For many years, people have been told that the best way to stay healthy is to exercise regularly and avoid eating too much fat.
Exercise is known to strengthen the heart, help control weight, and improve how the body uses oxygen to produce energy. This ability to use oxygen efficiently is closely linked to better health and a longer life.
However, not everyone gains the same benefits from exercise. People with high blood sugar, also known as hyperglycemia, often struggle to improve their fitness even when they exercise regularly.
Their muscles do not respond as well, and their bodies may not use oxygen as effectively. This puts them at higher risk for serious health problems such as heart disease and kidney damage.
A new study published in Nature Communications offers an unexpected idea. Instead of reducing fat, increasing fat intake through a ketogenic diet may help improve both blood sugar levels and the body’s response to exercise.
The research was led by Sarah Lessard, an exercise scientist at the Fralin Biomedical Research Institute at Virginia Tech. Her team studied mice with high blood sugar and placed them on a ketogenic diet. This type of diet is very low in carbohydrates and high in fat, which pushes the body to use fat instead of sugar for energy.
The results were striking. After just one week on the diet, the mice’s blood sugar levels returned to normal, almost as if they did not have diabetes. Over time, their muscles also changed in important ways. The muscles became better at using oxygen, which is a key sign of improved fitness.
The researchers found that the mice developed more slow-twitch muscle fibers. These fibers are important for endurance and long-lasting activity, such as walking or running. They allow the body to use oxygen more efficiently and support better performance during exercise.
This finding is important because it suggests that diet can directly influence how the body responds to exercise. In people with high blood sugar, the usual benefits of exercise may be limited. But changing the diet could help unlock those benefits.
The ketogenic diet has been studied for many years. It was first used in the early 20th century to treat epilepsy and was also used before insulin was discovered to manage diabetes. Today, it remains a popular but sometimes controversial diet because it involves eating a high amount of fat and very few carbohydrates.
While the results of this study are promising, it is important to remember that the research was done in mice, not humans. Human bodies are more complex, and the same effects may not occur in the same way. More research is needed to confirm whether these findings apply to people.
Another important point is that the ketogenic diet can be difficult to follow. It requires strict limits on carbohydrates, which can make it challenging for many people to maintain over time. Because of this, researchers suggest that other diets, such as the Mediterranean diet, may offer similar benefits while being easier to follow.
The study also highlights that diet and exercise do not work separately. They interact with each other in important ways. Simply exercising without addressing diet may not be enough, especially for people with high blood sugar.
In conclusion, this study suggests that a high-fat diet may help improve how the body responds to exercise in people with high blood sugar. However, more research in humans is needed, and individuals should always consult a doctor before making major changes to their diet.
