Hi, I’m Eszti!
I’m a sports-specific dietitian, personal trainer, certified yoga instructor, and amateur endurance athlete.
Through consultations, personalized nutrition planning, and educational programs, I help support performance development, recovery, and injury prevention — with a holistic approach that combines nutrition, strength training, and mobility.
Personal Sports Exprience
From personal experience, I know how important proper sports nutrition and well-planned fueling strategies are for performance and recovery. I also believe that strength training, foam rolling, stretching, and yoga should be essential parts of every athlete’s daily routine.
About
My name is Eszter Halas, founder of Athletes’Fuel, sports-specific dietitian, personal trainer, certified yoga instructor, and amateur endurance athlete.
I have completed a full-distance Ironman, run 12 marathons, finished two trail ultramarathons, and participated in several Spartan Races. Through personal experience, I understand how important proper sports nutrition and well-planned fueling strategies are. I also strongly believe in integrating strength training, foam rolling, stretching, and yoga into every athlete’s daily routine.
For nearly 10 years, I have been involved in sports science from multiple perspectives. For years, I worked with performance monitoring, movement and video analysis software, and field testing, primarily with football players and other team sport athletes. In addition, I have supported athletes and teams through sports anthropometric assessments and sports selection counseling.
As a sports-specific dietitian, I mainly work with professional and amateur team sport and endurance athletes. I have been involved in football as a sports professional since 2017, and spent four years at Ferencvárosi TC working with professional football players as a sports-specific dietitian. I currently contribute to Nutri8 through professional educational content. Previously, I worked as a sports dietitian at Ensport and collaborated with the Hungarian Anti-Doping Group during the 19th FINA World Championships in 2022.
Through the Synlab Academy, I also completed training in sports diagnostics and laboratory diagnostics consulting, which provided me with deeper insight into the laboratory parameters required for outstanding athletic performance.
In addition to consultations and personalized meal planning, I support athletes and sports professionals through lectures and educational programs. Alongside private presentations, I am proud to have been an instructor at Fitness Company since 2022. I also participate as a guest lecturer in the sports-specific dietetics program at the Hungarian University of Sports Science. In 2023, I had the opportunity to present at the Hungarian Sports Medicine Society Congress 2023, and for one and a half years I taught courses at Probody Studio and the Hungarian Sports Rehabilitation Association (MASE). Since 2024, I have been working at Wáberer Medical Center and MyWay Mental Center as part of multidisciplinary professional teams. I will soon begin further professional collaborations with outstanding sports professionals, which is a great honor for me.
Over the years, I have led SpinRacing, TRX, functional, Gymstick, senior fitness, and personal training sessions. I also worked as a spinal trainer, which further strengthened my preventive and injury-prevention approach to coaching. Currently, I work with amateur and recreational athletes as both a yoga instructor and personal trainer. The knowledge I gained as a coach further enhances the effectiveness of my professional work in sports nutrition.
As a coach and sports-specific dietitian, my mission is to support fellow athletes in achieving their goals and improving their performance effectively. My primary goal is to teach athletes how to use nutrition to maintain both their performance and health at the highest possible level. With a well-structured nutrition strategy and meal plan, training sessions and competitions can be significantly supported, allowing athletes to develop and perform more effectively. A properly designed nutrition plan also improves recovery and sleep quality, helping to prevent injuries and maintain high-level performance over the long term.

Who I Work With
How Does a Consultation Work?
Get in Touch
Contact me via email or message, and we will arrange a suitable time for your consultation.
Initial Assessment
Before the consultation, you will receive a detailed questionnaire and a nutrition diary to help me gain a clear understanding of your current health status, eating habits, and goals.
If you have any previous medical records or test results, you are also welcome to send them in advance.
Consultation
The consultation can take place either in person or online. During the session, we will discuss your goals — such as performance improvement, body composition changes, recovery, and overall well-being — as well as the areas where your nutrition may need adjustment.
If you would like, I can then create a fully personalized nutrition plan tailored to your individual needs and goals.
