Licensed dietitian specializing in sports nutrition and eating disorders

CLIENTS & AFFILIATIONS

Registered dietitian, certified specialist in sports nutrition, blogger, runner and food coach.

I’m Amy Stephens, MS, RD, CSSD, CEDS, a sports dietitian with more than 25 years of experience helping athletes improve performance, recover from injury, and build a healthier relationship with food. I work with athletes from a variety of sports, including swimming, gymnastics, soccer, basketball, rowing, cycling, and triathlon, with a special focus on distance runners and endurance athletes. I provide nutrition counseling in New York City and virtually across the country.

I believe athletes perform their best when nutrition is flexible, practical, and sustainable. My goal is to help you fuel with confidence, spend less time worrying about food, and have more energy to enjoy both your sport and your life. Whether you’re training for your first race, competing at the collegiate level, chasing an Olympic Trials qualifier, or trying to feel stronger during workouts, I’ll help you develop a nutrition plan that fits your lifestyle and supports your goals.

As a Board Certified Specialist in Sports Dietetics (CSSD) and a Certified Eating Disorders Specialist (CEDS), I help athletes navigate everything from performance nutrition and race day fueling to RED-S, underfueling, body image concerns, and disordered eating. My approach is always food first and evidence based, with an emphasis on building habits that athletes can maintain for years, not just one season.

In addition to my private practice, I served as New York University’s first sports dietitian, where I worked with athletes across every varsity sport and helped support the women’s cross country team during its first NCAA Division III National Championship season. Today, I work with recreational runners training for their first marathon to professional athletes, including runners with Empire Elite Track Club.

I frequently collaborate with sports medicine physicians, therapists, coaches, physical therapists, and other members of an athlete’s healthcare team to provide comprehensive, individualized care.

In addition to working with clients, I speak at conferences and events across the country and regularly present for New York Road Runners (NYRR). My insights have been featured in Runner’s World, The Washington Post, Wall Street Journal, and The New York Times, where I enjoy translating the latest sports nutrition research into practical advice.

I earned my undergraduate degree from Syracuse University and my master’s degree in Clinical Nutrition from New York University. I’m also an avid runner and have completed ten marathons, including two Boston Qualifiers, and two ultramarathons, so I understand firsthand the challenges and excitement that come with training for endurance events.

Whether you’re looking to set a personal record, recover from an injury, restore your period, improve your relationship with food, or feel stronger in training, I’d love to help you build a fueling plan that allows you to perform your best and enjoy the process along the way.

Ozempic, GLP-1s, and Sport Nutrition: What Young and Active People Should Know

August 11, 2026

Recently, my college-aged daughters asked me about weight loss drugs. Some of their friends were using them; they were bombarded by advertisements, and the topic was often brought up when socializing. As a sports dietitian who specializes in eating disorders, I had a lot to say on this topic. I gathered their questions and did my own research to provide the most up-to-date and accurate information that I thought would be helpful for others to read, too.

Breakfast ideas for high school athletes

Breakfast is often one of the most overlooked meals for teen athletes, yet it can have a major impact on both academic and athletic performance as well as growth and overall health.

COMMON NUTRITION MISTAKES RUNNERS MAKE (AND HOW TO FIX THEM)

Training for a marathon takes a lot of time and consistency. Most runners spend months building mileage, following a plan, and dialing in their workouts. One thing that often gets overlooked is nutrition. While runners put a lot of effort into training, many are unknowingly making fueling mistakes that are completely preventable. A lot of runners don’t realize how much fueling impacts performance, but it plays a major role in both training and race day.

When Should You Use Electrolytes for Running?

Ferritin Levels for Athletes: What’s the Optimal Level?

May 5, 2026

If you’ve ever been told your iron levels are normal but you still feel fatigued, your ferritin might tell a different story. Ferritin is an important blood marker that indicates your iron stores, and for athletes, “normal” isn’t necessarily optimal for performance. Normal levels may be adequate but if you are an athlete, higher ranges are important to optimize performance.

I really enjoyed working with Amy-she helped me master nutrition, hydration, and recovery as a runner but also in my everyday life.
