We work with both people who want to achieve the set goals and professionals who care about the best results.
The highest level of care and full professionalism. I had the opportunity to meet many specialists in dietetics, but Jacek was the only one who was able to help me deal with my digestive problems. With his help, I also managed to reduce body fat, which resulted in better sports results. I honestly recommend!
I started working with Jacek Feldman when we decided to return to the cruiserweight category after 10 years. In practice, this meant losing 18 kg, which thanks to Jacek’s knowledge and my discipline.

I would recommend Jacek to everyone whose goal is, in particular increasing the sports results.
With Jacek I was preparing for the most important competition in my life – the World Championships. I always thought that preparing couldn’t be done more, but Jacek dispelled my doubts and prepared me for my life shape. I felt so calm that the process of making weight was planned in every detail. The very cooperation and control with him is sensational, and in the end I became a world champion!
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. From the moment we started collaborating, my achievements have grown significantly. The proper diet and supplementation that Mr. Jacek applied to me is really great and effective.

I fully recommend this diet and supplementation specialist.
I have been working with Jacek Feldman for a year. During the cooperation I have experienced a multiple improvement of my sports results, thanks to the nutrition plans created by Jacek.

You can see the results and results of fights yourself. I started working with Jacek just before my third professional fight in MMA for the Polish KSW Federation. A piece of good work. I think that this cooperation is just developing and there will always be juicy fruit in the form of won fights. Good diet, weight loss and the whole procedure preparing me for fights is the best so far in my sporting career. I can easily recommend Jacek Feldman as a specialist and a man appropriate in his profession. Regards, thank you Damiano.
I started working with Jacek with the transition to profession. We base our work on measurable parameters of the respondents before the start of preparations for the fight and regularly in the preparations themselves. I was able to go through the preparations without any problems and obtain the weight limit (I managed without saunas or bathtubs). It also draws attention to the neurological aspects in athletes, i.e. prevention of brain damage and well-being throughout the training process. It is a pity that I did not cooperate with Jack years ago while fighting in kickboxing – I would save a lot of health and nerves in preparations for the fight and reaching the weight limit. 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.

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.
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 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.

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 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 have been practicing martial arts for 10 years. Preparations for each fight were always associated with sacrifices and tasteless starvation rations.

Thanks to his advice I feel very good during the fight, which caused the improvement of my sports achievements.
