Dr. Nina Teicholz | America's Metabolic Decline: The High-Cost of Low Fat | The Metabolic Link Ep 80
The Metabolic Link
Personal Impact of This Work
Victoria asks how the research changed Nina's life; Nina describes improved health, family dietary shifts, and growing institutional skepticism.
For over fifty years, Americans have been told that cutting fat was the key to better health. Yet after decades of low-fat guidelines, rates of obesity, diabetes, and metabolic dysfunction have skyrocketed - now affecting more than 88% of the population.
In this episode of The Metabolic Link, Victoria Field sits down with Dr. Nina Teicholz, science journalist and author of The Big Fat Surprise, whose decade-long investigation into nutrition science uncovered how flawed evidence and policy decisions shaped the way we eat. Her research reveals a troubling gap between the science and the guidelines meant to protect public health.
Answered in this episode:
- How did you transition from investigative journalism into becoming one of the leading voices challenging nutrition policy?
- What specifically makes the original science behind the low-fat diet hypothesis so weak?
- How did Ancel Keys' controversial research become official U.S. nutrition policy?
- What were the metabolic consequences when Americans replaced dietary fat with carbohydrates?
- How did seed oils come to dominate the American food supply, and what are the metabolic implications?
- What do randomized controlled trials reveal about low-carb versus low-fat diets for metabolic health?
- How has industry funding influenced the direction of nutrition research and policy?
This conversation provides a rigorous examination of how weak associational data became entrenched policy, the metabolic consequences of replacing saturated fats with refined carbohydrates and seed oils, and what the path forward looks like for evidence-based nutrition science.
