AJ Hazelhurst

About a year ago, AJ saw some photos of himself at a friend’s 50th birthday party, and it was at that moment that he realised he had never looked or felt as bad as he did then. Things needed to change. Under Dr Caryn Zinn's advice, he started Intermittant Fasting. AJ is now 30 kgs lighter. AJ’s ‘aha’ moment was realising that his body simply doesn’t need as much food as he thought it did.
