Statistical findings: genetic factors inheritance is not only related to obesity but also related to wasting. If the mother is obese, the probability that her child will be obese is 75%, and if the mother is thin, the probability that her child will be thin is also 75%. What is inherited is not obesity, but a talent for surviving in a starvation environment A person with a genetic background of obesity or a tendency to suffer from obesity is more effective in his or her metabolism. That is, if in times of famine, very little diet will enable these people to survive. Genetically speaking, these people are more suitable to live in the famine years, and it can also be said that the long-term dietary deficiency makes these people acquire this genetic characteristic, which is the reason of “survival of the fittest”, and these people have “thrifty gene”. But when these people become rich for a short period of time, their diet is not only satisfied, but their calorie intake is also greatly exceeded, and then this “thrifty gene” makes these people store as many calories as possible, so these people are more likely to become fat. China’s long history of poverty has made most Chinese people acquire this “thrifty gene”, so in the past 10 years, the rapid improvement in living standards has made obesity and obesity-related diseases (such as hypertension, diabetes, coronary heart disease, etc.) become an important threat to people’s health. Ultimately or “keep your mouth shut, open your legs” At the same time, age with the growth of age, the metabolic rate in the human body will decline year by year, so the same diet the same amount of exercise in the 20-year-old is not fat, but by the age of 40 will be fat. Moreover, our physical activity is also declining with age. Gender is a very important factor. Men’s metabolic rate at rest is higher than women’s, so men need more calories to maintain their weight. Also the metabolic rate of middle-aged women decreases significantly after menopause, so women begin to gain significant weight after menopause. And men and women’s eating habits, the amount of food and exercise are different, so gender is also an important factor in determining obesity. The amount of exercise exercise people consume more calories, not easy to get fat. But some people intermittently engaged in a large amount of sports, may be a week or even a month only a few hours of exercise, the result is not to control the weight, but to increase the appetite. So regular exercise is what will give good results. Weight heavy people need more calories to maintain their weight than people who weigh less. For example, a person weighing 90 kg needs 2500 kcal per day to maintain his weight. If his daily calorie intake is lower than 2500 kcal, his weight will decrease, and when his weight drops to 80 kg, he will only need 2000 kcal per day to maintain his weight, and if he still gives 2500 kcal per day, his weight will go to 90 kg again. Moisture accounts for about 70% of the average adult body weight, so weight is not the only measure of thin standard. However, after understanding the principle of obesity, obesity is no longer terrible. Knowing that you are consuming more energy than you take in, you don’t have to get on the scale to know that you are losing fat!
