We visit IGF-1 and whether there’s a tradeoff between having high or low levels. We discuss the PPARs (receptor proteins) and genetic polymorphisms. Does Rhonda think there’s any benefit in a NAD+ booster for health and longevity? Can saunas lower the risk of heart disease, dementia, and all-cause mortality? We dig into those questions…and a lot more. We discuss: -What Rhonda believes differently today than she did a few years ago; -The paradox of GH/IGF-1 in performance and longevity; -The role of PPAR in fat metabolism and ketogenic diets; -The possible genetic explanations for why some patients don’t respond well to a ketogenic diet; -The health benefits of heat and cold exposure; -NAD+; and -More.
