About me: Ondrej Matej BSYA (Nutri.)

My journey to becoming a nutritionist and personal trainer began many years ago when I realised that a balanced diet is an essential part of spiritual and mental health, and physical fitness. After trying different diets such as raw food, vegan, vegetarian and others I became aware of the nutritional gaps in most modern diet plans, including the lack of some essential vitamins, minerals, proteins and other compounds which are necessary for good health and longevity.

After sharing this knowledge amongst my family and friends I noticed significant improvements in their appearance and overall well-being. This experience motivated me to study and gain a diploma as a nutritional therapist and personal trainer and start my business OMnutritionist. The goal of all my training and advice is to make you understand your body and its needs, to get you back in to balance with yourself.

The decision to train with Ondrej was the best decision I ever made. He is a supportive, talented and fun person to work with. Ondrej didn’t just help me get fitter, he helped me understand why it was important and how I had to change my habits and attitude as well as what I did in the gym. I went from being someone who could barely do 8 burpees to someone who could do 160! I would also recommend his nutritional advice and supplements to anyone making a whole life commitment to being fit and healthy, and taking control of the busy and stressful urban environment we all live in. The hour with Ondrej each day is an oasis of calm and happy progress towards stretching but rewarding personal goals, with someone who cares about helping you reach them.

I was overweight, drinking too much and general pretty unfit. Within 6 weeks, I have lost a stone in weight, can lift my own body weight (previously unthinkable!) and run 10 kms. Ondrej’s combination of nutrition (I now have a fresh fruit superfood smoothie every morning) with a varied exercise programme makes you feel great

I started Ondrej’s 8 weeks Nutritional programme and the results I’ve had are nothing short of amazing! I arrived in a very stressed state suffering among other things an undiagnosed candida infection and several other digestive ailments. I was constantly bloated and in pain, I felt sluggish, lethargic and depressed. My skin was dry and I had a permanent headache and dark shadows around my eyes. I had seen several doctors and no one seemed to understand what my problem was. They just gave a number of pills and antibiotics to take in which were only making my overall condition worse. Little I knew back then about the role that diet plays in our overall sense of well being. I learned about Ondrej’s programmes and I decided to give it a try.

I found in Ondrej all the answers I was looking for and he was able to understand immediately not only my physical challenges but also my emotional stress. I started his nutritional programme and after only one week I was thrilled to find out that my headaches and fatigue had gone away. I felt as though I was finally on the right path to a healthier lifestyle. And I was!

Now after 4 weeks of completing the programme my whole body feels healthier and reinvigorated, I am not longer bloated or tired, my candida is completely healed and I feel full of energy all the time. My quality of life has improved beyond words and my sense of wellbeing has benefited enormously. Thanks to Ondrej’s programme, life has become enjoyable once more.

I found Ondrej to be exceptionally helpful and supportive. He was extremely professional, yet highly approachable, positive and knowledgeable. The nutritional programme he created for me was simple, dynamic and fun. It was so easy to follow it and I feel so good that I want to stay with it forever! I would definitely recommend him to you whether you’re after mental, physical, nutritional or emotional guidance.

I have nothing but good things to say about Ondrej’s nutrition and personal training systems, I started with him on my nutrition as like most people I was over weight, he guided me gently to a new holistic way of eating after which I did his 12 week personal training course, all I can say

“With Ondrej’s guidance I’ve managed to transform my lifestyle and regain the energy I was missing in my everyday activities. With dedication and attention to my specific needs and limitations, Ondrej gave me just the healthy boost I needed.”

“What I like about Ondrej is that he doesn’t take life too seriously and makes the whole thing fun..!!! At my age there are things I simply will not do and Ondrej’s special mix makes life practical – simple. His knowledge on resistance training and nutrition is wide and flexible which brings longevity to the whole thing for me. The other thing that I find great is that I can just chat to him about almost anything, his experience is quite varied, interesting. Ondrej has become a friend I can really communicate with.

I decided to sign up to OMnutritionists 12 week programme as I was very reluctant to take the antibiotics that my doctor prescribed as a last resort. Three days into the programme, no new acne developed, and now 2 months in, my skin has been incredible. Not only has my complexion cleared but the overall quality and colour of my complexion has made people remark on it. I’m very, very happy with the results and I can’t believe that the programme works by adding food to my diet, meaning I can still eat what I have always eaten.

OMnutritionist helped me to understand that my acne was down to missing essential minerals in my diet that affected the hormones in my monthly cycle. My acne has cleared and so too has my PMS! I am eternally grateful to OMnutritionist as it has solved an issue that I deemed unsolvable, and also given me the confidence and energy that I have always wanted.
