ByDaniel Pascoal

People who are fat are said to be susceptible to diseases such as hypertension and diabetes, and there are many people who have an image that "being fat is unhealthy and what is thin is healthy". However, there are many studies that produce results that "overweight / obese people live longer"Obesity paradoxIt is called. What is really what the obesity paradox has become a big controversy yet, what's news siteQuartzIt shows a very interesting view.

There are many researchers currently supporting "obesity paradox" that "overweight" that should hurt the health protects people from numerous diseases such as pneumonia, cancer, hypertension, heart disease etc.

It was 2012 that the obesity paradox became a big controversy. In general overweight diabetic patients may be advised as "weight loss of insulin", but professor Mercedes Carnethon of Northwestern University examined the data of diabetic patients and found that patients with standard weight The annual mortality rate was 284.8 people per 10,000 people, whereas the annual mortality rate of overweight / obese patients was found to be 152.1 per 10,000 people. After that, I examined the data separately for smokers and nonsmokers, but the results did not change, the obesity paradox that "those who are fat rather than those who are thin are lower in mortality rate" are certainlyI found out that it exists.

Also, in 2013 Professor Katherine Flegal of the American Center for Disease Control and Hundreds of HundredsWhen examining the results of mortality analysis, The lowest mortality rate isBody Mass Index(BMI)It is understood that the degree of obesity by people falling under 1 or 2. BMI is a body mass index representing the degree of obesity of a person calculated from the relationship between body weight and height, and is generally BMI value 25 or more and less than 30 and obesity degree 1, 30 or more and less than 35 and is considered to be degree of obesity 2.

However, it is true that it is difficult for people in the group with obesity levels 1 to 2 to suffer from diseases such as heart disease, but on the other hand, there are various factors that cause heart disease, between weight and disease Because there was a strong relationship in severe obesity was a person corresponding to severe obesity, the only thing that can be said at the moment is that there is a health benefit "being a little fat."

Professor Flegal's research is thoroughly examining as many as 3 million data, famous medical journalJournal of the American Medical AssociationAlthough it was also posted, some people refute the results of this research. Harvard Public Health CollegeWalter WilletteThe professorNPRRepresenting Professor Flegal's research as 'mountain of garbage' for the interview, I'm saying I am not worth reading. Professor Willet said after the above statementNatureAlthough he received a warning from the editor of the company, he also told Quartz 's interview that he also said that the research is "garbage".

Mr. Willet et al. 'S argument is based on the inappropriate comparison group used by professors Flegal et al. Opinions of opposition factions that the group of thinner people includes smokers and patients with chronic diseases, and the death rate is higher in the first place. In comparison with smokers and chronically ill patients, overweight people appear to be healthy, but on the other hand, studies on data from diabetes patients, studied by Professor Carnethon for smokers and nonsmokers separately It is also true that an obesity paradox existed even though it was.

In addition, French endocrinologist Boris Hansel analyzed the data of 54,000 patients at risk of stroke or heart attack, the best treatment for these patientsSympathetic beta receptor blockerYaStatinAlthough it was to drink, it turned out that people with mild obesity were able to protect themselves from illness without taking medicine.

If an obesity paradox is present, it is not necessarily said that "thinning is healthy", but what does it all mean "being healthy?"

The important thing here is "Health at Every SizeThe way of thinking. This means that eating properly and exercising leads to health, rather than focusing on weight loss and dietary restrictions.

The advice Paul McAuley State University of Winston-Salem State University gives people about health is "Please exercise." According to Professor McAuley who studies exercise over 20 years, many of the studies on weight and health overlooked the element of "exercise" or that he is approaching wrong. The data collected by Professor McAuley is said to indicate that exercise is strongly related to health and longevity than degree of obesity.

Some researchers argue that blood pressure and cholesterol should be more conscious than body weight, Professor Linda Bacon who studies nutrition at the University of California said, "We are sticking to weight as a means of keeping health" I have commented on it.

What the obesity paradox means has not been clarified yet in the study, and we do not fully understand the relationship between health and weight. In fact, even among researchers whose obesity paradox is seen in the results of their own research, there are some people negative to the view that "being fat is healthy". Professor Carnethon who examined the data of diabetic patients also saw the result that "obese people live longer than those who are thin" in a number of studies, but "the idea of ​​promoting weight loss in overweight diabetic patients I do not think I would like to cancel it. "

Professor Lavie also insists that it is necessary to maintain a proper BMI value as "the body of a lost person is perfect, but it may be a heart disease." But what is the problem is what the "perfection of the body" refers to, its definition is not clear. Even people of any body type can suffer from heart disease, people with fat heart disease may live longer than those with weight loss heart disease. The obesity paradox controversy comes down to what "standard weight is" in the first place.
