This Will Change Your Mind on Ultra-Processed Foods (Harvard MD PhDs Discuss)
17th September 2025
Today’s guest is David Ludwig, MD, PhD, an endocrinologist, pediatrician, and international thought leader in obesity medicine and metabolic health. He’s also a treasured mentor of mine from my time at Harvard Medical School. In this episode, we discuss his new paper in the New England Journal of Medicine on ultra-processed foods and why “simple” is the enemy of metabolic health. We explore the science of nutrition, weight loss, and food quality, challenging conventional wisdom about diet and metabolism. If you’re courageous enough to listen all the way through, this conversation will expand your perspective, change the way you think about food, and inspire a healthier relationship with eating.
You are what you eat. So this is important.
