News C is why we gain weight easily with age!

A new Swedish study reveals that the causes of age-related obesity are not only related to the quantity and nature of the food we eat, nor to the lack of movement, but that there is a decisive factor that opens the door to way to the treatment of obesity in the future.

In Germany, health has experienced a disturbing trend in recent years: 56.3% of women and 74.2% of men are overweight at the end of their careers. Professor Helmut Hessker, former president of the German Dietetic Association, explains that the causes of weight gain have been known for a long time. "Many people in Germany eat more than what the body needs high energy foods and do not move enough," added the German expert, stressing that it was urgent to take steps measures to limit this.

Recent research conducted at the Karolinska Institute in Sweden has shown that there is another reason for weight gain among older people. The study reveals that obesity is usually due to a decrease in fat loss in adipose tissue, which facilitates weight gain. The study shows that it is difficult to avoid weight gain in the elderly, even if nothing changes in the real conditions of their lives, namely not to eat large amounts of food or exercise.

Researchers from the Karolinska Institute have monitored the fat cells of 54 women and men for 13 years to find a reduction in fat loss in all subjects. This means that fat cells begin to lose their ability to get rid of fat over time and store it. The study did not focus on the importance of increasing or decreasing the subjects' weight over time.

Some of the people tested have faced physical changes and have adjusted their eating habits to eat foods containing fewer calories, while others have not done so, earning an average of 20% weight gain. more compared to the first group.

Fat metabolism was studied in 41 women who underwent gastric bypass before participating in the study, to determine whether women would be able to maintain their minimum weight four to seven years after surgery. The researchers found that only some of them had managed to maintain their weight.

According to Peter Arnes, professor of medicine at the Karolinska Institute and lead author of the study, these women were able to maintain their weight because their rate of fat loss had a higher growth potential and could therefore continue to evolve with the time. Women who have suffered from the beginning have greater fat loss and therefore can not increase it, which is reflected in their eventual weight gain.

According to the study published in the journal Nature, researchers have been able to show that weight gain related to aging does not depend on known factors such as poor eating habits, lack of movement and lack of physical activity. "The results show that the processes of our adipose tissue regulate changes in our body weight during an isolated aging," said Professor Arnis, adding that these findings could pave the way for new methods of treating body fat. l & # 39; obesity.

However, whatever the results of this study, physical activity and exercise remain of great importance for the maintenance of body health. Exercises have been shown to help increase the metabolic rate of fat stored in adipose tissue.
