In this episode of the Heal, Nourish, Grow podcast, host Cheryl McColgan interviews Dr. Chris Rhodes, a nutrition scientist and co‑founder of Mimio Health. Dr. Rhodes shares his journey from biochemistry studies to a focus on longevity and fasting, explaining how fasting activates cellular cleanup (autophagy) and metabolic pathways (mTOR, AMPK, NAD+/SIRT) that can extend healthspan. He discusses the recent surge in interest around GLP‑1 drugs such as Ozempic and how they intersect with longevity pathways. The conversation moves to his personal fasting experiments, the social challenges of long fasts, and the motivation to create a fasting‑mimetic supplement. Dr. Rhodes describes the discovery process: metabolomic profiling of 36‑hour fasts identified over 300 altered metabolites, from which a synergistic quartet—nicotinamide, spermidine, palmitoyl‑ethanolamide (PEA), and oleoyl‑ethanolamide (OEA)—was selected. Pre‑clinical work showed a 96 % lifespan extension in C. elegans, outperforming metformin and rapamycin. Human pilot studies demonstrated that a single dose of Mimio prevented post‑prandial loss of plasma function and, in an 8‑week Mount Sinai trial, improved glucose, lipid markers, and reduced biological age by 2.5 years. The host raises concerns about muscle loss and mTOR signaling; Dr. Rhodes explains that Mimio balances mTOR/AMPK without hindering muscle growth, citing anecdotal performance gains from users. The episode also includes promotional segments for a neurofeedback sleep mask and a dry‑farm wine brand, and concludes with directions for listeners to follow Dr. Rhodes on TikTok and learn more via the Mimio website.
