Exercise Changes the Way Our Bodies Handle Saturated Fat, a Study Shows

Scientists in the UK appear to have discovered another benefit of exercise: it could make our bodies better at using certain types of fat. In a new study published this week, researchers found that endurance athletes were much better at burning saturated fat compared to sedentary people with type 2 diabetes – a difference that was also evident in the diabetic group when they also started started training.

The research was led by scientists from the University of Aberdeen. They were interested in solving a particular biological puzzle known as Athlete paradox. Studies have found that both endurance athletes and type 2 diabetics tend to store larger amounts of fat in their muscle fiber cells compared to others, although they are otherwise very different. Athletes typically have a much lower risk of cardiovascular disease than, for example, diabetics and usually have high insulin sensitivity (by definition, people with type 2 cannot respond to or produce insulin effectively).

To better understand the origins of this phenomenon, researchers recruited 29 male endurance athletes and 30 patients with diabetes for an experiment.

First, the volunteers were injected intravenously with small amounts of different fats and had their thighs scanned using MRI to see how these fats were used by muscle cells. In addition, the cells of the thigh muscles were biopsied and basic metabolic measurements were carried out. Then, for the next eight weeks, the volunteers essentially swapped lives: the exercisers forgo their usual physical activity and the type 2 diabetics completed endurance training, to the point that they were exercising five hours a week. After the eight weeks, the same tests were carried out again.

The researchers found that the athletes’ bodies stored more saturated fats in their muscle cells than the diabetics’ bodies, but also burned them very efficiently. In contrast, the diabetics’ bodies stored more unsaturated fat in their muscles but were worse at burning both types of fat. However, after the swap, the two groups began to mirror each other, with the exercising diabetics now storing and burning about as much saturated fat as the deconditioned athletes.

The team’s findings, published Wednesday in Nature Communications are based on a relatively small sample size. Therefore, further studies are needed to confirm what the team found here. However, numerous studies have shown that exercise can improve our health in many ways. Therefore, it is quite possible that this is just one of them.

“These results are completely new and highlight how the metabolism of saturated fat improves with exercise when you stay fit and active,” said lead study author Dana Dawson, chair of cardiovascular medicine at Aberdeen, in a statement opinion from the university.

Aside from burning fat better, the researchers also found that the people with diabetes lost weight, increased their insulin sensitivity, and lowered their cholesterol, triglycerides, and fasting glucose levels once they started exercising – all good reasons for anyone who doesn’t Training started.

“When it comes to being active, it’s important to develop a routine that you enjoy and can stick to,” Bryan Williams, scientific and medical director of the British Heart Foundation, said in a university statement . “Try to build up to 150 minutes of moderately intense activity per week, such as a brisk walk, swimming or cycling.”
