Researchers have found that lipid turnover in the fat tissue decreases during ageing and make it easier to gain weight, even if we don't eat more or exercise less than before.
"The results indicate for the first time that processes in our fat tissue regulate changes in body weight during ageing in a way that is independent of other factors," said study author Peter Arner, Professor at Karolinska Institute in sweden.
For the study published in the journal Nature Medicine, the research team examined the fat cells in 54 men and women over an average period of 13 years. In that time, all subjects, regardless of whether they gained or lost weight, showed decrease in lipid turnover in the fat tissue, that is the rate at which lipid in the fat cells is removed and stored.
