Scientists have discovered the secret that some people keep their slimming while others are overweight. The study of scientists has shown that permanent thinness is linked to genetic factors.
This discovery reinforces the idea that the leanness of some people is not related to their diet or lifestyle, but to the genes in which they were born, according to the multinational team of scientists.
In recent decades, many studies and researches have shown the relationship between certain genes and weight gain, but they have not studied the genes that help maintain thinness.
In this study, the researchers compared DNA samples from about 1,600 healthy people in Britain with samples from about 2,000 people suffering from obesity and diabetes. 39, about 10,400 people of normal weight.
The researchers used lifestyle questionnaires to exclude people with eating disorders, for example. The researchers found that people with obesity increased the probability of presence of genes related to weight gain.
Humans, the genes associated with weight gain, were less likely to have a gene recently linked to thinness.
Sadaf Farouqi, head of the research team and professor at the University of Cambridge, has called on people not to make judgments about the weight of others.
"This study showed for the first time that a healthy hyperventilation is usually benign because they have fewer genes that increase the likelihood of gaining weight, not because they are better than others." as some people think, "she said. "It's easy to judge people and criticize their weight, but science shows that things are more complex, the power of human weight is lower than we think."
Scientists say the next step in the research is to identify these genes responsible for thinness. The long-term goal is to examine whether this discovery will enable new methods of weight loss.
"This study is important, well conducted and confirms that obesity is often determined by genes and shows that thin people are genetically different," said Tom Sanders, a nutritionist at Kings College London. . "Most cases of obesity are found in adult life and are related to the environment that promotes obesity," he said, in terms of fashion less active living and availability of high calorie foods.
Tim Spector, a professor at King's College London, said that about one-third of the population in most countries had managed to stay slim despite this environment. "This is partly due to genes, but other factors, such as individual lifestyle differences or intestinal microbes, are likely to play a role."
Health experts say that, regardless of body or body shape, the old advice is to exercise and follow a good diet.
