Ketogeek's Podcast

Our Ketogeek podcast is a no holds bar show about health, nutrition, fitness and the low carb lifestyle. In this show we bring in prominent guests in and out of the low carb universe while helping you change yourself and be a beacon of change for others around you!

In this very information-loaded podcast, we talk about many topics pertaining to biochemistry, autophagy, mTOR, Immunometabolism, protein structures, the impact of aging in muscle protein synthesis and the important role of protein in living organisms. 


Lucas Tafur is currently working as a postdoc studying the regulation of TOR complexes in yeast. He is onterested in a wide range of topics related to human health and metabolism, and lately mostly towards skeletal muscle. He is trying to understand physiology using a bottom-up approach, starting from the molecular basis and building up to the organismal level, considering an evolutionary background for interpretation. He currently writes articles in his personal blog and in Nutmol, a spanish website on nutrition and metabolism with a molecular biology-centric perspective (
