Eat for real change | Dr Joanna McMillan | TEDxMacquarieUniversity
This talk was given at a local TEDx event, produced independently of the TED Conferences. Most of us know we should eat better, but we don't do it. We are increasingly confused over nutrition with so many conflicting views, and we give scarce thought as to how we eat or our relationship with food.

Jo McMillan is a breath of fresh air as an MC. Vibrant, witty, well prepared and totally engaging of the audience attending. As an Ambassador to the Foundation, Jo also successfully conveyed to the audience that the function she MCed was a fundraiser, with funds raised on the evening indicating the measure of her success. We thank her very much for her contribution to the Foundation generally, and as a fabulous MC and speaker at our recent White Night Gala Ball, attended by over 200 guests.
Joanna's advice on how to improve one's personal well-being through sensible exercise and better nutrition was well received by her audience of Rotarians and their partners at the annual conference. Her pleasant and informed approach to the subject was enthralling and she provided vital information with the right mix of humour and examples from her own life experiences. Joanna's delivery was both stimulating and challenging, such that many in the audience planned to make immediate changes to their own life styles in order to achieve more joy in their life. An excellent presentation!
I've seen Dr Joanna speak several times at different events and conferences - both virtually and live in person. Jo ticks every box you'd want in a speaker - she's THE expert in her space; she's super engaging and warm with her audience and she explains things in a way that makes you want to make a change to the way you live. She's also brilliant to work with - on the briefing calls, and on-site with the client, I always enjoy being around her Scottish charm !! ; ) If you're thinking of booking Jo for your event - I can't recommend her highly enough.
Jo is a one-of-a-kind emcee who brings energy, warmth and engagement to every moment. Her vibrant presence and infectious enthusiasm light up any room, and we are incredibly grateful to have had her as part of our Dietitians Unite event for 10 years. With the perfect balance of charisma, authenticity and credibility, Jo connects effortlessly with the audience, captivating and inspiring them. Her seamless transitions and insightful commentary elevate the event, making it unforgettable. I highly recommend Jo for any event seeking a dynamic and memorable experience.
