According to new research in Sweden, people who undergo weight loss surgery not only change their waistline, they also change the genes that regulate fat.
The study compared the genes of obese adults who underwent gastric bypass to those who did not. They found genes involved in glucose and fat metabolism were restored to a healthy state among those who had the surgery.
They say this may contribute to the rapid amount of weight loss experienced by people who undergo surgery.
Researchers hope to use this information to make new drugs to treat obesity.
