Many people struggle to keep the weight off as they get older even if they workout regularly. Now a new study reveals why people gain weight as you age. According to the study, it becomes easier to gain weight because the fat tissue decreases during the ageing process.
The study, conducted by a team from the Karolinska Institutet in Sweden,investigated the fat cells of 54 participants for almost 13 years. A reduction in lipid turnover in the fat tissue occurred regardless of whether the participants gained weight or lost weight. The study's findings were originally published in the journal Nature Medicine.
"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," study author Peter Arner, a professor at the Department of Medicine in Huddinge at Karolinska Institutet, told a news portal. Adding, "This could open up new ways to treat obesity."
Previous research indicated you could speed up the lipid turnover in the fat tissue by working out more. "Obesity and obesity-related diseases have become a global problem," Kirsty Spalding, a senior researcher at the Department of Cell and Molecular Biology at Karolinska Institutet, told a news portal. Adding, "Understanding lipid dynamics and what regulates the size of the fat mass in humans has never been more relevant."
Another study claims coffee could help tackle obesity.Researchers say a cup of coffee can stimulate 'brown fat', which is the body's defence against fat. "Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold. Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss. However, until now, no one has found an acceptable way to stimulate its activity in humans," study author Michael Symonds, a professor at the University of Nottingham, told a news portal.
Symonds further explained: "The results were positive and we now need to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there's another component helping with the activation of brown fat. We are currently looking at caffeine supplements to test whether the effect is similar."
