There are several reasons why people with excessive weight live longer than the average data for the country. The hospital staff at the University of Copenhagen noticed that in the past 30 years, the risk of premature death among fat people has become quite low. Clearly explain the nature of this phenomenon, scientists still can not. Preliminary results of scientific work published in the pages of the Journal of the American Medical Association.
Conducting statistical studies, the scientists concluded that the body mass index (the main index, which rates the presence or absence of obesity) has almost no connection with premature mortality. Note, we are talking about a relatively minor increase in body weight.
Apparently, the development of modern medicine has allowed most countries to reduce the risk of diabetes and diseases of the cardiovascular system. So fat people mostly live no less than thin.
