How to become anorexic

Non-pathological causes of obesity or causes of simple obesity

To know how to become anorexic we should learn more about the Non-pathological causes of obesity i.e. causes of simple obesity

"Causes of Simple Obesity in adult people"

Really when we are speaking about how to become anorexic or how to lose weight, this means that we are speaking about the simple obesity. The pathological obesity is nearly out of our work in this website. We have only mentioned some information about the etiology and the features of the pathological obesity just to help differentiation between the simple and the pathological types. Some persons may be asking how to become anorexic or how to lose weight but they are not sure whether they have a simple or a pathological obesity.

A. Dietary causes of Simple obesity :

At its simplest, obesity is caused by an excess of energy intake over energy expended.

B. Genetic Susceptibility (Fat Storer).

Some experts estimate that as much as 70% of the predisposition to obesity is genetic. But this does not mean that the implicated genes must cause weight gain and obesity.

Our genes are switched on and off by many other environmental factors.

An ob gene is found on chromosome 7. This gene is expressed only in the adipose tissue. Its function is to produce a protein called "Leptin". This leptin acts on the hypothalamus making us becoming anorexic. In the obese person, this gene may be mutated, "ob ob", leading to the production of a nonfunctioning protein which is not able to act on the hypothalamus properly.

N.B. There are researches that show that human obesity leptin is not playing the major part in the pathogenesis of simple obesity.

C. Environmental causes of Simple obesity. The general model of life like activity model of the environment, sports, the formal physical activity in schools and in the university, TV watching, Cars, Computers, exercises in general, etc.

D. Neurological causes of obesity.

E. Physiological causes of obesity.

F. Biochemical causes of obesity.

G. Cultural and Socioeconomic factors.

H. Childhood causes of obesity :

Really the childhood factors may summarize many of the above non-discussed factors even for the adults. For example :

1- A child who is born at above average weight runs an increased risk of childhood obesity.

2- Breastfed children are less likely to develop obesity in adult life.

3- Chronic excessive intake of food calories, especially if starting during the early life, leads to activation of the adipose tissue cells to convert them into the hyper-cellular state increasing their capacity of fat storage. This may present the main cause on which many of the above mentioned causes are based on even the genetic factors! Yes, there are some researches which show that the hyper-cellular adipose tissue, resulting from the chronic excessive intake of calories, may be inherited, more or less, in the next offspring. This is still a part of Darwin  theory of evolution.!
