New Evidence for the Substrate-Driven Model I came across a fascinating recent study this week in Nutritional Neuroscience that really validates something I’ve been thinking about for a while. Lima and colleagues just published research showing how diet and exercise reshape the endocannabinoid system in the brain. It all fits beautifully with what I call the substrate-driven model of ECS function. Let me walk you through what they found and why it matters. The Study: Diet, Exercise & Brain ECS The team took young rats and divided them into groups. Some got standard lab chow, others got a “palatable diet” (think: high in omega-6 fats and sugar, like a Western diet). Some rats didtreadmill training for eight weeks, others didn’t. Then they looked at CB1 receptors and NAPE-PLD enzyme levels in three key brain areas: • Hypothalamus – your energy regulation center • Frontal cortex – handles reward and decision-making…
