Greg Dennis: An epiphany over how to achieve optimum health

What happens when a devoted meat-eater spends an hour in conversation with a fellow podcaster, who lives by a plant-based diet?  In this episode of the LLAMA podcast, I meet Dr. Greg Dennis, a family practice physician from Oklahoma City, who also podcasts about health and fitness.  We quiz each other about our longevity-focussed lifestyles – highlighting the significant differences and similarities in our regimes.   Dr. Dennis explains the action he took when he realized that his patients were not getting any healthier, under the traditional “standard of care,” and how it led to his weekly podcast, Fit Rx.  We also share our longevity goals and discuss the challenges posed by conflicting advice on how to live a healthy life.
