Scientists have found out why people get fat with age

Experts from the Karolinska Institute and Uppsala University in Sweden, together with colleagues from the University of Lyon in France, found one of the reasons why people gain weight as they age, even if they continue to exercise and eat no more than usual. According to the new study printed in the Nature Medicine journal, this is due to disorders of lipid metabolism in the body.

Researchers observed a group of 54 people for 13 years and monitored changes in their adipose tissue. Over this period of time, the weight of the participants either increased or decreased, or remained unchanged, but all had one similarity — over the years, the level of lipid metabolism in adipose tissues of the participants were decreasing. It was impossible to regulate the rate of absorption of lipids, which led to a gradual weight gain. Subjects who did not start consuming fewer calories to compensate this process gained 20% of weight.

The results indicated for the first time that weight gain occurs with age regardless of other factors. The study opens up new possibilities for the treatment of obesity and other metabolic disorders.
