Obesity is the excessive accumulation of fat in the body or obesity. Obesity occurs when individuals consume excessive calories than they need. Based on the results of the study, obesity can be influenced by various factors, including genetic factors, one part of the brain dysfunction, excessive eating, lack of movement / exercise, emotional and environmental factors.
It often happens that obese children from families in which one or both parents are also obese. This suggests that genetic factors play a role in determining the number of fat cells in the body element. By the time obese mothers who are pregnant then the elements of a large number of fat cells and exceeds the normal size, will automatically be passed down to her baby during pregnancy. Thus, babies born has an element of body fat was relatively equal.
Damage to one part of the brain.
Eat one's behavior is controlled by a control system located in a part of the brain called the hypothalamus. The hypothalamus is a collection of cell nuclei in the brain that directly relate to other parts of the brain and the gland under the brain. The hypothalamus contains more blood vessels from other regions of the brain, so it is more easily affected by chemicals from the blood. Two of the hypothalamus, which affects the absorption of food, namely the lateral hypothalamus (HL) which drive the appetite (early or feeding center); ventromedial hypothalamus (HVM), which served inhibit appetite (termination or satiety center). From the result showed that when HL damaged / destroyed then the individual refuses to eat or drink, and will die, unless forced to be fed and watered (given intravenously). Meanwhile, when the damage occurred in the HVM then someone would be greedy and obesity.
The pattern of overeating.
Overeating patterns tend to be owned by persons who are overweight. People who are overweight are usually more responsive than with people who have normal weight for external hunger cues, such as taste and smell of food, or time for a meal. They tend to eat when she feels like eating, not eating when he was hungry. Excessive diet is what causes them difficult to get out from obesity if it does not have self control and a strong motivation to lose weight.
Lack of movement or lack of exercise.
Body weight is closely related to the body's energy expenditure. Energy expenditure is determined by two factors: the level of activity and sport in general and basal metabolic rate or energy level required to maintain minimal function of the body. Of these two factors, the basal metabolism has the responsibility of two-thirds of the normal energy expenditure. Although physical activity only affects one third of energy expenditure in normal weight, but for people who are overweight physical activity has a very important role. When the exercise calories burned, exercise more often, the more calories you lost. Calories indirectly affect the basal metabolic system. People who work with sitting all day will decrease the basal body metabolism. So exercise is very important in weight loss because it can not only burn calories, but also because it can help regulate the functioning of normal metabolism.
In some cases of obesity stems from emotional issues are not resolved. People who have problems making the food as an escape to vent his problems. Food is also often used as a substitute for a substitute for other satisfaction is not achieved in his life. By making food as an outlet for the settlement of the problem is not matched with sufficient activity will lead to obesity.
Environmental factors also affect a person turns out to be fat. If someone raised in an environment that considers fat is a symbol of wealth and beauty of the person will tend to become obese. During the views are not influenced by external factors so that obese people will not experience psychological problems in relation to obesity.
