Episode notes
A Mentor's Lifetime Work Shaped Guidelines
- Gabrielle Lyon described studying protein since 1999 and being mentored by Don Lehman, a leading protein expert.
- She teared up on stage when his decades of work influenced the new Dietary Guidelines.

- Declines in saturated fat intake since the 1980s didn't reduce heart disease; carbohydrate and processed food intake rose instead.
- The saturated-fat story is complex and requires personalized interpretation rather than blanket demonization.

- Design plates and meals so you can eat protein at every opportunity without obsessive measuring.
- Use simple rules (plate thirds, protein-first) to make protein intake practical in daily life.
