Beijing time on May 25, according tomedia reports, when you are still worried about weight loss is, there is such a category of people may make you envious of jealous to die, the study found that only 1% of people can “do what they want”, eat what they want, and weight will not increase, because the population has a “slimgene gene.”
Scientists analyzed the genetic profiles of thousands of testers and found that about 1 percent lacked a gene called ALK. The results show that these healthy adults are naturally thinner than other healthy adults, and scientists speculate that the ALK gene may be related to their lean body size.
They then tested mice and flies in the hope of validating the hypothesis, and the results showed that “turning off” the ALK gene would keep mice and flies lean, even if they ate foods rich in sugar and fat. So turning off the ALK gene could become the basic therapy for human obesity in the future.
People who turn off the ALK gene in the body do not have to control their appetite to maintain a good metabolism, they can usually eat a large amount of food, in the normal digestive metabolism on the basis of the weight will not increase. For years, scientists have been interested in the ALK gene, which is now being treated with drugs that have been rapidly altered by mutations in some cancers, which are known as “carcinogenic genes”, thus accelerating the development of cancer treatment.
So far, the role of the ALK gene in other parts of cancer is unclear, but the latest findings suggest that it is crucial to thinning, and that scientists need to do more research to determine the true effectiveness of the program before drug inhibitors can act on the body.
The next stage will be to compare the findings with the health, activity levels and DNA “biobank” records of residents in other countries, and this latest discovery will help combine the exploration of the genetic basis of human thinning with genome-wide analysis of living organisms (rats and flies).
The different research teams work together in a variety of fields, from nutrition to biological databases to genetic genetics of mice and flies, including the evolution of biological metabolism, the evolutionary role of the ALK gene, multiple experimental evidence synods in humans, and the provision of causal evidence of core biochemistry and genetics. The latest study is now published in the recent issue of the journal Cell.
What are the criteria for obesity? What health risks does it pose?
Body type obesity refers to an adult with a body mass index (BMI) of 30 or above, typically between 18.5 and 24.9 in a healthy person.
The most immediate effects of obesity are physical health, which can even be life-threatening, leading to type 2 diabetes, kidney disease, blindness and amputation. Obesity also increases the risk of heart disease, making it the leading cause of death. Dangerous signs of obesity have also been linked to 12 different types of cancer, including breast cancer, with an average of 12.5 percent of obese women having breast health problems.
In addition, obesity can lead to high blood pressure or high cholesterol, increase the risk of heart disease, obese children are more likely to become obese adults in adulthood, if they are overweight in childhood, then they are more likely to become obese in adulthood. (Ye Ding Cheng)
