Ep. 10 - BMI: Misunderstood, Misused, and Still Useful?

In this episode of Metabolic Mastery from KORR Medical Technologies, Dr. Marc Humbert and Dr. Cameron Garber dig deep into BMI—Body Mass Index. Often misunderstood and misapplied, BMI remains a widely used health metric. But does it still deserve a place in modern fitness and medicine? The doctors unpack the science behind BMI, its historical roots, and its usefulness (or lack thereof) when applied to individuals. They explore the J-shaped mortality curve, risk stratification, the limits of BMI in assessing fitness and fatness, and better alternatives like VO₂ max testing and body composition analysis. Whether you're an athlete, clinician, or simply health-conscious, this episode offers practical insights into how to better understand your health metrics and build a sustainable approach to longevity and performance. 💪 Topics include: Why BMI fails to measure fitness and fatness The true "sweet spot" for longevity Fat but fit vs. skinny fat: What's riskier? Muscle quality, metabolic flexibility, and sustainable training VO₂ max testing and how it helps optimize your healthspan Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery  Show Notes: Mortality BMI Mortality Risks & Confounders - https://pubmed.ncbi.nlm.nih.gov/27146380/ BMI (J-shaped curve) and Mortality - https://pubmed.ncbi.nlm.nih.gov/30389323/ VO2max and Mortality - https://pubmed.ncbi.nlm.nih.gov/39537313/ AAS use and Mortality - https://jamanetwork.com/journals/jama/fullarticle/2816584 Low lean body mass and Mortality - https://pubmed.ncbi.nlm.nih.gov/29970408/ https://pubmed.ncbi.nlm.nih.gov/32518354/ Deep belly fat and Mortality - https://pubmed.ncbi.nlm.nih.gov/28671751/ Waist to Height and Mortality - https://pubmed.ncbi.nlm.nih.gov/37770574/ Aerobic & Resistance Training and Mortality - https://journals.lww.com/acsm-healthfitness/fulltext/2023/11000/the_coming_of_age_of_resistance_exercise_as_a.7.aspx "Fat but fit" implications https://pubmed.ncbi.nlm.nih.gov/39537313/ https://pubmed.ncbi.nlm.nih.gov/27230640/ https://pubmed.ncbi.nlm.nih.gov/29064474/ https://pubmed.ncbi.nlm.nih.gov/24400816/ https://pubmed.ncbi.nlm.nih.gov/33580798/ Muscle Quality & Impacts Loss of physical function with aging - https://iris.who.int/handle/10665/66682 Fall risk in elderly - https://pubmed.ncbi.nlm.nih.gov/31095087/ Influence of adiposity on muscle tissue - https://pubmed.ncbi.nlm.nih.gov/23790255/ Importance of muscle quality - https://pubmed.ncbi.nlm.nih.gov/25520782/ Effects of fat infiltration on muscle – https://pubmed.ncbi.nlm.nih.gov/35980018/ https://pubmed.ncbi.nlm.nih.gov/30620635/ https://pmc.ncbi.nlm.nih.gov/articles/PMC3910392/ https://pubmed.ncbi.nlm.nih.gov/23147096/ Resistance Training & Muscle Health https://pubmed.ncbi.nlm.nih.gov/37881849/ https://pubmed.ncbi.nlm.nih.gov/38123165/ Metabolic flexibility - https://pubmed.ncbi.nlm.nih.gov/35287953/
