I have been a personal trainer for 17 years to date. But I learnt so much during this course. I loved each module, plus I shared the knowledge of each one with my clients. During the course, they asked me how I was going. Once I finished it, they were as excited as me. I now have more insight around nutrition, and I feel as confident as ever to deliver the message to my clients to help them with their health journey, whether it be sleep, mindset or nutrition.

I came into this course with a health coaching certification, wanting to deepen my understanding and knowledge of nutrition. I gained so much more knowledge than I was expecting to. So much so, I am now heading in a new direction with my coaching business and focusing on 40s+ health & wellness, covering topics like hormones, energy, mind-body connection, managing stress... all the things that 'fad diets' and 'fasting' are not!

Kaylie Blyton


After living a holistic plant-based lifestyle for over 20 years, I wanted to explore my passion for not only plant-based Nutrition but all the basics needed to explore if this is my true calling. I had only ever studied on campus before, but I found online studies through The Nutrition Institute could fit perfectly into my life. The information was laid out incredibly well, the assignments were great and thought-provoking, and the tutor's feedback was fantastic and so encouraging. I have already convinced a friend to enrol, and they are already loving the journey, too. I have implemented everything I have learnt into my family's life, and I am so grateful to The Nutrition Institute for this.
