Chris Irvin, M.S. - Peak Human Podcast


Listen on


This is an interesting episode that features Chris Irvin, M.S. who actually interviewed me on his podcast: Keto Answers. Chris is a health researcher, writer, and educator focusing on the impact of low carb and keto diets on health and human performance.

Chris has a master’s degree in exercise and nutrition science and spent his time in graduate school studying and conducting ketogenic research. Chris is the creator of the brand The Ketologist, which is known for producing social media infographics and educational health content. He is the author of Keto Answers, Mommy Do I Have to Eat This?, and is the education manager at Perfect Keto.

In the episode, we discuss what happened over a 40-year period that changed our food industry to this day, the problem with nutrition epidemiological studies, why a plant-based diet bias exists and how that’s negatively affecting us, why counting calories is ineffective and what to focus on instead, satiety signals, and so much more. You’ll also hear more about my story, Food Lies and how this differs from other nutritional documentaries out there.

We have products such as primal ground beef that includes liver, heart, kidney, and spleen for all the amazing nutrients and none of the hassle or taste you may not be used to.
