A new Swedish study finds that the causes of obesity in aging are not related to the quantity and nature of the food we eat, not only the lack of movement, but there is a decisive factor, which opens the way to address obesity in future.
Recent research at the Karolinska Institute in Sweden has shown that obesity is largely due to decreased fat loss in adipose tissue, which facilitates body weight gain.
The study shows that it is difficult to avoid weight gain in old age even if nothing changes in the actual conditions of life, ie, not eating large amounts of food, or exercise.
Researchers at the Karolinska Institute 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 fats over time, and thus store them, and the study did not focus on the importance of increasing the weight of the subjects tested or reduced over time.
Some of the people tested experienced this physical change and adjusted their eating habits to eat foods with fewer calories, while others did not, gaining an average of 20% more weight than the first group.
According to the study, published in the journal Nature, researchers were able to show that weight gain in aging does not depend on known factors such as poor eating habits or lack of movement and lack of exercise.
"The results show that processes in our adipose tissue regulate changes in our body weight during aging in isolation," explains Peter Arnes, professor of medicine at the Karolinska Institute and lead author of the study. Adding that these results may open the door to completely new ways in the treatment of obesity.
But regardless of the results of this study, physical activity and exercise remain of great importance in the maintenance of body health, it has been shown that exercises help to increase the frequency of fat metabolism stored in adipose tissue.
