Insulin resistance is a condition in which cells in the body begin to „ignore“ the action of insulin, the hormone responsible for regulating blood sugar. As a result, blood glucose levels rise, and over time the risk of developing type 2 diabetes increases. The good news is that one of the most effective ways to affect this condition requires no medication - regular physical activity plays a key role.
When we move, our muscles start actively using glucose as an energy source. Interestingly, during physical activity, glucose can enter muscle cells through mechanisms that do not depend entirely on insulin. Furthermore, with regular exercise, cells become more sensitive to it. This means that the body copes more effectively with smaller amounts of insulin.
Fat accumulated in the abdominal area (so-called visceral fat) is closely associated with an increased risk of insulin resistance. Exercise helps reduce this fat and improves overall body composition. Even when the scale doesn't show much change, regular physical activity can lead to a noticeable improvement in metabolic indicators, including better blood sugar control.
Not all exercise works in the same way, but the good news is that different types of activity complement each other.
Aerobic exercise such as brisk walking, running or cycling supports glucose utilisation and improves cardiovascular health.
Strength training, in turn, increases muscle mass. And the more muscles we have, the better our body regulates glucose levels, because muscles are one of the main glucose consumers.
The key to the effects of physical activity is consistency. The best results are seen when movement is part of the daily routine, even moderate activity on most days of the week makes a difference.
On the other hand, prolonged sedentariness itself has a negative effect on metabolism. Even short breaks to move around during the day can help better control blood sugar.
While physical activity is a key factor, it is most effective as part of a broader approach. A balanced diet, maintaining a healthy weight and getting enough sleep are also essential.
Regular exercise is one of the surest ways to improve insulin sensitivity and overall metabolic health. By aiding glucose uptake, improving body composition and reducing the negative effects of a sedentary lifestyle, physical activity plays an important role in both the prevention and control of insulin resistance.
