Slim Bad? Scientists discover the secret of people who never get fat – News

In a study published in the scientific journal PLOS Genetics, researchers at the British Universities of Cambridge and Bristol state that, for some people, they discovered why some people never put on weight, while others were gaining weight easily. The "secret" of being thin has more to do with the inheritance of a "lucky" gene pool than with maintaining a healthy or healthy diet. a perfectly rigid lifestyle.

To reach these conclusions, the scientists compared DNA samples from 1,600 healthy and thin people – with a body mbad index below 18 – to 2,000 extremely obese people and 10 400 people of normal weight.

In recent decades, the subject has been less explored in research than that of the latter; they also badyzed lifestyle data, for example to exclude eating disorders.

The study reveals the genetic aspects related to slimming recently discovered. on genetic changes that increase the risk of overweight – which has led to hundreds of discoveries in the region.

What does this study show?

Researchers found that obese people were more likely to have a set of genes related to obesity. Meanwhile, lean women had not only fewer genes related to obesity, but also changes in genetic areas recently badociated with healthy leanness.

"This study shows for the first time that lean and healthy people are generally leaner with fewer genes that increase the risk of being overweight and not because they are morally superior, as some say," said the principal investigator of the study Sadaf Farooqi of the University of Cambridge

.

"It's easy to judge and criticize people for their weight, but science shows that things are very difficult."

Farooqi stresses that people should not be so critical of others. we have much less control over our weight than we might think, "he said.

Scientists say the next step is to identify genes eg

Tom Sanders, Professor Emeritus of the American Academy of Nephrology and the American Academy of Endocrinology, Nutrition and Dietetics at King's College London, emphasized the importance of this study. " study confirms that severe early obesity is often determined by genes and convincingly shows that those who are very thin are genetically different from the general population. "

The professor adds that" most of the Obesity is acquired in adult life and is related to the obesogenic environment in which we live – a sedentary lifestyle with a lot of access to high calorie foods. "

Professor Tim Spector, also of King's College London, said that despite this," Part of this is related to genes, but other factors, such as that individual lifestyle differences or intestinal microbes also influence this, "he said.
