What causes us to be obese? University researchers found that genes, lack of sleep,
and even air-conditioning and other kinds of unexpected factors may affect your weight.

1.Sleep deprived: the greatest likelihood of obesity.

If people sleep less than 4 hours per day, resulting in the possibility of obesity is much
higher than those who sleep normal. Previous studies showed that lack of sleep and the
body's anti-obesity factors are interrelated. Sleep deprivation causes the body to promote
higher levels of appetite factor.

2.Friends: obesity can be "transmitted"

If your friend is fat, you may increase the probability of obesity. The reason is that, if their
friends or relatives of obesity, will change a person's acceptance of the standard of
reasonable weight.

3.Air conditioning: heat regulation mechanism is blocked

Because we always stay in air-conditioned constant temperature environment, so we do
not regulate body heat. If the temperature is low, our body will automatically burn fat to
keep warm.If the weather is very hot, and our appetite is reduced.

4.Hormone: control hunger

Scientists have also found that anti-obesity factor, is a major hormone used to reduce
hunger, which controls our food preferences. If people lack anti-obesity factor, would like
all kinds of food, and eat a lot, and eventually become super fat.

5.Influenza: the virus can increase the fat

The researchers found a virus causing the common cold can lead to obesity. In the
experiment, chickens and mice infected with a particular virus, weight gain than the
uninfected more quickly.The researchers found that the virus can rapidly increase the
body's fat cells.

6.Diet: It is still the key to fat or thin

Diet is a very important factor for weight. Most people gain weight is because their dietary
intake of calories than the body needs. If you want to lose weight 2 pounds a week, you
do not need a lot of calories every day, or to consume a lot of calories. You can eat less
and exercise more to achieve this goal. Therefore, understanding the weight loss
experience is very important.
