Controlling obesity should start with lifestyle changes

In real life, many people complain that they gain weight without knowing it. So, what are the factors that cause obesity? Wu Liangping, chief physician of the Guangzhou General Hospital of the Guangzhou Military Region, said that in addition to genetically-induced obesity, some factors in daily life are often the cause of obesity.

In recent years, scientists have been tirelessly studying the "obesity gene". We also found that many obese patients have a family history in the clinic, and scientists are increasingly determining that many obesity is caused by genetic genes. To date, more than 200 genes or chromosomal regions related to obesity have been discovered. Many of these obese genes start to function during the fetal period, and the external environment will accelerate this effect.

So, what are the factors that cause obesity in daily life?

Wu Liangping introduced that improper diet is an important cause of obesity. This is mainly reflected in two aspects: On the one hand, the appetite is too large. If you eat too much, you can't burn calories, which makes you fat. The other is uneven nutritional intake in the daily diet. First eat too much food with high fat and sugar content, such as regular consumption of fatty meats, fried foods, processed meats, many sweetened foods (such as baked goods, biscuits), sugared fruit juices, soft drinks, alcoholic beverages and refined processing High-carbohydrate foods such as rice noodles, etc .; secondly, insufficient nutritional intake of protein, vitamins, and cellulose. Such a diet structure may easily lead to excessive calorie intake, secondly, it may lead to insulin resistance, and thirdly, it may cause imbalance of intestinal microorganisms. These are the mechanisms that cause obesity.

Lack of exercise, too little physical activity, less calories, and naturally easy to obesity, especially after people reach middle age, the amount of physical labor gradually decreases, fat often accumulates on the abdomen and buttocks. In addition, people with less exercise will have a lower basal metabolic rate, and a lower basal metabolic rate will make the human body less capable of consuming calories and tend to gain weight.

Lack of sleep can increase the secretion of somatotropin, a hormone that stimulates appetite; it also causes a decrease in leptin secretion, which is a hormone that suppresses appetite.

Psychological factors can cause stressful eating. When the mental stress is high, the feeding center will be particularly excited, it will be difficult to achieve satiety, and people will continue to eat. Under the action of the cerebral cortex, the purpose of eating is not to obtain a heat card, but to obtain a mood of pleasure during the eating process, so it will continue to eat. In addition, when people are stressed, they will be prone to lack of sleep. In the long term, human hormone secretion will be disordered, and sugar and fat will not be easily consumed by metabolism.

Some medications can also cause weight gain. These include atypical antipsychotics (especially olanzapine, quetiapine and risperidone), anticonvulsants and mood stabilizers (especially gabapentin), hypoglycemic agents (such as tolbutamide), and rheumatoids Glucocorticoids and some antidepressants for osteoarthritis. It can be seen that obesity is closely related to our living habits, and controlling obesity should begin with changing lifestyles.
