"John delivered a fantastic and original presentation on effectiveness, nutrition and exercise at one of our regular UK employee lunches.  It was one of the best-attended sessions we have held, and the feedback was overwhelmingly positive.  His style is amusing and engaging, whilst he challenges many of the 'usual' opinions around healthy eating and living.  I would strongly recommend his talks to anyone who has the chance to book or attend one.  The presentations would work well on company off-sites, team days or additions to board meetings and we are looking at all of these forums to let others hear his important messages."

"Dr Briffa delivered an outstanding session to a senior team of over 150 IBM management consultants at our annual vision and strategy event. He more than lived up to his reputation for delivering insightful, thought-provoking and lifestyle-changing health and nutrition advice to senior corporate staff. His rapid, lucid delivery, combined with his deeply-researched insights, made his session the most popular elective session of the day, with many participants talking long after the event about the impact it had made on their lifestyle."

Managing Director, The Glass Lift

"Dr Briffa spoke on diet and general health tips for nearly 3 hours at our conference in Berlin. Against all odds, he kept a mixed and demanding audience of around 120 people totally engaged: his energetic and humorous delivery style demands attention. Even more impressively, our delegates walked away buzzing with new ideas about how to improve their health and still refer to the session over a year later – a highly memorable morning."

Matthew Gwyther
Editor, Management Today

"John's inspiring session on improving performance in the workplace both entertained and informed our Glass Lift members and NHS guests. It was extremely thought provoking and resulted in a fantastic interactive discussion afterwards. Not only did our members find it enjoyable on the evening but many have since made real differences to their behaviour: what and when they eat & drink, how long they sleep, and other simple things to improve the way they feel and perform at work. Highly recommended for both organisations and individuals!" 

"John Briffa is a total one off. A quite short, dark doctor with an interesting Professor Brainstorm haircut who goes on stage at our conferences and then knocks them dead with his unique blend of science, common sense and humour. He scores right at the top on speaker feedback, and senior businessmen have been known to act on and benefit from his advice long after hearing him."

Ian Bolger

"In an industry populated with individuals with 'brochure knowledge' of health and nutrition, Dr John Briffa was a breath of fresh air in giving us an insight into how to improve our health, wellness and vitality."


"A session given by somebody with impeccable qualifications in the subject. The session was very relevant in relation to our role moving forward both personally and commercially".

"Dr John's experience and knowledge are fabulous in all kinds of fields: healthy eating, sports, sleep, psychological matters and his advice is awesome. Thank you, John!"

"Entertaining with the right mix of evidence-based explanation and simple advice and messages."

"I found it a really interesting and enjoyable session. Dr Briffa made it clear that a few simple changes could make a big impact, and I was inspired to follow his suggestions."

"The mix of scientifically-based explanations and practical, everyday advice worked perfectly for me. I started with diet and sleep strategies right away."

"I liked the provocative challenge on generally accepted 'truths', and the fact that we can achieve a better quality of life with some changes in behaviour."

"Absolutely hit the mark and was delivered in a very engaging manner."

"Something fresh, an energy-packed delivery which made us think about things from a new perspective."

"John's preparedness to challenge conventional wisdom with good arguments was a highlight for me."

"Frank and honest about the realities of everyday life."

"Practical and efficient in delivery of information and gave me lots of easy to digest advice that is easy to apply."

"The speed of presentation was great – listened to every word."

"I wish I'd been exposed to this information a decade ago!"

"This programme really reminds you of how important wellbeing is and shows how it impacts productivity and performance."

"Besides scientific explanations, which always work for me, the tips that we got were practical and connected to our reality and lifestyle."

"The coaching session far exceeded my expectations."

"I was amazed at how much ground we covered in the coaching session, and I found the explanations and advice hugely helpful."

"The one-to-one session allowed me to address concerns, thoughts and ideas that might be more difficult to address with someone in the firm."
