“I have been working with Kathrin since the end of June - we started by looking at my general nutrition and how to balance my diet to help build my immune system. I then discovered through a visit to the optician that I had cholesterol residues on my retina, so this became a priority for us.

In the space of 2 months, with supplements and diet, my cholesterol levels have improved dramatically, with the subsequent positive effect on my eyesight. I am so thrilled about this, I have signed up for the Sustain programme, so we can continue the great work!

Kathrin is kind, empathetic and an extremely good listener. She makes no judgements and offers sound, rational suggestions that have an impact on your lifestyle as well as your diet. It was really easy to implement the changes and I now have a different outlook towards food and exercise.

I cannot recommend her highly enough!”

— Amanda, Business Advisor

“Kathrin's guidance was invaluable - she listened closely to my concerns and personal situation and created a bespoke package, tackling poor sleep, immune resilience and weight loss for toning without losing muscle mass.

Within weeks I was sleeping better, fighting off illnesses quicker and I now have the knowledge of how to increase muscle definition whilst powering my workouts.

She provides accessible guidance which is easy to incorporate into a busy life, with lots of tips of how to adapt meal plans for family life.

I highly recommend her!”

- Dominique De-Light, Well-Balanced Coaching

“I contacted Kathrin and signed up to her 'Boost' programme because I was in a complete diet-induced mess. I had been trying to lose weight - with some success - but had some awfully unhealthy eating (and not-eating!) habits that were going to do harm long term. A high cholesterol test was the crunch point, and I reached out for help.

The transformation has been nothing short of remarkable. I feel like I've had 3 months of therapy as well as nutritional advice. I very quickly began to realise my relationship with food as a nourishing source of joy was broken, and I'd been so filled with different diet information over my 53 years that my brain was scrambled.

Kathrin took me step by step through a process of thinking, and realising, some key goals. Together (and it did feel very much like she was there every step of the way) I succeeded in changing my eating habits beyond recognition. We focussed on weight loss (a bit), cholesterol (a bit), and fitness (a bit) but they all came together in just making sure that what I eat is nutrient-dense and good for the body, the gut, the mind...EVERYTHING!

I have begun to eat foods I have always disliked, and now love them (it's witchcraft, I tell you!). I cook from scratch - hardly any UPF any more - and am no longer scared of healthy fats or even the odd treat - just balance it all out with a bit of kimchi and a salad and I suddenly feel amazing.

So many friends and family have commented on how glowing I look. That may be the weight loss, or it might be the goodness I'm putting into my body every meal, or it just might be my mood. All in all, this was one of the most profound experiences of my adult life.

Thank you, Kathrin - Optimal Nutrition is a gamechanger.”

— Anne-Mari, Charity Finance Director

“Working with Optimal Nutrition was as fascinating as it was helpful. In my case, there were several issues to overcome, each seeming to complicate the other. Despite this, Kathrin's simple approach led to almost immediate improvement through manageable and proportionate steps that tackled the most significant problems first.

The plan developed to trial new measures while building on the success of previous stages.

The initial impact was amazing, and subsequent improvements significant.

I learned so much from my time with Optimal Nutrition that I will use for the rest of my life, and I can't measure or adequately explain the difference this will make.

Kathrin is realistic and understands how to work with busy lifestyles, and your diet doesn't become boring, much the opposite. I strongly recommend undertaking your own plan, your investment will seem incredible value when you feel the difference it can make.”

— Rob, Head of Retail

“Kathrin is an absolute joy to work with. She ‘gets it’! She’s kind, compassionate and really takes the time to listen and uncover where you need help.

She has been immeasurably supportive to me and my family, providing timely and easy to follow guidance. I’m so grateful for all her support!

— Amanda, Freelance Trainer & Facilitator

“I met Kathrin towards the end of last year, and she helped me to start on a Nutrition programme. I had lost interest in food, within the first few days Kathrin was able to restore this with some great ideas and things I had never tried before. Kathrin took a great deal of time with me to understand my health, circumstances and me - then the programme she designed was set to meet my needs.

I have enjoyed working with Kathrin over the past few months - so much so that I am going to carry on with her further, she has an excellent sense of humour, is knowledgeable, understanding, patient & motivating.

When I first started with Kathrin I was suffering poor health & was always tired, with Kathrin's help my health & sleep have improved and I am back to enjoying eating & cooking again.

Thank you Kathrin, I look forward to continuing the journey.”

— Jill, Retired

“Working with Kathrin on the Boost programme has been part of making significant lifestyle changes following my diagnosis for MS. I can't fully explain what a profound difference her expertise, guidance and recommendations have made for me: increasing and maintaining consistent energy levels, improving my gut health and preparing my body to best deal with any possible medications to come, as well as discovering foods I had never heard of.

I found the nutritional changes Kathrin supported me to make, manageable and surprisingly enjoyable.

I feel better educated about nutrition and its effects, both positive and negative, on my body, and Kathrin answered any questions that came to mind, no matter how bizarre.

I really appreciated the simplicity and clarity of Kathrin's approach and communication, and how she was able to incorporate my reality of also feeding a fussy family and needing minimal stress around food preparation.

Kathrin took particular interest in my medical situation and her detailed research and summaries of the confusing variety of available 'special diets', was really helpful, as was her signposting to good supplements and recipes.

I highly recommend Kathrin's services, dedication and smiley face.”

— Sarah, Freelance Proofreader & Mum of 4

“I highly recommend Kathrin and her nutritionist services! Kathrin was recommended to me; however, I approached with a certain degree of ‘’scepticism’’. How wrong - her advice, approach and guidance have been invaluable in helping me improve my health and well-being.

With her expertise and personalised approach, I've experienced positive changes in my diet and lifestyle. Her support and knowledge have empowered me to make better choices and subtle changes without it appearing that I am giving up all the things that I enjoy but, rather a readjustment.

I am grateful for her exceptional service and highly recommend her to anyone seeking professional nutrition guidance. A satisfied and reformed eater!

- Brin, Consulting Director

“I saw Kathrin for my menopause symptoms and overwhelming tiredness. She was very professional and easy to talk to. She spent time discussing my health and symptoms and suggested some testing to identify vitamin deficiencies.

Her advice and recommendations have meant my symptoms and tiredness have improved. Would highly recommend.”

— Caroline, European People Director

“I really enjoyed meeting Kathrin and she made it very easy to chat through my health issues. She also gave me some sound information and tools that gave me the ability to resolve them and get my energy levels back to normal.”
