For 40 years you've been told 0.8 grams of protein per kilogram is "enough" but the scientists who contributed the reports behind the new 2025–2030 Dietary Guidelines say not a single study has ever shown that number beats eating more.
In this episode, Dr. Gabrielle Lyon sits down with Dr. Don Layman and Dr. Heather Leidy, the protein researchers who developed the scientific reports informing the new U.S. Dietary Guidelines, to discuss:
Why the guidelines reprioritized protein to a healthy range of 1.2–1.6 g/kg and why that still isn't technically "high protein"
Why you don't really have a protein requirement, but an essential amino acid requirement and what that means for your brain, mood, and antioxidant production
Who's quietly falling short: roughly 20% of women over 60 sit below the RDA, and adolescent girls are among the most consistently deficient
How to spot real protein on a label (Layman's 10-gram threshold) and why most "+protein" snacks are just fairy dust
What a higher-protein breakfast does to afternoon cravings, backed by fMRI brain-reward data
Walk away knowing how much protein you actually need, why "enough to avoid deficiency" and "enough to thrive" are two different numbers, and how to build every meal around protein first so you're covered on the nutrients that matter most.
