Get to know me
I'm a Board-Certified Sports Dietitian (MS RD CSSD) with over a decade of experience helping active people achieve their nutrition, health, and fitness goals. I'm also a longtime endurance athlete, with a passion for trail and ultra running.
I spent my first two years as a dietitian working in a hospital, counseling patients with acute and chronic medical problems. The clinical setting wasn't my cup of tea, but it taught me how to support an athlete as a whole person.
I've worked as a sports dietitian in private practice ever since, helping countless teenage and adult clients overcome their nutrition challenges. I would love to teach you how to fuel for long-term health and performance, so that you can do what you enjoy for as long as possible!
Hi! I'm Claire Shorenstein.
I first fell in love with running as a member of my high school’s cross-country team. As someone who focused intensely on academics and music, I never considered myself very athletic. Turns out I found immense joy in exercise and competition!
I discovered distance running 10 years later while living in London, and it changed my life. I felt stuck in a corporate job that I hated, and marathon training gave me a sense of purpose. It also inspired me to become a running coach and Sports Dietitian. ​​
My Story
As a new endurance athlete, I had NO clue how to fuel myself. My eating disorder that I had as a teenager and young adult was behind me. However, I still struggled with disordered eating thoughts and behaviors and obsessed about my weight.
​​
This was partially because I believed the BS that "lighter = faster." I didn't realize that weight is just one among MANY different factors that impact athletic performance. I also had no idea how much energy my body needed to be healthy and perform well.
​
The result was chronic underfueling, which led me to feel and run like crap while sucking all the fun out of my hobby. I struggled with burnout, fatigue, injury, poor performance, and a host of other negative mental and physical symptoms.
It took a lot of time and work on my own nutrition, body image, and mindset, but it has paid off big time.
Instead of eating the bare minimum to scrape by, I learned to embrace fueling myself to my full potential. My running mojo came back. My gut stopped being pissed off all the time. My mood and health markers improved. I even hit some PRs!
​
All of this continues to be a work in progress, as my body (and life generally) keeps changing. It's 100% worth the effort.
The nutrition space can be confusing, overwhelming, and at times, contradictory. I help you navigate YOUR unique world and keep things as simple as possible to set you up for success.
​
I offer a variety of nutrition services that will help you create and implement a personalized, flexible, and sustainable nutrition plan that works for YOU, as a human first and athlete second.
