About me

Jacek Feldman Dietetyk Sportowy
am a sports nutritionist, a specialist in diet therapy, a trainer and an author of articles for professional magazines. I was actively practicing sport for a long time, taking part in amateur kickboxing competition. Due to my passion for this sport, I decided to combine knowledge in the field of nutrition and martial arts to create the ideal dietary assessment method for fighters.


I have been working as a dietician with professional athletes for many years. I gained experience working with the best fighters in Poland. Among them there are fighters from the world’s best MMA organization – UFC. I completed BA studies in psychology at ALK and postgraduate studies in Nutritional guidance at IŻŻ. I am currently completing my master’s degree in dietetics at WSBiNOZ in Łódź. I broaden my horizons constantly by participating in numerous trainings and sport business conferences.


It is a huge pleasure for me to improve the health of my clinical patients through the diet and supplementation used. I am passionate about implementing dietary solutions. I particularly value the holistic approach and natural medicine. Reading books confirmed my beliefs that universities are the beginning of true knowledge.


I collaborate with leading Polish professional athletes (including  Maciej Sulęcki, Bartosz Fabiński, Marcin Łepkowski, Marcin Prachnio, Jan Błachowicz, and Patryk Lipski). I work every day with representatives of many sports disciplines: marathon runners, triathletes, crossfitters and footballers. I participated in many domestic and foreign trainings.


The more you know, the more remains to know and it still comes to you.
