Many of us are living an active life but still seeing our waist line expanding. Conventional teaching says we should be losing or maintaining our weight based on our lifestyle however we are still gaining weight. Apparently there is a scientific reason for this. Read on to find out more . . .
The Midlife Weight-Gain Struggle Is Real. Here’s What You Can Do About It
Midlife weight gain is an undeniable phenomenon. But for decades, it’s been blamed on the same old saws: slowing down with age and eating too much.
But as active folks, we know something more had to be going on there: You can ride, race, and train just as much, eat just the same, and still find your kits getting increasingly snug.
Now, science has got your back: There’s a switch that turns on in your fat cells as you get older, making it easier to gain weight even if you don’t eat more or exercise less than before, according to new research published in Nature Medicine.
Specifically, the scientists at Uppsala University in Sweden and University of Lyon in France found that lipid turnover—the capacity to store and remove lipids (a.k.a. fat)—changes for the worse with age. Our lipid removal rates decrease, while our storage rates remain the same. The result, we slowly pack on excess weight.
The study, which was conducted at Karolinska Institutet in Sweden, examined the fat cells of 54 men and women aged 23 to 62 with an average age of 38, over an average period of 13 years.
During that time, the researchers saw a decrease in lipid turnover among all of the men and women. Participants who didn’t reduce their calorie intake during the period saw a substantial weight gain, increasing their body weight by an average of 20 percent—enough to add 30 pounds to a 150-pound frame.
“The results indicate for the first time that processes in our fat tissue regulate changes in body weight during aging in a way that is independent of other factors,” said Peter Arner, M.D., Ph.D., professor at Karolinska Institutet and one of the study’s main authors in a press release.
The good news is, though you can’t stop this process, you can bump up your daily fat burn to help counteract this natural decline.
All exercise helps, of course, but a little hammering turns up the burn best. A recent study published in Medicine & Science in Sports & Exercise found that high intensity interval training (HIIT) was superior to moderate exercise for increasing midlife fat burn.
Specifically, postmenopausal women who performed 20-minute cycling sessions that included high intensity interval training (HIIT) on stationary bikes three times a week for 12 weeks improved fat burning and decreased levels of health-damaging abdominal fat better than their peers who performed 40 minutes of moderate cycling during the same period.
For even better results, add resistance training to the mix. The women in the study who performed resistance training and HIIT lost about three more pounds than those doing moderate cycling or HIIT training alone during the study. Previous research also finds that resistance training can boost your growth hormone levels, which in turn improves fat burning.
Finally, if creeping weight gain is a concern, keep tabs on your food intake. The Karolinska Institutet research team found that, though lipid turnover declined among all the study volunteers, not everyone gained weight. Those who didn’t simply compensated by eating less.

P.S. By combining a healthy diet that includes lots of veggies and high fiber, low glycemic fruits with a consistent exercise routine three to four days each week, even as we age, we can maintain a healthy weight. We will also strengthen our bones, improve our respiration and maintain a more youthful appearance.
