Fat people live longer and are less stressed

06.11.2012

According to a recent study conducted at the University of Göttingen, Germany, one in four is overweight. Such people have always been considered unattractive at high risk of disease dangerous to life.


Now scientists have discovered that overweight people are more resistant to stress and, therefore, live longer if they do not suffer from severe obesity.

On one hand, this means that more obese people tend to diabetes and cardiovascular disease. On the other hand, the scientists say that completeness is a healthy way to cope with stress. Doctors say about the "paradox of weight."

Achim Peters, a neuroscientist at the University of Lübeck, and stress researcher Bruce McEwen of Rockefeller University in New York, invited 20 students with normal weight and 20 students are overweight for an interview and a math test.

I lean students significantly increased levels of cortisol in the blood, full of participants did not respond to the stress tests, and their cortisol levels remained the same.

Cortisol is a hormone in the body, relieves stress, and is produced in the body in obesity.

Why do fat people in stressful situations produce less cortisol than lean remains unclear.

"Obesity is not as dangerous as we always thought," — says Ingrid Myulhoyzer, researcher, dealing with the problems of health in the University of Hamburg. The risk of developing diabetes and heart problems should be taken into account, according to Myulhoyzer. But people who are overweight have more reserves and increase in cholesterol — LDL, is responsible for the binding of toxic products in the metabolism may be a protective factor.

Myulhoyzer in 2009 conducted a study that proves that fat people are living longer. And also, in accordance with the study of nephrology United States, noted that in 1999, thin patients suffering from kidney disease, died earlier than patients who are overweight. The same was observed in cases of sepsis, cancer, stroke, and even rheumatism.

Highest longevity research Myulbhoyzer, observed in humans having a body mass index (BMI) 27 (80 kg at a height of 170 centimeters).

BMI is a measure of body weight. This value, which can calculate indicates whether the body weight in the range of gauge, straight or underweight.

Until now, doctors were unanimous: the ideal BMI for men from 20 to 25 and for women from 19 to 24. If the results of the study will take into account the "paradox of weight," the proposed common values become obsolete.
