Patients’ Testimonials

“Olga, your input has been very helpful, as I’ve become more conscious particularly about my diet input which is having a great Impact on my health. I will keep working on it and increasing my physical activities also. Thank you very much for all your help”…

“Olga, I’ve learnt from you about making healthy choices of food, reducing cost and waste as well as maximising time by planning and avoiding frequent trips to the markets. I can definitely feel and sense positive impact from your advice in the short term and long term. Thanks very much for your help”.

“Thank you so much Olga. I am over the moon with my weight loss results and I aim to keep going. All the education, advice and results are really inspiring me on. I’m staring to notice a difference in my body shape too”

“Hey Olga. Just wanted to say thank you so much for your help. Been really enjoying the weight loss I have achieved. I’m currently at 124.3 kg and went down 1 shirt size and 1 trouser size in the last 12 weeks”.

Thanks for the support over the last three months. This has been the only time I’ve ever lost this amount of weight – a stone overall, as I had lost a few pounds before I started to work with you. I want to lose another stone in the next 12 weeks

“Hi Olga. I can’t rate your work highly enough🥇. It has gone above and beyond my expectations and the results are staggering. To know that I haven’t had to skip meals or diet or feel like I’m missing out on certain foods is absolutely amazing. The T plate, traffic light system and fibre after sweet food to lower insulin levels, shopping, eating out and smaller portion sizes are just some of the most helpful tools you have given me. I call them golden nuggets of information. I am so pleased and proud of what you have helped me to achieve and I can’t thank you enough for the support you have given me. I really would like to lose more weight and carry on eating healthy 😊👍 All my friends and family have seen a huge difference in me and how I look. I have noticed my body changing and my taste buds have actually changed as well. All the junk food I thought were my special meals to look forward to, now don’t taste so good. I will look forward to hearing from you on our last session. Thanks again Olga. I really appreciate all the support you have given me. 😊👍

“Olga, I think I did it. I weighed myself this morning and ’ve lost 14lbs while working with you. I am delighted, as I have never lost so much ever! The most I’ve ever lost is about 7lbs. Dance classes start again in a week so that will help again. I’m well on my way to losing 1 1/2 stone in 6 months and I think I could hit my target earlier than that. This is the first time I believe I can do this. I have failed so many times before and it reinforced that you can’t lose weight. Thank you, I think being accountable to you has really helped and although I’ve far from perfect in following the plan it has worked. Now will start the next phase of my weight loss journey. Thanks for all the support over the last 12 weeks. This has been the only time I’ve ever lost this amount – a stone overall as I had lost a few pounds before I started. I want to lose another stone in the next 12 weeks”.
