Expertise for Special Situations
Certain physiological and nutritional conditions in athletes require specialized knowledge and careful management.
RED-S & Low Energy Availability in Athletes
Chronic low energy availability affects multiple physiological systems, including hormonal function, immune health, and recovery. In athletes, it often presents as reduced performance, persistent fatigue, impaired sleep quality, and recurrent overuse injuries.
Persistent fatigue and poor recovery in Athletes
If training no longer produces results or you feel constantly fatigued, the cause may lie in the quality, timing, or adequacy of nutrition. Identifying the underlying cause is essential for restoring training quality and recovery.
Gastrointestinal Issues During Training and Competitions
Gastrointestinal discomfort, bloating, or gut symptoms can impair both training and competition performance. We identify the underlying causes and develop an individualized strategy to help the body better tolerate training and competition demands.
Eating Behavior Challenges in Athletes
Athletes often face pressures, restrictive patterns, or irregular eating behaviors. I guide eating habits and daily routines toward a balanced approach where nutrition supports performance without unnecessary stress.
Weight Classes and Body Composition for Performance Optimization
Body weight and fat mass changes are managed safely with performance as the primary focus. Energy intake, training demands, and recovery are carefully balanced to protect performance during the process.
Nutrition therapy and Weight Management
Nutrition therapy and weight management support is also available for athletes and physically active individuals whose goals extend beyond performance nutrition.

Frequently asked
What does a sports nutritionist do?
A sports nutritionist helps athletes and active individuals fuel training, improve recovery, and support performance through personalized nutrition strategies. This includes adjusting energy intake, meal timing, hydration, and recovery nutrition based on training demands, goals, and daily life.
How is the initial assessment in sports nutrition coaching conducted?
The assessment includes a discussion about training, goals, and daily routines, as well as a detailed nutrition history. Based on this information, I form a comprehensive picture of energy balance, recovery, and key development areas, allowing nutrition to be targeted directly toward improving performance.
Do I need laboratory tests?
Laboratory tests are not mandatory, but they can be useful in certain situations, e.g., when nutrient deficiencies are suspected, persistent fatigue occurs, illness is recurrent, or performance has declined. They may also help fine‑tune nutrition interventions (e.g. ferritin, vitamin D, HbA1c, thyroid markers).
If laboratory results are available, they will be taken into account when designing the nutrition plan.What do I need to bring to the first appointment?
It’s enough to bring an outline of your training week, example photos of typical meals are very helpful (not necessary), and any observations related to energy levels, recovery, or symptoms. Everything else we’ll go through together — no special preparation is required.
Can you work with underage athletes?
Yes. Nutrition coaching for underage athletes requires special care, as growth and development must always be prioritized. Ensuring adequate energy intake is essential, and all goals are planned in a safe and health first.
When appropriate, I collaborate with parents and coaches to ensure the athlete’s overall well‑being.How can gastrointestinal issues during competition be avoided?
Most problems are related to meal timing and food composition. High‑fiber or high‑fat foods consumed too close to the performance can cause symptoms. In some cases, inadequate hydration may also be a contributing factor.
The gut can be trained to better tolerate exercise stress through structured nutrition strategies practiced during training.Do you create competition‑day or ‑season nutrition plans?
Yes. I develop a detailed competition or game‑day nutrition strategies for fueling and preparation, energy and hydration, and recovery nutrition.
The plan is based on the specific demands of the sport, competition duration and intensity, and individual tolerance.Do I benefit from sports nutrition if I’m not elite?
Yes. Sports nutrition is not only for elite athletes. If you train regularly, sports nutrition helps ensure you fuel, recover, and adapt to training properly. A registered dietitian adjusts nutrition to your activity level, goals, and lifestyle, helping you improve performance, energy, and recovery without extreme diets or supplements.
