The DNA Talks Podcast The Future of Nutrigenomics: Where DNA Meets Better Weight Health and Nutrition with Ashley Koff RD
Happy New Year! This time of the year, most declare their resolutions - a huge majority including diet and weight loss, but what is the best way to do it?
In this episode, our Chief Science Officer, Dr. Krista Kostroman, N.D., is joined by Ashley Koff, R.D., the founder of The Better Nutrition Program (BNP), the nutrition course director for UC Irvine’s Susan Samueli Integrative Health Institute’s Integrative and Functional Medicine Fellowship, and a faculty member at the Integrative and Functional Nutrition Academy (IFNA), where she teaches “An Integrative and Functional Nutrition Approach to Obesity and Weight Management.”
She is also the author of the recently released book Your Best Shot (HarperOne, Jan. 6, 2026). With over 25 years of practice, Ashley leads a transformative movement in personalized nutrition — turning “better, not perfect” choices into practical, sustainable strategies that create meaningful health outcomes. Through patient stories and personal experience, she demonstrates that optimal health isn’t just possible — it’s essential to living a full life.
Her work has been recognized widely: she was named one of CNN’s Top 100 Health Makers, featured in InStyle as “Hollywood’s Leading Dietitian,” and selected as Westin’s Global Nutrition Ambassador.
