Client Results & Testimonials

Real People, Real Results

When it comes to health and nutrition, Milena is a real expert and her nutrition and lifestyle advice is easy to follow. She has really helped me keep up a healthy lifestyle while maintaining a very busy life. I feel so much healthier and have more energy.

I’ve been going to Milena with problems with my stomach over the past 4 months. Milena has done wonders for my health, I never felt so much better !!! Still working progress but nothing is done in a short time right !!! Milena knows her job inside and out which I never had from my local doctors or hospitals. Milena has put me on the right road to being normal which I haven’t had in years. I would highly recommend going to see Milena, she’s very easy to talk to and give you confidence to getting better.

Just thought I’d message to say that after my consultation with you around 18 months ago I have since lost 3.5 stone and my testosterone levels are now healthy. Before it was double what it should be. I’ve completely overhauled my whole diet, walk about 15k steps a day which has has stopped all my PCOS symptoms.

Having really struggled with a new Crohn’s diagnosis I felt absolutely at my wits end and completely lost which prompted me to contact Milena. Within two weeks I felt the difference, my chronic fatigue had gone and by the next month I was starting to get back to feeling like my old self. I couldn’t recommend any more for anyone struggling with their IBD!

Milena recently helped me to sort out some ongoing stomach issues which I have suffered from for years, with her help and advice and I’m now feeling better than ever.

I highly recommend it! My daughter has problems with acne, and thanks to Ms. Milena and her recommendations (tests for intolerance, hormonal issues, and deficiencies) and the appropriate supplementation, my daughter’s skin has definitely improved, and her stomach pains have disappeared. Thank you so much—we are both very satisfied and happy. I truly recommend it because Ms. Milena’s knowledge and experience are truly immense and helpful.

I couldn’t recommend Milena more highly! After just 2 sessions, I have been supported to achieve 5 kg of weight loss, shiny and clear skin, control of my binge-eating, improved mood and reduced stress levels. Thanks to Milena’s clear, simple, and tasty recipes and shopping lists, planning and cooking has become easy- with me cooking meals 90% of the time – something I never could have anticipated. I especially love Milena’s Maca balls recipe! Milena’s approach examines and adapts meal plans to make them manageable with a busy lifestyle, developing a plan which I can maintain. Milena has helped me to find strategies to cope with emotional eating, as well as finding creative substitutes for foods I typically overeat to help me better balance my diet. The continuity, feedback and accountability from the bundle of sessions has been invaluable to me, as Milena has adapted my plans to better suit my life with each session. Thank you!!

I suffer from a chronic immune disease. I came to Milena interested in how a change in diet could further improve my symptoms plus my overall health. The advice given by Milena has helped improve my symptoms and also increased my energy throughout the day.

The benefits have been so noticeable that it has been easy to persevere with the changes to my diet.

Nutritionist vs Dietician vs Nutritional Therapist vs Holistic Nutritionist

Understanding the difference between a Nutritionist, Dietician, Nutritional Therapist, and Holistic Nutritionist is essential when you are deciding who to work with.
Although these titles may sound similar, the level of regulation, training, and clinical focus can vary significantly.
By learning how each role differs, you can choose the most appropriate professional to support your individual health goals.

As a clinically trained, Registered Nutritionist and CNHC-Registered Nutritional Therapist in London, I offer personalised nutrition consultations in Mayfair and online.
To explore how I work with clients, you can visit my main page on nutrition consultations in London.

What Is a Nutritionist?

A Nutritionist helps clients achieve better health, energy, and wellbeing through personalised dietary advice.
A qualified Nutritionist may support areas such as weight management, gut health, hormone balance, skin health, sports performance, and general wellness.

However, because the title “Nutritionist” is not protected by law in the UK, anyone can call themselves a Nutritionist, regardless of their training.
Therefore, for your peace of mind, it is important to choose a Nutritionist who is:

  • Clinically trained and degree-educated
  • Experienced in evidence-based practice
  • Registered with a recognised professional body
  • Transparent about their qualifications and approach

As a Registered Nutritionist in London, I provide structured, evidence-based support across a range of health concerns.

You can learn more about my services on my nutrition consultations in London and online nutritionist UK pages.

What Is a Dietician?

A Dietician (also spelled Dietitian) is a nutrition professional who is
statutorily regulated in the UK. Dieticians must meet strict training standards and are regulated by the Health and Care Professions Council (HCPC).

In addition, their main professional body is the British Dietetic Association (BDA).
Dieticians often work within the NHS, hospitals, clinics, and other medical settings.
They are qualified to manage complex medical nutrition therapy, including tube feeding and specialist diets for specific medical conditions.

While Dieticians and Registered Nutritionists both work with food and health, their training routes, regulatory status, and typical workplaces can be different.
Many people choose to work with a Nutritionist or Nutritional Therapist in private practice when they want more time, personalised support, and a functional, root-cause approach.

What Is a Nutritional Therapist?

A Nutritional Therapist uses nutrition to support the body in cases of chronic conditions, functional imbalances, and long-term health issues.
Nutritional Therapy often follows the principles of Functional Medicine, focusing on identifying underlying root causes rather than simply managing symptoms.

Similarly to the title Nutritionist, the title “Nutritional Therapist” is not currently protected by law in the UK.
For that reason, it is vital to ensure that your Nutritional Therapist is properly registered.
For your safety, you should always check that your practitioner is registered with the
Complementary and Natural Healthcare Council (CNHC), the government-backed body established to protect the public.

CNHC-Registered Nutritional Therapists typically:

  • Complete a minimum of three years of rigorous, accredited training
  • Are trained in clinical practice and case management
  • Follow evidence-informed, personalised nutrition approaches
  • Work to high standards of ethics and professional conduct

As a CNHC-Registered Nutritional Therapist and Registered Nutritionist, I was trained in clinical practice and in the principles of Functional Medicine to offer one-to-one personalised health advice. I work with clients from Mayfair, Central London, and worldwide via online consultations.

To learn more about my approach as a Nutritional Therapist, please visit Nutritional Therapist London.

What Is a Holistic Nutritionist?

A Holistic Nutritionist considers the whole person, not just individual symptoms.
This includes looking at nutrition, lifestyle, stress, sleep, emotional wellbeing, and environmental factors to create a comprehensive, whole-body plan.

In practice, Holistic Nutrition often overlaps with Nutritional Therapy and Functional Medicine.
A Holistic Nutritionist may support a wide range of issues, such as low energy, hormone imbalance, poor digestion, skin concerns, and weight issues, using a tailored, root-cause approach.

However, just like the titles Nutritionist and Nutritional Therapist, the title “Holistic Nutritionist” is not legally protected.
Consequently, training and standards can vary greatly.
It is therefore important to work with someone who has accredited education, clinical experience, and recognised registration.

If you are looking for a holistic, personalised approach to your health, you may find it helpful to explore some of my specialist services:

How to Choose the Right Nutrition Professional

When deciding whether to work with a Nutritionist, Dietician, Nutritional Therapist, or Holistic Nutritionist, it is important to look beyond the title.
Instead, focus on their training, registration, and experience with your specific health concerns.

In summary, you may wish to consider:

  • Qualifications – Are they degree-trained or clinically trained?
  • Registration – Are they registered with BANT, CNHC, AfN, HCPC, or another credible body?
  • Specialism – Do they regularly work with your particular issue (for example, gut health, hormones, skin, or weight)?
  • Approach – Do they use evidence-based, personalised nutrition rather than one-size-fits-all plans?

If you are unsure where to start, you may find it helpful to book a consultation to discuss your goals and options in more detail.

If you would like personalised guidance on whether Nutritional Therapy or Nutrition consultations are right for you, I would be happy to discuss your individual needs and goals.

Functional Medicine (Functional Nutrition) vs Holistic Medicine

Functional Medicine (Functional Nutrition) 

Functional Medicine (Functional Nutrition) is a systems-oriented approach aiming to get to the root cause of health issues. It is a science-based healthcare model that is based on the following principles:

  • We are all biochemically individual, based on the concepts of our genetic and environmental uniqueness
  • Patient-centred approach, not the disease-centred approach
  • The factors that influence our health is a complex web of interconnections, not just a cause and effect approach
  • The role of a practitioner is to help the client find dynamic balance between all aspects of their health (body, mind, spirit)
  • The health should be viewed as the presence of positive vitality, and not just the absence of disease
  • Promotion of organ reserve with nutrition

Holistic Medicine / Holistic Nutrition

Holistic medicine is a system of healing that addresses the whole person, not just physical body but also any mental and emotional issues. As a holistic Nutritionist in London, Mayfair, I see every person as individual with different problems and different goals. Taking holistic approach means looking at the whole person. I dig deeper, and I explore all aspects of clients’ health,  on a physiological, physical, and mental/emotional level, to connect the dots between the symptoms and the underlying causes of health issues.

As a holistic Nutritionist I recognise that we are all biochemically unique and what works for one person does not work for another. Each nutrition plan is completely unique. As a holistic Nutritionist in Central London, Mayfair and online, I believe in the healing power of food, however, there is no one nutritional strategy that is right for everyone. Please see the holistic Nutritionist page for more information.

What to expect when you see a Registered Nutritionist in London

A Nutritional Therapist (Nutritionist) works with clients on one-to-one basis conducting assessments of their health, ordering and analysing laboratory testing and writing nutrition plans. Nutritional Therapist (Nutritionist) can support patients with chronic health conditions, as well as clients looking to optimize their health. Holistic in approach, Nutritional Therapist (Nutritionist) will seek to identify and address the root cause of the health, skin or weight issues, with a focus on looking at the whole health picture, understanding that the mind and the body are interconnected.

An initial consultation with a Nutritional Therapist (Nutritionist) normally takes about one hour. During this time the Nutritional Therapist (Nutritionist) will ask questions about the client’s condition and conventional treatment, medical history, diet, and lifestyle. The Nutritional Therapist (Nutritionist) may also perform tongue, face and nail examination to get a better picture of the client’s health. Please see the London Nutrition Consultations page for more information.
