Obesity (overweight): is the increase in the stock of body fat a person is infected with obese if his weight (20
30%) more than the weight that must be it taking into account the age, height and sex.
There are many factors that lead to obesity and these factors:
First: genetic and environmental factors: scientific studies have proven the importance of genetic factors in the emergence of obesity. Scientists have managed to discover a gene called obesity gene or (ob.gene) of this gene produces a protein called (Leptin) that people with obesity have as an increase in the protein that is secreted by fat cells and fat stores and adjusts it to control the operations of hunger and satiety.
Second: food factors that physical level of the family, as well as provide special snacks and sweets may affect the method of taking food. There are some people eat larger quantities during sports training violent as well as women during pregnancy and then find these difficult to reduce from taking food after that and this leads to positive for obesity has been found that people with obesity eat more than they need with the passage of years, the increase small daily fat lead to the deposition of large amounts of fat and this leads to the emergence of obesity.
Third: in appetite control: appetite is the desire to eat it that lead to eating and after eating satiety happens. And satiety process depends on the fullness of the stomach and duodenum, Amtdadahma and also depends on the secretion of some hormones such as (Somatostartin) of the small intestine and insulin from the pancreas of all these hormones involved in regulating satiety in humans.
Fourth: power consumption: the reduction of exercise leads to a reduction of energy consumption and this leads to the deposition of more amounts of fat in the body and then the emergence of obesity
But how do we know that this person is overweight (obesity) first? There is a simple mathematical equation
Weight (kg) / height (m) 2
If the output of more than 25, it means that this person has an increase in weight and the more this class increased weight gain. If the output is less than 20, it means that a person has a decrease in weight. However, if the output (25 to 20), it means that the weight in the normal level that must be it.
That obesity or help lead to the emergence of many diseases including: diabetes .. Diseases of the heart arteries .. Stroke .. High blood pressure .. Inflammatory diseases knee .. Back pain .. Shortness of breath .. Disturbances in the menstrual cycle in women .. Mental illnesses as a result of weight gain.
In people with obesity may spread fat all over the body or may be concentrated more in the central region of the body ie the waist People who are fat have more in this region suffer from central obesity and this is the most dangerous disease linked to more and more dangerous.
Therefore should not be more than waist / hip circumference and one in men and no more than 0.9 in women.
The prevention of obesity is very important before treatment and must be the first goal because most obese people face great difficulty in maintaining their weight decrease, there are two ways to lose weight and these methods are linked with each other.
First: the control of food and this so-called diet or (Splenda) that the goal of any diet process is the loss of about kg per week.
It must be this process for a long time even lose man a large amount of fat to lose weight initially be faster because of the crash proteins and stores glucose with the loss of water, but after about 4 weeks, the weight loss is very slow due to the crash of fat without losing water. It must be recalled here that there must be food containing appropriate amounts of carbohydrates, proteins and fats, as well as all the important elements of the human being.
Second aerobics that the increase in exercise leads to an increase in energy consumption and this leads to weight loss and the importance of regular exercise they also lead to improvements in public health and help a person to control his food.
Some people with very obese and who may have fatal obesity and served them sport or diet may resort to some surgical procedures to lose weight and some of these processes have serious repercussions on the rights.
Finally, and generally advised not to use any drugs to lose weight because these drugs from the harmful effects on human health
