How to Personalize your Health Using Genetics with Justin Harris

Genetics provide the context most training and nutrition plans are missing.In this episode, I sit down with Justin Harris to explain why starting with genetics removes so much of the guesswork. The body has a built-in hardware that shapes how your body responds to food, training, stress, and supplements long before habits come into play. Once you understand that framework, your decisions stop feeling random.We walk through real examples, including why some people struggle with caffeine, vitamin D, high-fat diets, or recovery even when they are doing the right things. These patterns are not random, and they are rarely about effort.We also cover when genetic testing actually makes sense and why it works best once the basics are already in place. If you want fewer guesses and better decisions around training, nutrition, and long-term health, this episode is for you.
