The causes that origin the obesity and overweight are different, being considered between the most important the bad habits of life (bad food and lack of physical exercise), and the state of anxiety. There are also other of second importance, like glandular disorders, the genetic factor, the good taste for food, the posture of people, etc.
the main causes of obesity are anxiety and bad food

Bad food:

accumulate 7,500 calories is to accumulate more

than 1 kg of overweight
It is the consumption of major percentage of calories than the organism can burn, causing a storing of fat tissue (adipose). This way, the capacity of storing fat of the individual in the present is a problem for health. Long ago when men were hunters, thousands of years ago, this capacity was used, because it wasn’t known when it was going to eat, and the hunters kept food in the organism and the accumulated fat served them for the periods of cold. Now all this is no longer necessary; now with all the technological advances we just eat the necessary to be able to live and not for accumulating fat in the body. People who, in this time, accumulate fat, they have a bad food, caused by bad ways of life. The bad food is to eat more than the necessary, generating the consumption of more calories than those of our body requires, causing a caloric imbalance, which allows that our body accumulates more calories; we have to remember that for each 7500 calories our body accumulates as excess, it’s increased 1 kg of weight, and this drives to a medical profile of obesity.

the junk food is friend of the obesity
The ingest of carbohydrates as cereals, bread, fruits, vegetables and proteins (fish, lean meat, poultry, and skimmed milk) takes that the body consumes the calories as energy, combustible and doesn’t accumulate fat or adiposity. On the other hand, the majority of calories, coming from the fats, are accumulated immediately in adipose cells, adding weight to the body. The sedentary ways of life of citizen people contributes to the increase of weight. The bad food comes mainly from junk food that our children eat, principally in industrialized cities, like those foods with many additives and preservants, foods with mayonnaise, ketchup, mustard, ajinomoto (settling in the organism, and forming cancer).
don’t eat foods with mayonnaise, ketchup, mustard
The bad foods also are generated in the social environment, the one that turns around the food and drink. The food has become a “prize” to the behavior; the food has become the “best close” for a good business; some religious reunions finish with a consumption of food (vigil, kosher, kashrut, liquids with full moon, etc.), so on.
not to the junk food

Physical Inactivity:

Another of the bad citizen habits in the big cities is the lack of physical exercise or the sedentary. A daily practice of 20 minutes of exercises, being running, swimming, playing with the ball, and so on, generates a burn of calories and, therefore, the remaining fats and little or nothing of obesity. It’s confirmed that physical activity is one of the major determinants of the use of the body energy. The fact of increasing the physical activity makes that the body has to use more calories, doing that the caloric balance would be more favorable for not presenting obesity.
20 minutes of exercises daily is sign against

obesity

Anxiety:

It’s another of the important factors of the obeses due to the great anxieties for eating. The anxiety generates that the digested food would be easily assimilable, being developed an overfeeding in the person. The anxiety generates more appetite, more desires of eating. If we see it from another point of view, people opt for the easiest, the most delicious, and what is more approachable, this means, junk food.
develop anxiety is to develop obesity, ¡control

yourself!

Genetic factor, genetic obesity

Another important factor is the genetic factor, above all in children because it generates childlike obesity and overweight. The involved genes in obesity can be considered as predisposed and they can act generating obesity. The children of obese parents have 10 times more probabilities of being obese than the children of parents with a normal weight. For the cases of genetic obesity it is very important to do a control from the beginning, to avoid the troubles that accompany the obesity.

Another causes of obesity:

The posture of people is also another cause of obesity and overweight. The form of standing up and sitting down must be straighten but the muscles at being straighten they put pressure against the stomach, doing that the extra fat we have digested descends towards the lower part of the belly and can disappear normally. People in their great majority have a bad posture, when they sit down, they are felt tired, or they stay put in the seat generating and accumulating fats in the belly; also when they are standing up, they aren’t well straighten, they walk as monkeys with the back and head fallen forwards, this also generates fats in the belly.
the bad posture in people generates obesity

The metabolism of people is different one from the other. The energetic use of calories varies considerably between one people to another. Some people are more efficient about it is referring to the calories utilization to be able to keep the body temperature and to carry out the metabolic processes.
the bad functioning of the thyroid generates

obesity
The bad functioning of endocrine glands also generates obesity. They can be originated in the hypothalamus; for a disease of Cushing (high levels of cortisol); for hypothyroidism (decrease of levels of thyroid); for the syndrome of polycystic ovary; for deficiency of hormone of growth.
consume too much alcohol generates obesity
The application of antidepressant medicaments of tricyclic origin has demonstrated an increase of fat and an important winning of weight, presenting medical history of obesity. The long treatments by means of corticoids have demonstrated an increase of fat and of weight, also presenting obesity. Consuming too much alcohol also generates obesity.
the oral contraceptives cause changes of body

weight
The oral contraceptives are pills that contain feminine hormones. They avoid the ovulation and do thicker the mucus of the cervix to not pass the spermatozoids. Before using them, we recommend you to consult with a health specialist, although the fact is that, oral contraceptives produce disastrous effects about health, those that are systematically hidden to women.
The oral contraceptives are composed, generally, by the combination of estrogens derivate and by another derivate of progesterone, those that are produced an increase of weight. It is considered a secondary cause of obesity due to this is produced by other different to the overfeeding; it means, an obesity of secondary cause in major extent by the increase of the liquid retention, own effect of these hormones more with the increase of fat deposits. This increase of weight is limited due to it doesn’t continue until after have gained some few kilos but they are representatives. Furthermore, when it’s interrupt your treatment, you can see the lost of weight that is increased at the beginning of the treatment. Also, with the use of the derivates of these hormones more modern and the lower dose possible, it’s reduced in great extent this effect.
