About me

feldmanosoba

I 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.

EXPERIENCE

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.

PASSION

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.

ACCOMPLISHMENTS

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.

Jacek Feldman Dietetyk Sportowy

Jestem dietetykiem sportowym, specjalistą od dietoterapii, szkoleniowcem oraz autorem artykułów dla czasopism branżowych. Przez dłuższy czas uprawiałem czynnie sport biorąc udział w zawodach amatorskich w kickboxingu. Ze względu na swoje zamiłowanie do tego sportu, dążyłem do połączenia wiedzy z zakresu żywienia i sportów walki by stworzyć idealną metodykę dietetyczną dla fighterów.

Od wielu lat współpracuję ze sportowcami jako dietetyk. Zdobywałem doświadczenie pracując z najlepszymi zawodnikami sportów walki w Polsce. Są wśród nich zawodnicy najlepszej światowej organizacji MMA – UFC. Aktualnie kończę studia magisterskie z dietetyki na WSBiNOZ w Łodzi.  Ukończyłem studia licencjackie z psychologii w zarządzaniu na ALK oraz studia podyplomowe z poradnictwa dietetycznego na IŻŻ. Cały czas poszerzam horyzonty przez udział w licznych szkoleniach oraz konferencjach branżowych.

Ogromną radość sprawia mi poprawa stanu zdrowia moich pacjentów klinicznych poprzez zastosowaną dietę i suplementację. Cenię sobie przede wszystkim podejście holistyczne. Czytanie książek i badań naukowych utwierdziło mnie w przekonaniu, że studia to jedynie początek drogi zdobywania wiedzy i doświadczenia.

Współpracuję z czołowymi polskimi sportowcami zawodowymi (m.in. Maciej Sulęcki, Damian Janikowski, Marcin Łepkowski, Marcin Prachnio, Salim Touahri, Bartosz Fabiński). Pracuję na co dzień z reprezentantami wielu dyscyplin sportowych: maratończykami, triatlonistami, crossfiterami, piłkarzami.

  • It is my pleasure to recommend Jacek Feldman. The effects of our cooperation brought me to my knees. Thanks to Jacek I am rediscovering my body, he helps me break down the barriers. A well-balanced individual diet, adequate supplementation and commitment have surprised me very positively. Thanks to our cooperation, my results have significantly increased: strength, speed, regeneration, sleep are much more effective, cutting the weight (about 10 kg) for each fight is not a problem for me, which has always been a problem, despite cooperation with many nutrition specialists. I would recommend Jacek to everyone whose goal is, in particular increasing the sports results.

  • I have been working with Jacek Feldman since the beginning of 2016. Ever since I met Jacek, he infected me with his passion for dietetics and a healthy nutrition system. During our cooperation, we have already achieved our desired objective five times, Jacek was helping me with full commitment and his knowledge was a key element on the road to success. With a clear conscience and great respect I recommend Jacek as a dietitian to my friends, especially that in my life I have met many specialists who had a very schematic working style. Jacek is a exception to the rule, as a dietitian he approaches each case individually and puts his whole heart to help his clients.

  • I started working with Jacek Feldman in mid-2015. Thanks to his knowledge about nutrition, supplementation and also the functioning of the whole organism, my sports results, as well as the results of blood tests have improved significantly. Previous collaborations with other dieticians was based on poor observations of my body, only Jacek helped me to adjust nutrition and supplementation accordingly. His knowledge in the field of nutrition in martial arts is enormous, which has been proved by my well-being in recent months. I would recommend this dietitian to anyone who needs good preparation for the fight as well as anyone who cares about their health.

  • I have been practicing martial arts for 10 years. Preparations for each fight were always associated with sacrifices and tasteless starvation rations. Ever since I met Jack Feldman, cutting weight for the fights has become a pleasure. His diet is varied and meals are tasty. Everything is adapted to the lifestyle and to the intensity of training. Thanks to his advice I feel very good during the fight, which caused the improvement of my sports achievements.

  • I have already worked with many dietitians from Poland or the USA, but I have not seen such a specialist in this profession yet. Collaboration has been very good since the first days. He is a real pro. I recommend Jacek to every athlete who wants to move to the next level and to all physically active people who want to see how the professional athlete’s diet looks like.

I’ve never felt so good during the weight-cutting process and later during the fight itself, and it have always been a major problem for me during my previous matches. I definitely recommend Jacek Feldman as a specialist in dietetics and supplementation for both people training martial arts and those who want to enjoy good health and well-being.

  • I have been cooperating with Jacek Feldman for half a year. Thanks to the diet and supplementation prepared by Jacek, I could work even harder during the time of preparation, which results in a good form during the season. Better regeneration after training and lack of energy drops during the day are just some of the advantages of cooperation with a real specialist. Previously, I worked with several dieticians, but the diet plan prepared by Jacek was carefully refined and based on previous research. I would really recommend him!

  • I started working with Jacek Feldman less than a month before my fight at FEN 16 and I have to admit that if it wasn’t for his help and the great knowledge about proper nutrition, it would be hard for me to cut the weight, especially which it was the first time I fought in weight of 61 kg. Previously I had all my fights in 66 kg category. It was quite a challenge for me and for Jacek, but we did it. Jacek was very supportive and very involved. It is certainly a professional that I can recommend with a clear conscience!

  • I recommend Mr. Jacek Feldman as a diet therapist and sports nutritionist. I have been working with Mr. Jacek for several months and in this short time he helped me to improve my metabolic health, which due to bad functioning excluded me completely from a sports career for more than a year. From the moment I started to follow Mr. Jacek’s recommendations, my blood test results, and most of all my well-being, improved significantly and I returned to a full-size training cycle. By the way, my body composition has also improved significantly. As a personal trainer and a steeplechase runner, I really appreciate the professional and individual approach that characterizes Mr. Jacek Feldman.

  • I would like to recommend Mr. Jacek Feldman. Since the beginning of our cooperation, the quality of my workouts has moved to a whole new level. Regeneration is much faster, the strength is growing. CrossFit is a very demanding discipline for both the body and the mind. Thanks to the proper diet and supplements composed by Mr. Jacek, I am able to do every workout according to the plan. In addition to training myself and others, I am also the mother of a two-year-old girl, and thanks to the appropriate diet I am able to succeed in all of these roles.

  • It’s a pure pleasure to work with Jacek. I am an experienced athlete and it was not a first time for me to cut weight, but only in cooperation with Feldman Nutrition I’ve experienced how it is to lose weight and feel good at the same time, and above all, to not be stressed out during the whole process. Everything is totally professional with an individual approach to me as a competitor, starting with a diet and supplementation through advice how to quickly regenerate the body between heavy training sessions till how to regain strength immediately after weigh-in. I would highly recommend!

  • I would like to recommend Jacek Feldman to all people who are focused on a specific goal in martial arts. Jacek is a professional with an individual approach, and consultation with him is a source of knowledge that allows you to enter a higher and higher level. He helped me to go straight with health and enabled me to build a specific form. Without his support, it would be Sisyphean for me, and the research results speak for themselves. I can train more intensively and more effectively, and sticking to recommendations and good eating habits has simply become nice for me. I heartily recommend using Jacek's knowledge, it is an effective base for building sports achievements.
