Summary
In this episode of the KetoPro Podcast, Richard Smith welcomes back Professor Tim Noakes to discuss the impact of low carbohydrate diets on athletic performance. They explore recent research findings that challenge traditional beliefs about carbohydrates and muscle glycogen, emphasizing the importance of blood glucose levels during endurance activities. The conversation also addresses the adaptation process for athletes transitioning to low carb diets, the health implications of dietary choices for athletes, and the evolving landscape of sports nutrition. In this conversation, the speakers delve into the implications of carbohydrate consumption on athletic performance and overall health. They discuss the hidden dangers of high carbohydrate diets, the efficiency of fat as a fuel source, and the body's macronutrient needs. Personal experiences with zero carb diets are shared, along with insights into the future of research in this area. The conversation also touches on the addiction to carbohydrates among athletes and the genetic factors influencing performance. Ultimately, the speakers advocate for a shift in dietary practices to enhance health and athletic longevity.
Takeaways
- The low carb diet is gaining traction in various sports.
- Carbohydrates can enhance performance, but only during prolonged exercise.
- Muscle glycogen depletion is not as critical as previously thought.
- A small amount of glucose can improve endurance performance.
- Blood glucose levels play a significant role in athletic performance.
- Many studies fail to account for adaptation periods in low carb diets.
- Elite athletes may not always be the best model for dietary studies.
- Health concerns are rising among athletes consuming high carb diets.
- The shift towards low carb diets in sports is inevitable.
- Individual performance improvements matter more than comparisons with elite athletes. High carbohydrate diets can lead to insulin resistance.
- Fat can provide the majority of energy needed for endurance sports.
- The human body is capable of burning fat efficiently.
- Glucose is essential for brain function during exercise.
- Zero carb diets can lead to improved athletic performance.
- Athletes often consume excessive carbohydrates unnecessarily.
- Genetics play a significant role in athletic performance.
- Addiction to sugars is prevalent among athletes.
- Long-term health benefits from a low-carb lifestyle are significant.
- Research on zero carb athletes is needed to understand their performance.

In this episode of the KetoPro Podcast, Richard Smith talks with Professor Tim Noakes about the role of low-carb diets in sports. They discuss Noakes' latest research, which offers insights into how carbohydrates influence athletic performance, particularly in endurance sports. The conversation highlights how the average athlete may not require excessive carbohydrates, and successful performance can be achieved on low-carb or fat-adapted diets.
Key Points
Carbohydrates and Athletic Performance
Professor Noakes discusses whether carbohydrates are necessary for enhancing athletic performance. His research indicates that carbs do boost performance but primarily during prolonged exercise when blood glucose levels drop.
Low-Carb Diets in Sports
Noakes mentions that one of the top coaches in a sport believes low-carb diets will become standard, reflecting a growing acceptance of such diets among athletes.
Research Findings on Fat Utilization
The research conducted by Noakes and his team shows that high-fat diets do not compromise endurance performance. In various trials, athletes maintained their performance levels on low-carb diets, emphasizing fat as a preferred fuel source.
Glucose's Role During Exercise
The discussion reveals that only small amounts of glucose are needed during prolonged exercise to prevent hypoglycemia rather than to fuel muscle metabolism.
Impact of Diet on Health and Performance
The episode underscores the relationship between diet and health, with low-carb diets shown to improve blood glucose control and overall health metrics, potentially extending athletes' careers.
Cultural and Psychological Barriers to Diet Change
Noakes and Smith talk about the addiction to carbohydrates in both amateur and elite athletes, explaining how societal norms influence dietary habits.
Future of Nutritional Practices in Sports
Professor Noakes predicts a shift towards carnivore and low-carb diets in professional sports as more evidence emerges in support of these diets.
