10 Causes of Obesity

Obesity is defined as abnormal accumulation, or excessive fat, which may cause a health hazard. Whether a person is obese can be classified by using a body mass index (BMI) In kilograms per square meter in length, and a person is obese if the BMI is 30 or more, while the index is 25 or more, this is characterized by an increase in weight. Obesity and overweight are among the risk factors for many diseases Chronic.

Causes of obesity

There are many factors that cause obesity and obesity, and the most important of these causes include:

* Genetics: Obesity is associated with genetic factors; the risk of obesity is high if the parents are infected. However, this depends on other factors, such as the nature of the food. It was found that the rates of obesity in non-industrial cities increased after starting the Western diet, despite Of genes have not changed, but environmental factors have changed. On the other hand, studies have suggested that genes have an effect on weight gain.

* Manufactured foods: processed foods contain refined ingredients and additives, which are made to be delicious, cheap, and long-lasting to attract the consumer, and this leads to over-eating. Food, on the other hand, manufacturers of these foods may use many ways to increase the proportion of sales.

* Food addiction: Many high-fat processed foods and sugars stimulate the reward system in the brain. These foods can cause addiction in people who are so susceptible, as the patient loses control over his eating behavior.

* Insulin: Insulin plays an important role in regulating energy stores in the body. It stimulates the body's fat cells to store fat and retain the fat in it. It is worth noting that following the western diet may increase Insulin resistance The body in obese people, which leads to storage of energy inside the fat cells rather than to provide for use in the body, and many studies indicated that the high rate of insulin may be a cause of obesity, and on the other hand, it can be Low levels of insulin by refraining from eating simple sugars, refined carbohydrates, and increased intake of dietary fiber.

 * Some medications: Many types of drugs cause weight gain. Antidepressant, antipsychotics and diabetes drugs alter the body and brain functions by increasing appetite, Or reduce metabolic rate.

* Leptin resistance Leptin is produced by fat cells and increases in blood levels with increased body fat. Leptin levels are high in people with obesity. Leptin levels in healthy people are associated with low appetite, but it does not work the same way. In which case the blood-brain barrier, called leptin resistance, is not a cause of obesity.

* Sugar: Sugar can be one of the worst aspects of a modern diet. Excessive consumption leads to changes in hormones and biochemicals in the body. Its consumption is also linked to weight gain. Sugar is added to glucose and fructose. Glucose can be obtained from other food sources , Such as starches, but most of the consumed amounts of fructose is the source of sugar, and the consumption of excessive amounts of fructose can lead to insulin resistance, and increase in levels in the body, and does not enhance the sense of satiety, such as glucose, and because of these factors, Sugar added may contribute to increased energy storage, leading to obesity.

* Lack of physical activity: Most people now follow sedentary lifestyles because of the use of modern devices and transportation. Lack of movement may reduce the amount of calories burned by the body. Studies have shown that activity Physical activity has a positive effect on the regulation of insulin levels, as its instability may be associated with weight gain.

* Lack of sleep: One study has shown that people who do not sleep long enough are twice as likely to be obese; sleep deprivation stimulates the secretion of ghrelin, which increases appetite. On the other hand, Produce less leptin which reduces appetite.
