What causes Obesity?

Hardly anyone seriously believes that the real cause of the obesity is just the lack of willpower or the laziness that prevents a person to do sports. Although the causes of obesity are still not sufficiently studied, since the mid-1980s. it is considered a chronic disease, which is based on several factors.

Inheritance
Studies have shown that obesity is inherited. If one or both parents are obese, the likelihood of obesity in children increases significantly, especially because genes determine the body constitution and, to some extent - the weight. However, a predisposition to obesity does not mean that destiny of man sealed. The nature is debatable, if diet and exercise regularly. In some cases, with the aid of drugs or surgery.

Caloric food
Hot dogs, Big Macs, French fries, macaroni and cheese, potato chips, ice cream - all the popular meals are inexpensive, available and tasty. Not surprisingly, they have contributed to the spread of the epidemic overweight in many countries.

Lifestyle
The risk of obesity increases, if you sit a lot at your desk or on the couch. Similarly, the risk is higher if the fats make up more than 30% of your daily diet. Researchers found that people who dedicate 20-30 minutes for daily physical activity, are less prone to obesity. Best results are obtained by a combination of an active lifestyle and low calorie diet.

The metabolism
More specifically, the metabolic rate, or the rate at which your body uses the incoming food. With a low metabolic rate, the probability that the excess calories are stored as body fat increases. In this case, to fight obesity will have to exert more effort. However, these efforts ultimately may enhance your metabolism. Muscle burns more calories than the fat tissue, even when resting. Therefore, if reducing the consumption of fats and by using weight training to build up muscles, burning calories can be more intense.

Psychological aspects
There are people who tend to overeat (to have some kind of food "binges") in a stress condition or depression. Studies show that over 30% of obese people fall into this category. Therapists suggest that nutritional "binges" really can temporarily remove the stress caused by negative emotions. But then, after eating too much, comes the feelings of guilt, shame, disgust and begins depression.

Less Sleeping Leads To Extra Weight

The Columbia University and the Hospital of St. Luke-Roosevelt scientists published the results of the study, according to which there is a link between sleep duration and obesity.

Contrary to the public opinion, doctors have found that people who sleep less, are more exposed to the risk of gaining extra weight. Scientists watched a long time after a group of 18,000 patients and found: for those who sleep at night less than 4 hours, the risk of obesity is higher by 74% than for those who sleeps 7-9 hours. For those who sleep 5 hours - the risk of extra kilograms rises by 50% and for 6 hours sleepers - by 23%.

Most doctors give a simple explanation to this paradox: if people do not sleep at night, they eat, and there is usually little moving. Here is the general portrait of this less sleeping patients: a young man, sitting all night in front of the TV or the computer, with a few handy bottles of beer ( "cola", coffee, etc.), some snacks and a lot of sandwiches. Doctors recommend to abstain from eating after 6-7 PM, go early to bed and early in the morning to get up, nor to avoid moderate physical exercises throughout the day.

The blood hormones study revealed the fact that a small length of sleep caused a significant increase in leptina (the hormone responsible for feelings of satiety and reducing hunger), and, on the contrary, even more significantly reducing grelina (hormone which reinforces the sense of hunger). This makes the little sleeping people at night to feel hunger and insatiable desire to eat something rich in carbohydrates (pies, cakes, cookies, etc.), with all its attendant consequences.

Thus, the increase in duration of sleep can be seen as a means to combat obesity, not forgetting, of course, the leading role of regular physical exercises, and proper healthy nutrition.

The Obesity Virus

Scientists The University of Louisiana have found that obesity can be caused by a virus.

Even if a man is following a correct diet, many persons are missing the fact that every body is unique, and what's good for one may cause harm to another .

Scientists made an assumption that there is a virus that can affect human metabolism.

After some laboratory experiments it was showed that the infection with human adenovirus-36 (AD-36) - long time known as a cause of eye and respiratory infections in humans - causes adult stem cells obtained from fat fat tissue to transform into fat cells. the other stem cells (not exposed to the virus) remained unchanged.
The study also reported the identification of a specific gene that seems to be implied in the obesity effect.
