Coffs Coast Nutrition is the local area’s most trusted nutrition and dietetics practice. Our team provides individualized nutrition, exercise and wellness advice in a supportive, caring and non-judgmental environment - in person and via telehealth (your choice of phone or Zoom / video). Our holistic approach is designed to help you achieve the best possible result. We also offer a greater range of appointment days and times than other nutrition practices in the Coffs Harbour area.

Coffs Coast Nutrition is a small local business. We don't employ physiotherapists, massage therapists or occupational therapists, however we are happy to work alongside other allied health professionals or refer you to the appropriate person. The fact that we are a small business is an advantage. It means that you will receive more personalized attention than if you were to attend a bigger clinic that employs a large number of staff. Our dietitians and personal trainer are also highly qualified and experienced.  

Coffs Coast Nutrition owns an AlterG anti-gravity treadmill which uses state of the art NASA technology to reduce loading during walking and running. This technology is generally only available in major cities (Coffs Coast Nutrition has the only anti-gravity treadmill between Coffs Harbour and the QLD border). The AlterG treadmill is NOT your typical treadmill. It uses differential air pressure to enable pain-free walking or running at 20-100% body weight. This equipment is utilized by people who would otherwise find exercise too painful, however it is also used to enhance sporting performance by top athletes. For more information: click on the 'AlterG' tab (at the top of our home page) and watch the short videos.

Our Nutritionists / Dietitians have appointments available during week days. We also have some weekend and after hours appointments.  In view of COVID-19 our Nutritionists / Dietitians also offer phone / remote video / Zoom consultations. These are very popular due to the convenience (you don't need to leave home or work to have a consult).

Our PT offers one-on-one sessions (by appointment) 7 days per week. You do not need to see our Nutritionists / Dietitians to attend PT sessions (although there are benefits to combining both nutrition and exercise). Outdoor training sessions are available, and depending on COVID-19 restrictions, there is the option of using our private studio gym in a COVID-safe environment where it will be just you and our trainer. 

We have implemented strict hygiene standards with both staff and clients. Please read the sign on our door before entering and follow all instructions. If you or a family member are unwell you MUST reschedule your appointment. Alternatively we can arrange a phone or Zoom consultation at the same day and time so that you can have your consultation from the comfort of your home. 

You MUST have your mask fitted correctly prior to entering our premises. This means that it should cover both your mouth and nose.

IRRITABLE BOWEL SYNDROME (IBS), functional gut disorders, bacterial overgrowth, gastric motility issues and endometriosis are specialties, with many clients achieving life-changing results.

Lots of nutritionists and dietitians provide advice re IBS, however this is a specialised area, so if you want the best possible results it is important to see someone who specialises in this area and has BOTH professional and personal experience in gastrointestinal conditions. 

Louise is the most experienced and qualified IBS and FODMAP dietary specialist on the Coffs Coast. She has completed several courses through Monash University regarding the treatment and diagnosis of IBS, as well as implementation of the low FODMAP diet and has also attended numerous other IBS courses and seminars which enables her to provide the most up-to-date information. Louise understands the importance of listening to what people have to say, rather than simply providing generic informationThere is so much more to IBS and gut issues than simply completing a course and providing a handout!

Louise has extensive experience with the RPAH elimination diet and can also discuss other medical conditions that you may not be aware of which sometimes mimic IBS and need to be ruled out. 

Other interests include anti-inflammatory nutrition, the gut microbiome and the link between dysbiosis and mood disorders such as anxiety and depression, autoimmune conditions,  inflammatory bowel conditions, chronic fatigue, weight management, diabetes, heart disease, sporting performance etc. If you are interested in gut health, we can refer you for microbiome testing.  

Louise has an interest in weight management and has motivated countless people to lose weight and keep it off. Her research into weight loss and fad diets was published in a scientific journal and received widespread media exposure. She puts a strong emphasis on health and wellbeing, intuitive eating and establishing a positive body image.

Louise has also supported people who have undergone BARIATRIC SURGERY for over 16 yearsto ensure that they achieve the best possible outcome from their surgery. 

Louise is the most experienced ACCREDITED SPORTS DIETITIAN on the Coffs Coast. She has also completed the Level 1 Triathlon Coaching Course and Level 2 Coaching Principles through the NSW Academy of Sport, in addition to her personal training qualifications. She has undergone additional training through Monash University involving exercise-induced gastrointestinal syndrome in athletes.  

Louise has had the privilege of providing sports nutrition advice to athletes around Australia, from a variety of different sports. Prior to injuring her back Louise competed in triathlons, in events ranging from sprint (500m swim, 20k bike, 5k run) to Ironman (3.8k swim, 180k bike, 42.2k run). An in-depth knowledge of sports nutrition played a big part in her numerous wins and placings during her time in the sport.  

Louise enjoys the relaxed lifestyle that comes with living on the beautiful Coffs Coast, and although no longer able to compete in triathlons due to injury, she keeps fit by training with her husband Col, and running on Coffs Coast Nutrition's AlterG anti-gravity treadmill. She also loves to go for leisurely walks along the beach.
