Why do we gain weight when we get older

Many people have trouble keeping on weight when you are older. Researchers from the Karolinska Institute in Sweden have found out why this is so: The activity in the fat tissue decreases with increasing age and no longer facilitates the weight gain even if you eat and as much sports as before.

The scientists investigated the fat turnover in 54 men and women over an average period of 13 years and found that all participants in the course of time, the speed decreased, with the so-called lipids from the fat cells removed or in them were saved. Who doesn’t compensate for this, less calories, increased according to the study, whose results were published in Nature Medicine, an average of 20 percent.

The researchers also examined the fat metabolism in 41 women in whom the stomach had been reduced in size by surgery. The result showed that only those that had before the surgery, a low-lipid turnover, managed to increase it and maintain your weight loss over several years after the SURGERY. The researchers believe that these women may have had more Potential to increase lipid turnover, than those in which the metabolism was already active.

"The results show for the first Time, that the processes in our fat regulate tissue changes of body weight during aging in a way that ist&quot of other factors, independent;, Peter Arner, Professor at the medical Department in Huddinge at Karolinska Institute said. The new results provide a further indication of the importance of physical activity for the weight. As a way to accelerate the lipid turnover in the adipose tissue, is to move more.
