Diana K. Rice, RDN, LD

Diana is a registered dietitian who joined RDbyyourside in the fall of 2017. She is a recent transplant to St. Louis, having spent most of her career in the New York City metro area.


Nutrition is a second career for Diana. She studied journalism in her undergraduate program at New York University and went on to work for a handful of NYC-based publications prior to realizing her passion for nutrition and studying to become an RD. Many of the skills Diana developed as a journalist now inform her work in nutrition counseling, especially asking thoughtful questions and relying on evidenced-based information.


Diana earned her B.S. in Dietetics from the University of Northern Colorado and completed her dietetic internship with Cedar Crest College, where she graduated with highest commendations. After becoming an RD, Diana joined The Monday Campaigns, the non-profit behind the well-known Meatless Monday initiative. There, she worked to communicate the organization’s messages of incorporating small, meaningful changes into your daily routine and treating each new week as an opportunity to improve your health to a global audience.

At The Monday Campaigns, she was the project lead for The Kids Cook Monday, a campaign about cooking with kids and family dinners. Soon after having her first child, Diana also began working with fellow moms to help them have healthy pregnancies, feed their children well and learn to love and nourish their postpartum bodies. In early 2017, Diana founded the blog and nutrition consulting business The Baby Steps Dietitian, where she works to inspire busy parents to develop a healthy relationship with food through easy recipes, effective child feeding strategies and body positivity.


Diana relocated to St. Louis shortly after having her second child and is excited become involved in the St. Louis dietetics community. She is a member of the Academy of Nutrition and Dietetics as well as the Nutrition Entrepreneurs and Pediatric Nutrition dietetic practice groups.
