In this mini lecture, Dr. Bikman explains the powerful metabolic effects of long-chain omega-3 fatty acids—specifically EPA and DHA—on fat metabolism and muscle growth.
Ben starts by clarifying the difference between plant-based ALA and animal-based EPA/DHA, emphasizing that only the latter provide meaningful metabolic benefits. Plant-based ALA converts very poorly into EPA/DHA, making direct consumption of animal sources (like fatty fish or pasture-raised meats) crucial for those seeking metabolic improvement.
Dr. Bikman then explores how EPA and DHA enhance fat burning by stimulating mitochondrial biogenesis and improving mitochondrial efficiency. They increase the expression of CPT1 (the fat-shuttling enzyme) and promote mitochondrial uncoupling through UCP1 and UCP3, helping the body burn more fat—even at rest. He also describes how omega-3s literally become part of mitochondrial membranes, improving their fluidity, fuel processing, and ATP production without increasing oxidative stress.
Shifting to muscle, he explains how omega-3s amplify the muscle-building response to insulin and amino acids by enhancing mTOR signaling. Studies show omega-3s can significantly boost muscle protein synthesis and preserve muscle mass during injury or disuse. They improve membrane fluidity and cell signaling, making muscles more responsive to growth stimuli.
Ben concludes with a practical recommendation: daily intake of 2–4 grams of combined EPA and DHA from animal sources (like fish or high-quality supplements) is ideal. He reminds viewers that plant-based omega-3s will not deliver these same benefits and encourages consistent intake over time for best results.
