(l) Heredity: In real life, it is often seen that many people in some families are obese. Some scholars have investigated the family history of obese patients and found that 34.3% of them have a history of obesity.
(2) Endocrine disorders: Obesity is closely related to endocrine function. Endocrine disorders are often accompanied by secondary obesity, such as increased insulin secretion in the body, low function of the anterior pituitary gland, hypothyroidism and hypogonadism. Encephalitis, brain injury, brain tumor or long-term injection of certain hormones often lead to obesity.
(3) Diet: People's eating habits and quality also have a certain impact on the occurrence of obesity. Improper pursuit of high-sugar, high-fat, high-protein diet, especially excessive intake of animal viscera and animal fat, good snacks, frequent drinking of beer, etc. , often lead to obesity.
(4) Mental factors: As the saying goes, the heart is broad and the body is fat. People who are in a good mood, have a good rest and are carefree often have a good appetite, eat well and eat a lot. On the contrary, if you want to drown your sorrows by drinking wine, you should drink wine, so that you can drink more and eat more, which can also greatly increase calories and lead to obesity.
(5) Less exercise: In modern society, due to the development of transportation and the mechanization and electrification of housework, physical activity is greatly reduced, which makes the supply of energy exceed the demand, leading to the imbalance between supply and demand of energy, which often leads to obesity. Some heavy manual workers have become light manual workers because of job changes; Or athletes stop their sports. In this case, if the diet is not adjusted accordingly, it will cause excess nutrition and fat accumulation in the body, which will lead to obesity.
(6) Physiological factors: After men reach middle age and women reach menopause, due to the decline of various physiological functions and physical activities, and the lack of corresponding reduction in diet, it is often easy to cause body fat accumulation and weight gain. Some women have better nutrition during pregnancy and lactation, and failing to participate in physical labor or physical exercise in time after delivery can also cause obesity.
(7) Environment: Eating a lot to keep out the cold in a cold environment can also lead to obesity. There are more opportunities to get in touch with food at work or at home, so there are more opportunities to eat and taste all kinds of food, which is easy to be obese, such as chefs and housewives.
