About Libby Parker

Hey, I’m Libby, thanks for being here!

I’m a New Yorker, originally from Minnesota, with an 11-year interlude on the central coast of California.

I owned a group dietitian practice, Not Your Average Nutritionist, in CA for 10 years, and am the author of 3 books, including my highly-regarded first book, Permission To Eat: A practical guide to working yourself out of an eating disorder during college, while celebrating the awesomeness that is you! I am now a eating disorder therapeutic consultant – being the matchmaker for clients and the treatment centers that best fit their needs. My mission is to help people recover from eating disorders and get back to finding their passion in life. I especially love working with college students and theatre people. 

My professional background: I am a “Certified Eating Disorders Specialist – Consultant” from the international association of eating disorder professionals, and have both bachelor’s and master’s degrees in Nutrition Science. I have been an eating disorder Registered Dietitian since 2012. I also have a minor in Leadership, but started as a musical theatre minor before switching schools.

I’ve worked in private practice, ED business development, corporate wellness (fun fact: my corporate wellness gig was at Diablo Nuclear Power Plant, and I’m probably the only dietitian with knowledge of nuclear energy), college nutrition professor, public health, personal and group fitness training, the wine industry, tea room manager, bed and breakfast attendant, and more. 

You can view my CV on Linked-In for more detail on my career journey. 

My performing background: I entered dance classes at the age of 3 thanks to my mom who loved to dance. I was brought up on the classic VHS musicals, and saw my first professional show (42nd Street) at the age of 5. I loved it so much I begged my mom to take me to see it again, and a theatre lover was born!

Throughout the years I took all kinds of dance classes, finding a real love in ballroom/social dance, especially swing (with lifts/aerials) in college. I lettered in Drama in High School, where I got my first real taste of being in musicals in a real theatre setting (and learned I am not cut out for tech work).

After becoming a RD, I got back into community theatre, beginning with A Chorus Line in 2014, and I never looked back. Since then I have performed in many local/regional shows, auditioned for Broadway shows, started working in film, and tried to keep up with dance and voice lessons as much as my career and life circumstances allow. It is when I am rehearsals or a show that I am fully present and alive.

I know you get it. 😉


How “The Broadway Dietitian” came about

While I was doing all of the theatre in CA, I had castmates ask questions about fueling for long rehearsals, eating before a show, and other questions about health.

Along with my own experiences, I took my knowledge of sports nutrition and dug more into research specific to dancers and performers. Finding there was very little on musical theatre/acting (basically anything beside dance), I took it upon myself to figure out what made sense for the lifestyle I had known and my clients were experiencing. 

My passion for musical theatre and desire for diet culture to go away blended into the perfect marriage of a brand. I had to give up my dream of performing on Broadway, but I get to stay with “my people” as the dietitian to entertainers and people across the theatre industry. I’ve had the privilege to help Broadway costumers, actors, dancers, and so may others take care of their bodies WITHOUT diets or weight loss talk. 

You are beautiful and worthy as you are. Let’s take care of that fabulous instrument of yours!
