About me

One of the most important lifestyle factors affecting your general health and risk for developing certain diseases, is nutrition.

Humans are complicated. You’ll have heard the ‘one size doesn’t fit all’ adage? Well, it’s true for food choices too. Our responses to the same foods can be pretty individual. Personalised nutrition aims to unpick your personal nutritional status and responses, with your optimum health being the end result.

I offer support for a number of diet and lifestyle related conditions such as weight management, hormonal imbalance, thyroid (specifically Hashimoto's thyroiditis), certain autoimmune conditions and gut problems.

In addition, for those just wanting to find out how to safeguard their health into the future, I can help you explore how variations in your DNA and your microbiome can affect your health, weight, fitness and hormonal response with personalised nutrition advice from a friendly and experienced Registered Nutritionist.

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the nutritionist to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.
