In this episode we discuss:   How the Randle Cycle actually works Whether eating carbs and fats in the same meal causes weight gain and insulin resistance The efficiency of using fats as a fuel vs carbohydrate How stress impacts fuel usage in the mitochondria How to determine the optimal amount of carbs and fats in your diet Check out the Energy Balance Solution program here: https://www.jayfeldmanwellness.com/solution/ Click here to check out the show notes: https://www.jayfeldmanwellness.com/eb-139-the-truth-about-the-randle-cycle-why-you-can-eat-carbs-and-fats-together/   Timestamps: 0:00 – intro  0:53 – misconceptions regarding the Randle cycle in the alternative health world  4:57 – what is the Randle cycle?  7:06 – what most people get wrong about the Randle cycle  10:44 – fat oxidation leads to increased ROS production and a decreased NAD+/NADH ratio  16:29 – how fat oxidation inhibits the utilization of carbohydrates  21:03 – the Randle cycle shows the benefits of burning carbs for energy  25:56 – how fat oxidation inhibits the utilization of carbohydrates cont’d  26:57 – metabolic dysfunction, not glucose, drives insulin resistance and aging  32:07 – fat metabolism causes a buildup of citrate which reduces glucose uptake and utilization  38:39 – how glucose oxidation inhibits the uptake and utilization of fats  45:32 – whether you can “activate” or “deactivate” the Randle cycle  47:22 – glucose oxidation leads to an optimal NAD+/NADH ratio and decreased ROS production  52:08 – the protective effects of CO2 and why the brain can’t use fats as a fuel  53:17 – whether we should strive for metabolic flexibility  55:55 – fat metabolism and ketone production as a mechanism for energy conservation and glucose sparing  1:00:02 – insulin resistance as a state of excess fat metabolism and decreasing fat metabolism or stress hormones improves this state  1:05:28 – should we avoid eating carbs and fats together due to the Randle cycle?  1:08:08 – different cells, tissues, and organs can use different fuels at the same time
