Scholars believe that in an era when food supply could not be guaranteed, human beings stored the calories they ingested to sustain life in order to survive; When the supply of food is sufficient, people will consume more food abnormally, forming an obese group.
2.Genetic factors. Obese people usually have a clear family history, the father or mother is obese, about 40%-50% of their children are obese, if both parents are obese, the chance of their children being obese can reach 70%-80%.
Studies of twin and adopted children have shown that genetic factors have a significant impact on obesity in humans, and that identical twins raised in different environments have no significant difference in weight, while non-twin siblings living in the same environment have significant weight differences. In addition, the weight of the adopted child is not significantly related to the weight of the adoptive parents, but is closely related to the weight of the biological parents.
Internationally, scientists' research on obesity-related genes has also confirmed that genetic factors are associated with the occurrence of obesity.
3.Neuroendocrine factors. The hypothalamus has two types of nerve centers that regulate feeding activity, a satiety center located in the ventromedial nucleus and a hunger center located in the ventrolateral nucleus.
If neuroendocrine disorders occur and the hypothalamus develops, polyphagia or anorexia can occur. Animal experiments have shown that after the destruction of the ventromedial nucleus, the animal eats more and becomes obese. When people are overly nervous, worried and sad, eating and drinking is suppressed; When you are in a good mood, your appetite increases.
4.Abnormal energy metabolism. Some obese people don't eat more than normal but gain weight, while others eat a lot but don't get obese.
Excessive diet was used to make normal weight people fat, and compared with spontaneous obesity people, it was found that 2700 kcal square meters of body surface area were needed to maintain the weight of the former, while spontaneous obesity patients only needed 1100-1400 kcal square meters of body surface area to maintain their body weight. In addition, to induce obesity with a high-fat diet, one person needs 4,703 kcal square meters of body surface area, while another person needs 8,417 kcal square meters of body surface area. The reason for this difference is that different individuals have different rates of energy metabolism, and lean people have the ability to consume energy in a thermogenic way, while obese people do not have this ability or have very poor this ability.
But in either case, you can change it through your own efforts.
