Is obesity actually a booster for COVID-19’s illness？ How many of the seven ＂obesity factors＂ do you account for？

　　"summer summer quietly came to fat only you, your girlfriend, your girlfriend as thin as Lin Daiyu … …” After hearing this song, do you have a heart-felt desire to stay at home and not eat less? Let me tell you a more heartfelt news. In addition to the "three highs" and chronic diseases, some foreign researchers have suggested that obesity is even one of the risk factors for COVID-19’s illness. What is it that others are not fat and you are fat? Today, experts from the Center for Chronic Diseases Prevention and Health Education of Beijing CDC will help you find out why.

　　Obesity may make COVID-19 worse.

　　According to experts from the Center for Chronic Disease Prevention and Control of Beijing CDC, obesity often occurs at the same time with diseases such as dyslipidemia, fatty liver, hypertension, coronary heart disease, abnormal glucose tolerance or diabetes, and can also be accompanied or complicated by obstructive apnea during sleep, gallbladder disease, hyperuricemia and gout, osteoarthropathy, venous thrombosis, impaired reproductive function and some cancers. Obesity may be the inducement and risk factor of these health problems, and may also have a common pathogenesis with these diseases.

　　However, some foreign researchers have suggested that obesity is even one of the risk factors for the aggravation of COVID-19’s illness, especially among young patients. American and French data show that among COVID-19 patients, obesity is associated with a higher possibility of hospitalization and serious illness.

　　You are fat if others are not fat? The reason is here.

　　According to experts from Beijing Institute of Health Education, in fact, 70% of human obesity is attributed to genetic factors, but obesity will happen quietly only with the joint promotion of mental, dietary and environmental factors. Why are you fat when others are not? Look at the following seven "obesity factors". How many do you account for?

　　hereditary factor

　　If both parents have normal weight, the probability of obesity in their children is only 8% ~ 10%; If one parent is obese, the probability of children being obese is 50%; If both parents are obese, the probability of obesity in their children will reach 80%.

　　Mental factors

　　There are two centers in the hypothalamus of human body, which control hunger and satiety respectively. Studies have found that excessive mental stimulation or nervous excitement, diseases and other factors can make these two centers dysfunctional and lead to obesity.

　　Endocrine factors

　　Many factors will promote the insufficient action or excessive secretion of insulin, leading to increased fat synthesis and obesity.

　　Dietary factors

　　First of all, overfeeding obesity is the main type of obesity. When the energy intake exceeds the demand, it is converted into fat and stored, which leads to obesity. The second is that I like sweets. The researchers found that with the increase of sugar, the proportion of overweight people and diabetic patients will gradually increase; The third is the number of meals. It is found that the probability of obesity, abnormal glucose metabolism, abnormal lipid metabolism and cardiovascular disease in people who eat twice is significantly higher than that in people who eat three times. Appropriately limiting staple food and putting fruits in snacks will be beneficial to the balance of energy and the onset and metabolism of insulin.

　　Insufficient exercise　

　　Due to the advancement of urbanization and taking cars instead of walking, more and more people are less active. For example, staying at home, sitting in a chair and not taking part in effective outdoor sports will undoubtedly reduce energy consumption, promote the formation of insulin resistance and receptor resistance, and lead to energy metabolism disorders.

　　Lack of sleep and disorder of biological clock

　　Studies have found that the obesity rate of children who sleep less than 7 hours will increase significantly. In addition, the circadian rhythm will also affect the energy metabolism and sugar metabolism of the human body.

　　Bad living habits

　　Although smoking has little effect on body weight, smoking can lead to severe insulin resistance, which will promote the occurrence of diabetes, hypertension and cardiovascular and cerebrovascular diseases. Drinking alcohol, especially eating a lot of high-fat food while drinking, can also lead to obesity.

　　Don’t be quick. It’s advisable to throw a catty of meat every week.

　　According to experts from the Center for Chronic Disease Control and Prevention, obesity begins with fat accumulation, and the reason for fat accumulation is that energy intake exceeds energy consumption. This also gives us two ways to fight obesity: reducing calorie intake and increasing calorie consumption. Simply put, it means "eat less and exercise more".

　　The "meat-throwing" advice from the World Health Organization is: limit the energy intake from fat and sugar; Increase the consumption of fruits, vegetables, beans, whole grains and nuts; Regular physical activity (60 minutes per day for children and 150 minutes per week for adults).

　　In addition, to lose weight, don’t rush for success. The speed of weight loss should not be too fast, and the weight loss goal should not be set too high. In the case of low-energy diet and moderate exercise, losing 0.5 kg per week is the ideal speed for healthy weight loss, and losing 5% ~ 10% of the original weight within one year will be beneficial to health. Moreover, to avoid "losing weight" in pursuit of "beauty of bones", the body mass index should be maintained at a normal level (18.5 ~ 23.9 kg/m2).

　　It is better to weigh yourself on an empty stomach in the morning before breakfast.

　　Weigh yourself "thin" immediately after eating, drinking a glass of water and even going to the toilet. Are you talking about it? In fact, it is not better to measure your weight as often as possible. It is ideal to measure your weight once a week. According to experts from the Center for the Prevention and Treatment of Chronic Diseases, it is normal for weight to fluctuate within a week. It is relatively accurate to maintain the frequency of weight measurement once a week and comprehensively evaluate the weight loss results in a short period.

　　In addition, a fixed time period should be selected for weight measurement. Every time you measure your weight, you should choose to wear the same clothes at the same time, in the same environment, and there is no big difference in your health. For example, after getting up in the morning, fasting before breakfast is a better measurement period, at which time it is less affected by eating, and the body is relatively stable after a night’s rest.
