#147 - Hussein Yassine, M.D.: Deep dive into the "Alzheimer's gene" (APOE), brain health, and omega-3s Feb 01, 2021

Show notes

Hussein Yassine is a physician and researcher who studies brain lipid utilization in the context of finding preventative measures for cognitive impairment, specifically Alzheimer's disease (AD). In my conversation with Hussein, we begin with a fundamental coursework in brain biology—including its architecture and energy systems. We go on to discuss what these systems look like when something goes wrong and cognitive decline ensues. We talk about the evolutionary origins of the ApoE genotype, with specific attention to the ApoE4 allele and its association with AD. We spend time discussing ApoE4 implications for the brain's fuel utilization, notably omega-3 fatty acids: EPA and DHA. We briefly pivot to the implications of recent omega-3 trials for cardiovascular disease and return to what we currently understand about EPA/DHA and brain health; we contemplate potential dietary interventions across the lifespan to preserve and prolong cognitive function.

We discuss:

Hussein's Background and introduction to brain composition (3:00);
The blood-brain barrier and brain filtration (8:00);
Lipids and brain function (13:00);
How the brain utilizes energy (18:00);

#144 - Phil Maffetone: Optimizing health and performance through maximal aerobic function Jan 11, 2021

Show notes

Phil Maffetone is an author, health practitioner, and coach with decades of experience helping everyone from amateurs to world-class athletes optimize their health and performance. In this episode, Phil explains the importance of developing the aerobic system, defines maximum aerobic function (MAF), and explains how to determine your MAF heart rate. He then demonstrates how to integrate that into a training protocol which is designed to help people move faster at a sub maximum heart rate and increase fat utilization as the primary source of fuel—emphasizing the importance of nutrition on one's capacity to oxidize fat. Phil also extracts training insights from the amazing feats of world-class marathoners, explores the impact of a low-carb diet on one's capacity for high intensity exercise and anaerobic performance, and explains the downstream effects of being "overfat."
