About this episode

Dr. Bikman discusses mitochondrial uncoupling and its impact on calorie burning and fat tissue physiology.

📢 Ask Dr. Bikman’s Digital Mind (multilingual): https://benbikman.com/ben-bikmans-digital-ai-mind 📢 Dr. Bikman’s Community & Coaching Site: https://insuliniq.com In this Metabolic Classroom episode, Dr. Bikman explains mitochondrial uncoupling, a process where cells burn fuel without converting all of that energy into usable ATP. Normally, mitochondria are “coupled,” meaning fuel burning is efficiently converted into cellular energy. But when mitochondria become uncoupled, some of that fuel is released as heat instead—like revving a car engine while it’s in park. Ben explains that this process is especially important in fat tissue. White fat is designed for energy storage and tends to be tightly coupled, while brown fat is rich in mitochondria and uncoupling proteins that burn fuel to generate heat. He then connects this physiology to insulin, showing that insulin appears to make fat-cell mitochondria more tightly coupled and efficient, lowering energy expenditure and making storage easier. The opposite happens when insulin is low and ketones rise. Research from Dr. Bikman’s lab shows that ketones, especially beta-hydroxybutyrate, can increase mitochondrial respiration in…
