you are Probably one of those people who are struggling to keep your weight under control as they age. Now, science has discovered the reason why they get fat with age: the guilt is in the process of replacement of lipids in the adipose tissue -the speed at which it is removed and stored-fat, which decreases during the aging process and facilitates the increase of weight, even if we don't eat more or do less exercise than before . The study is published today in the journal "Nature Medicine".
scientists of Karolinska Institute (Sweden) studied the fat cells of 54 men and women during a period of 13 years . At that time, all subjects, regardless of whether they won or lost the weight, showed decreases in the turnover of lipids in the adipose tissue, which is the speed at which it is removed and stored lipids (or fats) in fat cells.
that was not compensated for this by eating fewer calories, gained weight at an average 20 percent , according to the study that was conducted in collaboration with researchers from the University of Uppsala in Sweden and the University of Lyon in France.
The data indicate, for the first time, that the processes in our fat tissue regulate changes in body weight during aging in a way that is independent of other factors
The researchers also examined the renewal of the lipids in 41 women who underwent bariatric surgery and how the rate of renewal of lipids affected his ability to keep the weight between four to seven years after surgery. The result showed that only those who had a low rate before the surgery were able to increase their volume of lipid, and maintain your weight loss . The researchers believe that these people may have had more space to increase its volume of lipid than those who have already had a previous surgery of a high standard.
"The data indicate, for the first time, that the processes in our fatty tissue regulate changes in body weight during aging in a way that is independent of other factors ", says Peter Arner, one of The main authors of the study. "This could open new ways of treating obesity."

previous Studies have shown that one way to accelerate the turnover of lipids in the adipose tissue do more exercise . This new research supports that notion and indicates in addition that the long-term outcome of weight-loss surgery would improve if it were combined with increased physical activity.
"obesity and obesity-related diseases have become a global problem," says Kirsty Spalding, another of the main authors of the study. "To understand the dynamics of the lipids and thus regulates the size of the fat mass in human has never been more relevant".Updated Date: 12 September 2019, 02:01
