The Randle Cycle: How Your Body Chooses Between Glucose and Fat

In this episode of The Metabolic Classroom, Dr. Bikman introduces the concept of the Randle Cycle, also known as the glucose fatty acid cycle, in a lecture aimed at providing a better understanding of metabolism. The Randle Cycle, first identified by Dr. Philip Randle and his colleagues in the 1960s, explores how cells decide between using glucose or fatty acids for fuel. Dr. Bikman emphasized that this cycle has been misinterpreted on social media and aims to clarify its relevance in metabolic functions and nutritional decisions.https://www.insuliniq.com 00:00 - Introduction to the Metabolic Classroom and Dr. Ben Bikman01:00 - Overview of the Randle Cycle (Glucose Fatty Acid Cycle)02:00 - Historical Background: Philip Randle’s Research03:00 - Experimental Model: Perfused Rat Hearts04:00 - Key Terms: Glucose and Fatty Acids05:00 - Concept of Substrate Competition06:00 - Reciprocal Inhibition: Fats vs. Glucose08:00 - Fatty Acid Oxidation Process10:00 - Biochemical Pathways: Acetyl-CoA, NADH, and Pyruvate Dehydrogenase12:00 - Role of Citrate in Glycolysis Inhibition14:00 - Glucose Utilization and Malonyl-CoA16:00 - Insulin’s Role in Fuel Selection18:00 - Insulin’s Impact on Glucose and Fat Burning20:00 - Diabetes Case Study: Type 1 and Type 222:00 - Type 1 Diabetes: High Glucose and Fatty Acids24:00 - Ketones Production in the Liver26:00 - Type 2 Diabetes: Insulin Resistance and Metabolic Inflexibility28:00 - Insulin Resistance in Fat Cells30:00 - Metabolic Inflexibility in Type 2 Diabetes32:00 - Insulin Resistance in the Brain34:00 - The Impact on Hunger and Neurological Disorders36:00 - Conclusion: Importance of Insulin in Metabolic Health#Metabolism #RandleCycle #DrBenBikman #InsulinResistance #GlucoseMetabolism #FattyAcidOxidation #MetabolicHealth #DiabetesResearch #Ketosis #Type1Diabetes #Type2Diabetes #InsulinRole #CellBiology #NutritionalScience #MetabolicFlexibility #Ketones #GlucoseUtilization #FatBurning #BiomedicalScience #HealthLectureMy favorite meal-replacement shake: https://gethlth.com (discount: BEN10)My favorite electrolytes (and more): https://redmond.life (discount: BEN15)My favorite allulose source: https://rxsugar.com (discount: BEN20)References:https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/randle-cycle Insulin Regulation of Ketone Body Metabolism: https://onlinelibrary.wiley.com/doi/10.1002/0470862092.d0308The Effects of a Ketogenic Diet and Exercise Interventions on Cognitive Function: https://faseb.onlinelibrary.wiley.com/doi/10.1096/fasebj.31.1_supplement.lb810(Due to character length constraints, not every reference is posted above.
