating choices. "When we sleep we will be more easy to follow self-will," said Grandner.
On the other hand, according to him, uncontrolled diet can also disrupt sleep patterns, such as the stomach so hard sleepy glut.

Fat men has few sperm

Being overweight has been linked to various health problems like diabetes and heartdisease. However, very few people realize that obesity also affects the quality and the production of sperm cells.

In a large-scale study involving 1940 men to the researchers found, as well as womenwhose weight is excessive, men who are overweight also have a smaller chance tobe parents because they are a little amount of sperm.

The researchers collected semen samples of volunteers and then measured the bodymass index (BMI) as an indicator of their obesity. Men who IMT was 18.5 to 25categorized as normal, including the BMI 23 to 24.9 overweight, and above 25considered obese.

The higher the excess weight, the lower the sperm quality, especially in men who fall into the category of obesity.

"Obesity will lead to modifications of sperm characteristics are due to hormonaldisturbances that make the quality, quantity and reduced sperm vitality," said Paul-Cohen Bacrie, scientific director of the network of European laboratories in his presentation at the meeting of the European Fertility Meeting.

Men who are overweight have a sperm count 10 percent lower, while the menclassified as obese in number 20 percent less. Addition of a group of obese menfound the number of men who have sperm levels of zero to four times more than in thegroup of men with normal weight.
