DESCRIPTION

In this episode, I sit down with pro natural bodybuilder and future registered dietitian James Brennan to break down what most people get wrong about evidence-based nutrition. We dive into why social media makes health so confusing, how to bridge the gap between science and real life, and why focusing on behaviors over body weight leads to better long-term results. We also get into misinformation around seed oils, the truth about insulin and fat loss, the role of AI in nutrition research, and how improving school food systems could actually change the health of future generations.
