Episode 2315 – On this Friday’s show Vinnie Tortorich and return guest Professor Tim Noakes discuss sports science, dealing with carb intolerance, your brain and “the bonk”, and much more.
DEALING WITH CARB INTOLERANCE
- Vinnie and Prof. Tim Noakes begin with a discussion of Tim’s professional background, especially in the early years of sports science. (2:00)
- He has been involved with sports science for decades.
- Sports science studies the whole human biological system, and its entire functioning.
- They discuss the early days of sports science used in the Olympics and other events like the Tour de France and what things were discovered.
- Tim has written several books such as Lore of Running (now in its 4th edition) and Real Food on Trial. (11:00)
- Tim constantly reviews new information and updates his work based on the findings; you have to move with the evidence.
- Vinnie asks Tim to share what the issue was with Tim’s historical trial and the “tweet heard around the world”. (17:30)
- The trial was about information and not being able to speak outside the narrative of certain organizations.
- He gives various details about the trial, too.
- They turn to the topic of Diabetes. (26:00)
- Tim shares his history dealing with T2D and what he’s discovered about himself using a low-carb lifestyle.
- He emphasizes that diabetes is carb intolerance.
- Vinnie and Tim discuss dealing with carb intolerance and give examples of ideal levels. (33:00)
- Even 1 gram of higher insulin inhibits the burning of fat.
- Many people don’t understand that if they have large amounts of visceral fat, they are insulin resistant and at the very least, pre-diabetic.
- Your liver can produce any glucose your brain needs, except possibly over 4-5 hours of constant exercise; Tim explains. (35:00)
- The purpose of “carb burning” is not because your body “needs” the carbs; it’s because your body is trying to burn off (or get rid of) the glucose in the blood. (35:20)
- Keeping your glucose and insulin flat is what keeps you healthy. (37:00)

THE “BONK”
- They also discuss going through a “bonk”, and how the brain responds to carbs, even sweetness. (37:15)
- Tim discusses a study where they discovered surprising results about burning carbs vs. burning fat.
- The people in the study who were pre-diabetic benefitted the most from a high-fat diet. (50:30)
- This leads to a discussion about questioning long-held theories. (51:00)
- So they discuss the different Zones in exercise that can be done on a ketogenic diet–it’s higher than previously thought!
- They chat a bit about the training and success of Kenyan and Ethiopian elite runners. (55:00)
- Vinnie gets Tim’s take on the use of drugs like Ozempic. (58:00)
- Changing your behavior is the only real way to be successful with your health.
- You can donate to the Noakes Foundation or The Nutrition Network; Tim explains the important work that they do.
