Lose Weight and Transform Your Health As A Result



(...Who Actually Knows What They're Doing)

If you’re here, you may already know that what you eat is an essential aspect of any health and wellness program, because nutritional therapy:

  • Builds resilience to ill health…
  • Empowers the person to take responsibility for their own health…
  • Puts the missing piece of the health jigsaw together…

In other words, working on your diet is the single most neglected and easiest thing you can do for your health.

Nutritional Therapy Helps You With:

  • Weight Challenges

  • Food Allergies

  • Diabetes

  • Digestive Issues

  • Autoimmune Conditions

  • Hormonal Imbalances

  • Detoxification

  • Sports Performance

  • Chronic Pain

  • Fatigue

How It Works

Nutritional Therapy helps you transform your health from feeling like you have no energy, constantly feeling bloated, sluggish and tired. Gone are the days where we teach you about counting calories, the healthy food pyramid or how fats are bad for you. 

We help you uncover the root cause to your health problems by using something called Functional Medicine alongside our nutritional programs. 

Once we get to know you we use the data from the lab reports to teach you how you can overcome your particular health challenge where you will feel and look better. We will even give you a bespoke health and nutrition plan.

You Are What You Eat

What Patient's Are Saying

“My son, aged 3 at the time, was suffering from regular stomach upsets, sickness bugs and had very low immunity. He was missing 1 in every 3-4 weeks of childcare and I wasn’t having much success getting any help via the NHS – the GP wrote it off as ‘one of those stages’ and we were facing a years wait to see a paediatric consultant.  I contacted Clarissa and we soon had our first appointment where we went into great detail around his symptoms and background. At this first appointment, Clarissa set clear objectives and gave us dietary changes and supplement suggestions to support gut health and immunity.  Clarissa supported us until my son was doing a lot better and he continues to have far better health. Thank you Clarissa

Frequently asked questions

about nutritional therapy

Registered Nutritional Therapists work with the client to create nutritional and lifestyle plans that are tailored specifically to their client. It is based on the principle that food provides nutrients that our bodies need in order to maintain a state of wellbeing and balance.

Clients fill in a detailed questionnaire which covers their health history, family history, current symptoms, a diet diary and any medication or supplements being taken.

This information, along with a consultation, is used to create a tailored action plan for the client, since what works for one person may not work for the next.

Nutritional Therapists can also recommend functional testing which can help to identify metabolic, nutritional and other imbalances.

Test results help to create an even more personalised plan by working out the underlying causes of symptoms and thereby to correct imbalances.

Nutritional Therapy is not a one size fits all approach and aims to address nutritional balance for the specific person. It is not a replacement for medical advice. 

Nutritional therapists can help you to lose weight, if you need to lose weight, in a healthy way and maintain a stable, healthy weight.

Often, just by tweaking your diet and lifestyle, weight loss and better skin are a welcome side effect!

By the same token, by looking at the imbalances in a person’s make up, it may be possible to help a person who is underweight to gain weight healthily too.

Not usually. Although our nutritional therapist Clarissa Nolan can take blood as she has experience and specialist training in phlebotomy. 

Registered Nutritional Therapy practitioners have undergone rigorous training so they can help with a variety of issues such digestive issues, detoxification, food allergies and intolerances, weight loss and chronic pain conditions. Our Nutritional Therapist  Clarissa Nolan has a special interest in chronic fatigue, cancer and gut issues. 

Registered Nutritional Therapists are uniquely trained to understand how nutrients, other foods and lifestyle factors influence the function of the body by considering biochemical individuality in a patient centred manner.

Diet and lifestyle can affect how you feel, look, act and think. A poor diet can reduce resilience to infections and stress, slow down concentration and memory. It can lead eventually to poor skin and insulin control, heart disease, digestive problems, memory loss and other chronic conditions.

The number of visits will depend on the individual client and what they wish to achieve. The first two appointments take the longest time as a functional assessment is carried out and those results are fed back. Depending on what the client wishes to achieve, further appointments are then scheduled which usually last from 30 minutes to an hour. These further appointments can take place in clinic or by Skype.
