Summary
Today, I welcome Dr. Heather Leidy to The Dr. Gabrielle Lyon Show for an in-depth conversation about the evolving landscape of nutrition science. Together, they tackle pressing topics like the future of the U.S. Dietary Guidelines, the impact of protein timing, and the importance of protein quality in supporting health and mitigating frailty. Dr. Leidy highlights recent research that explores behavioral strategies for sustainable weight management, the role of animal-sourced foods in nutrient adequacy, and the effects of GLP-1 medications on diet and health outcomes.
Key Discussion Points:
- The critical role of breakfast in satiety and long-term health
- Why the food matrix matters when evaluating protein sources
- The untapped potential of family-based breakfast interventions
- Implications of GLP-1 medications on protein needs and behavioral strategies
- Addressing the nutrient gaps in plant-based diets and rethinking food waste

| 0:00.0 | Welcome to the Dr. Gabriel Lyons Show, where cutting edge science meets innovation and practical application for everybody. |
| 0:07.3 | In today's episode, I sit down with one of my favorite scientists, Dr. Heather Lydie. |
| 0:13.5 | In this episode, we discuss all about dietary protein guidelines, also dietary proteins role on satiation and so much more this episode will blow |
| 0:26.5 | your mind in terms of how the research is conducted and distributed in ways that affect our world |
| 0:33.8 | please join me in conversation with Dr. Heather Lydie. |
| 0:43.9 | Dr. Heather Lydie, thank you so much for joining me today. |
| 0:47.0 | Oh, it's great to be here. |

| 0:54.3 | tell you, I have been such a fan of your work. Well, thanks. I did my fellowship at Washoe in |
| 1:00.5 | nutritional sciences out of Sam Klein's lab. And when I started looking at your data, talking about |
| 1:06.9 | breakfast skipping and adolescence and this nutrition, protein, and behavior, it really, |
| 1:15.0 | really changed everything for me. So thank you so much for all the work that you're doing. |
| 1:18.4 | Oh, thanks. No, it's a great topic. It's been a great area of research for me and there's still |
| 1:23.1 | a lot to uncover. Yes, protein, satiety, which we're going to talk all about. |
| 1:27.8 | You know, your research, you are an associate professor at the University of Texas at Austin. |
| 1:32.5 | You were at Purdue before and you were at the University of Missouri right before that. |
| 1:37.9 | And you've really paved the way when it comes to protein and satiety. |
| 1:43.2 | You are also part of the 2020 dietary guideline committee. |
| 1:48.3 | And I want to start there. Sure. Please tell me a little bit about your role on the 2020 |
