Client Results

  • How much does it cost to see a nutritionist in London?
    My prices vary depending on your challenge, and I have different packages available to suit your needs. Prices start from £149.
  • How will you help me reach my goal?
    I will work with you to fully understand your challenge, preferences, lifestyle and motivation for change. Then, using this information, I devise a strategic plan, paired with a meal plan implemented via my app, paired with regular communication (bi-weekly calls, regular text messages and emails) to support you with implementing the plan. Each time we meet, we will amend the plan to keep your diet varied and support you with long term behavior change, beyond working with me.
  • Why is blood and metabolic testing useful?
    By measuring your physiology I can target specific areas of nutrition, exercise and lifestyle to expedite your results so that you reach your goal quicker, whilst improving your health along the way.
  • Why are you different to other Nutritionists in London?
    I have over 13 years of experience as a nutritionist, physiologist and lifestyle specialist, and I am extremely qualified to support you with change. I studied for over 10 years, earning 3 degrees, one of which a PhD. I am trusted by some of London's leading brands, such as the prestigious Kx members club in Chelsea, Dabbs Fitness Mayfair, Myoset, Ten Health and have been accepted into the prestigious UNTIL community.
  • What is your onboarding process?
    Before initiating work with any client, we have a free, no commitment discovery call where we discuss your challenge, needs and goals, and to ensure we are the right fit for eachother. I look for people who are motivated to change and are commited to the process due to limited spaces each month. Then, I ask clients to complete a three day food diary which is analysed using specialist software, before filling out a pre-consultation questionnaire.
  • What happens after our consultation?
    Once we meet, I will then reflect and think about how to achieve maximum results, hyper-personalised to you. Then, I create a strategic plan, and meal plan (housed in my app) which is aligned to your preferences, goals, lifestyle and goals. Free of charge, we then have a call to talk through your plan to ensure you are fully aligned on what needs to be done (changes can be made at this stage if you are unsure on any meals). We then speak bi-weekly either F2F or virtually to support implementation, track progress and ensure the plan is working. The plan is amended every time we meet to ensure you have variety in your diet.
  • Who do you work with?
    I work with a range of individuals, from celebrities, elite athletes, CEOs and the general population. I have a range of expertise from performance nutrition, weight management, gut health, aging, diabetes, energy levels, auto-immune disease and health related conditions. Get in touch to find out more!
  • Can a nutritionist help you lose weight?
    Yes. Nutrition is 100% of your day whilst exercise is just a small fraction. The foods you eat are the key to creating a sustainable weight loss programme. I go beyond the calorie, because calories in vs calories out is now old news according to the science. I will help you to create a nutritional strategy which you enjoy, and gets results!
