The Impact of Exercise on Cholesterol: HDL, LDL, and Triglycerides

As a 66-year-old health and fitness enthusiast, I have long been fascinated by the intricate relationship between physical activity and cholesterol levels. For decades, I have kept a close eye on my cholesterol profile, which includes total cholesterol, LDL, HDL, and triglycerides, and I have observed its subtle changes.

The Inconspicuous Effects of Exercise on Cholesterol

Despite engaging in various forms of exercise, including high-intensity and longer durations, the impact on my total cholesterol, LDL, and triglyceride levels remains relatively unnoticeable when viewed through the lens of my monthly lipid profile tests. However, there is one notable exception: HDL levels do exhibit a trend of improvement with increasing physical activity.

While my exercises do contribute to a modest increase in HDL, I have found that their impact on HDL is not as dramatic as their effect on blood sugar levels. In fact, my workouts have led to a very significant reduction in my blood sugar, even though they do not bring my LDL cholesterol levels into the normal range. This suggests that the benefits of exercise on blood sugar management are more pronounced than on cholesterol levels.

Struggling with Managed Cholesterol and Diabetes

It must be noted that my diet is also meticulously managed, and it has been remarkably effective in controlling my diabetes without the need for medication. However, the effects of both diet and exercise on my cholesterol levels have been relatively modest. Dietary modifications and regular exercise have not been sufficient to bring my LDL cholesterol within the desirable range.

Seeking Scientific Guidance and Confidence

Given the significant changes in my blood sugar and the phenomenon of my HDL levels responding positively to exercise, I have decided to follow the advice of Dr. Robert Lustig, a Professor Emeritus of Pediatrics, and my own personal guidance. Dr. Lustig has significantly influenced my understanding of cholesterol and the role of exercise.

Dr. Lustig emphasizes that diet and lifestyle interventions, such as exercise, can play a crucial role in managing cholesterol levels. He believes that the conventional approach, which often involves medication, may not always be the best solution for everyone. His approach aligns with my own experiences and observations, leading me to feel more confident in not relying on cholesterol medications prescribed by my family doctors.

However, it is important to note that Dr. Lustig's approach is not universally accepted. Many medical professionals would still recommend that cholesterol levels, especially those of LDL, are kept within the normal range through medication. This highlights the importance of consulting with qualified healthcare providers and considering individual circumstances and preferences.

Conclusion

In conclusion, while exercise and diet have played a role in managing my diabetes without medication, the impact on my cholesterol levels, particularly LDL, has been limited. HDL levels, on the other hand, have shown a positive response to exercise, even if not as dramatically as expected.

The advice of Dr. Robert Lustig, along with my own observations and experiences, have given me the confidence to follow a more natural and lifestyle-focused approach to managing my cholesterol. However, it is crucial for anyone making such decisions to consult with healthcare professionals to ensure a well-rounded and informed approach to their health.
