Obesity, the impact on human health has become increasingly concerned. Experts say that the lethality of obesity varies with BMI. a BMI greater than 32 can lead to a doubling of mortality. Obesity reduces life expectancy by an average of 6-7 years, with young, severely obese (BMI>40) patients under 35 years of age having a 20-year reduction in life expectancy for men and a 5-year reduction for women. Moreover, obesity can also lead to a variety of physical and psychological disorders. Experts warn that dietary and exercise therapy should be preferred for low-risk obese patients, and surgery can be considered for simple obesity BMI>32 or diabetes BMI>27.
Harm: obesity reduces life expectancy by 6~7 years on average
Obesity is lethal in the first place. Numerous American and European studies have shown that the lethality of obesity varies with BMI. a BMI greater than 32 can lead to a doubling of mortality. “The number of additional deaths due to obesity in the United States each year ranges from about 112,000 to 365,000.” Obesity reduces life expectancy by an average of 6 to 7 years, with younger patients under 35 years of age with severe obesity (BMI > 40) having a 20-year reduction in life expectancy for men and a 5-year reduction for women.
Obesity is also pathogenic and can lead to a variety of physical and psychological disorders. These diseases can be divided into two main categories: diseases caused by increased fat volume, including osteoarthritis, obstructive sleep apnea syndrome, and social disorders; and diseases caused by increased fat cells, such as diabetes, cancer, cardiovascular disease, hyperlipidemia, hyperuricemia, nonalcoholic fatty liver disease, and infertility.
”Obesity in the Asian population is dominated by centripetal obesity.” Centripetal obesity, also known as abdominal obesity, is mainly manifested as an increased waist-to-hip ratio and is an important risk factor for metabolic syndrome. The metabolic syndrome is a combination of a number of metabolic abnormalities, often including type 2 diabetes, hypertension, hyperlipidemia (hypercholesterolemia as well as hypertriglyceridemia), and hyperuric acid.
”An increase in fat content leads to a decrease in the body’s ability to respond to insulin, which leads to insulin resistance.” He said the current prevalence of diabetes in China is as high as 5.4 percent, which is already very close to the U.S. rate of more than 6 percent. In addition, the increased fat content likewise causes the body, mainly the blood, to be in a state of inflammation, increasing the risk of embolism.
Weight reduction methods: dietary and exercise therapy should be preferred for low-risk obese patients
How to reduce the risk of lethality and pathogenicity associated with the prevention of obesity? Wang emphasized that there is no other way, which is to reduce weight. And the principle of weight reduction is simple: control calorie intake and increase calorie consumption. Therefore, the simplest way is to control your mouth, open your legs, eat less and move more, which applies to all people who need to lose weight. Wang also used himself as an example to argue the effectiveness of this method of weight reduction. He said his weight once reached 190 pounds, which caused great inconvenience to his work and life. After making up his mind to lose weight, he has been insisting on controlling his diet and doing exercises, and after unremitting efforts, his weight has now returned to a normal level. “However, this method of weight loss requires quite a high level of willpower for dieters.”
A special reminder that to lose weight, you must slow down the pace of eating. “Normally, when the gastrointestinal tract feels bloated, it will send the “full” signal to the brain, and the cerebral cortex will send “full” instructions to the hunger center and satiety center, respectively, so as to stop eating. This process takes about 20 minutes.” He explained that if you eat too fast, and so the brain issued a “full” command, you have actually eaten too much. Therefore, the speed of eating must not be too fast, to avoid over-eating.
If diet control and exercise are not effective, you can also consider using medication under the guidance of a doctor.
There are two main categories of weight loss drugs: the first is the action of the central nervous system drugs, mainly through the suppression of appetite to achieve weight loss effect. This type of drug, such as sibutramine, has long been banned due to significant systemic side effects; the second category is the role of the gastrointestinal tract, through the inhibition of food absorption to achieve the purpose of negative energy balance, such as orlistat, the side effects of these drugs on the intestinal tract is more prominent, defecation or fart will have grease out, may leave grease stains on the pants.
”Weight loss through drugs, easy to rebound after stopping, and only for obesity and make the risk of disease increased patients,” he said, for low-risk obese patients, or should be preferred to dietary and exercise therapy.
Warm tips
People become fat and thin will conform to a law.
Dietary caloric intake and exercise expenditure = fat storage
Dietary caloric intake and exercise consumption = fat consumption
Thus, the following three factors determine a person’s fat and thin.
1. The presence of diseases that prevent the body from absorbing or consuming too much energy.
2, whether the dietary calorie intake is sufficient.
3, whether the amount of exercise is too much.
Many thin people always say, I do not have any reason, just can not eat fat, the actual is not seriously looking for reasons. The common reasons for not gaining weight vary from age to age.
