## Resource

For decades, we've been told that eating less fat is one of the healthiest things we can do. That advice reshaped the foods we buy, the way we think about weight loss, and even how parents feed their children. But what if we misunderstood fat in the first place? In this episode, nutrition researcher Dr. Arne Astrup traces how the war on fat began, why many of its core assumptions haven't held up under decades of research, and what we've learned instead. Rather than asking whether fat is "good" or "bad," he argues that the more useful questions are: What foods actually keep us healthy? Why do some people gain weight more easily than others? And what happens when we reduce nutrition to single nutrients instead of whole foods?
