Guest Bio

Chad Macias


Chad is currently pursuing post-graduate research in Molecular Oncology. He is in the process of writing a review paper on ketogenic diets and cancer, along with Brad Dieter and Tim Sharpe. Chad has spent over 19 years conducting research and developing protocols in cellular and molecular physiology. He is an adjunct faculty member at the University of San Diego, and has developed some of the most advanced blood lactate testing and intermittent hypoxia protocols in the world.

He founded the Institute for Human Kinetics in 2011, where he works with many of the world’s top athletes. In addition, he was a two sport Olympic athlete. He also serves as the Human Performance Specialist at Navy Special Warfare developing programs to prepare Navy Seals for combat deployment though their Tactical Athlete Program. Chad also heads OPI’s Research Team and has the knowledge base to conduct medical and exercise physiology research in both humans and rodents.

In this episode we discuss:

  • How ketones have the potential to accelerate tumour growth in some cancers
  • Why you can’t “starve cancer cells” with a ketogenic diet
  • The complexity of cancer
  • Is cancer a genetic disease, metabolic disease or both?
  • Issues with the way some cancer research is being interpreted and communicated
  • Criticisms of the conclusions being made based on the experimental models used
  • Why recommending cancer patients embark on a ketogenic diet is premature & potentially counter-productive
