Functional Nutrition

Have you ever received good advice that you were unable to follow? Has your doctor ever recommended a lifestyle change that you found to be unsustainable? Have you ever wanted something in your life, but found you couldn’t achieve it alone? Are you fed-up with doctors just prescribing pharmaceutical medicine?

Is function nutrition or nutritional therapy for you?

Functional Nutrition is an evidence-based approach to maximising one’s health potential though individually formulated nutritional and lifestyle changes. Functional Nutrition uses the principles of Functional Medicine.

What is a FM approach?

Functional Medicine seeks to identify and address the root causes of disease, and views the body as one integrated system, not a collection of independent organs divided up by medical specialties. It works on the whole system, not just the symptoms. Functional medicine creates a focus on prevention through nutrition, diet, and exercise; use of the latest laboratory testing and other diagnostic techniques; and prescribed combinations of drugs and/or botanical medicines, supplements, therapeutic diets, detoxification programs, or stress-management techniques.

Its health problems that plague modern society result from weaknesses in the body’s physiological foundations as a result of poor nutrition. As a functional nutritionist, I help individuals and healthcare professionals understand and reverse the tragic and unsuspected effects of the modern diet & lifestyle on clients based on their bio-individual nutritional needs.

Functional Nutrition teaches the concept of bio-individuality. There is no perfect diet for everyone. Functional Nutritionists are trained to help each client find the right types of whole foods that will restore balance and enhance their ability to heal. Therapists may work with clients who have chronic health problems that conventional medicine may find difficult to treat or with individuals who are interested in improving their health through diet, supplements & lifestyle.

Functional Nutrition is never used to manage acute or life threatening conditions. Functional Nutritionist are well-equipped to provide medium to long term support to those suffering with a pre- or diagnosed chronic condition & who seeks a more holistic natural approach to healing & better health.

What my clients say:

“I’ve always been a ‘big’ girl but in my school years I played hockey and semi kept my weight in check. Since leaving school, living in the bush, with no gym around I have just let myself go!! I had tried different diets and exercise programmes and nothing worked. In my 30th year, I made a decision that something needed to be done. I needed someone who wasn’t family or close friends to be accountable to and someone that I paid, so i knew i would stick to it. I also do not live close to a gym, so it needs to be something I could do at home. I found out about Ilse through a friend and the way she was described was a wife and mother and down to earth. WOW, I can only describe Ilse as Wonder Woman!! Since I’ve been working with Ilse, she has made many positive changes in my mindset towards exercise, food and lifestyle. She explained that its not a diet and is not going to be temporary….it’s need to be a lifestyle change, and that put everything into perspective. It has been wonderful to know that Ilse is just a text away and knowing that we have scheduled monthly meetings, makes me want to push myself harder. The constant support, through texts, emails and messages from Ilse most definitely keeps me going. What I found most wonderful is Ilse made the programme specifically for me according to the foods which I do/don’t like and exercises which I do/don’t like. It most definitely hasn’t been plain sailing all the way, but when I’m having a wobbly, Ilse has been there to put me back on track. For a life changing experience in more way than one, I would undoubtedly recommend Ilse!!

“ Ilse is the most knowledgeable and caring functional nutritionist that I have met. She is very passionate about her work and about helping other live healthier lives. Not only does she takes a long time understanding each one’s lifestyle and health concerns, but she also provides detailed recommendations adapted to what is feasible for each one. Changing a lifestyle that you have been living for years is not easy, hence the importance of being supported by someone that understands that and is patient to help you get through the changes one step at a time. She is also very patient and a lovely person, I can’t recommend her enough!! Thank you SO much for everything you’ve done for me and my family, Ilse!! I’m forever grateful!”
