Wy Does Weight Loss Harder With Age?



If you're in your thirties or forties, you may have noticed that keeping your weight is a bit harder than it was in your twenties. In fact, you may feel like you could indulge in all the beer pizza your heart desires, without any consequences for college, but now your pants are a little tighter after just one extra scoop of peanut butter. Ugh right?

If you can relate to that, you should know two things. First, you are not crazy and second, you are not alone. According to science it is harder to maintain our weight as we age. The good news is that researchers have just found out one of the main reasons.

The study published in Nature Medicine was a collaboration between researchers from Uppsala University in Sweden and Lyon University in France. The team studied the fat cells of 54 men and women for an average of 1

3 years and found that all participants had a decrease in lipid turnover (AKA, how fast fat was either stored or removed from the fat cells). Even more interesting was the fact that this decline in lipid turnover was independent of how much weight the participant has gained or decreased in 13 years.

What does that mean? According to Peter Arner, one of the lead authors of the study and professor at the medical school in Huddinge at Karolinska Institutet, "the results show for the first time that processes in our adipose tissue regulate body weight changes during aging in a manner independent of other factors." In other words, even if neither diet nor lifestyle changes, it will be harder to maintain your weight as you get older.

This is not good news, but according to Arner it's not all bad news since this newly discovered knowledge could open up new ways to treat obesity. As Kirsty Spalding – a senior researcher at Karolinska Institutet and one of the other main authors of the study – explained: "Obesity and diseases related to obesity have become a global problem … understanding of lipid dynamics and regulating the size of fat mass In humans, it has never been so relevant. "

Meanwhile, the authors suggested that previous research indicates that you may be able to accelerate fat metabolism in fat tissues by exercising more.
