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 offsites, team days or additions to board meetings and we are looking at all of these forums to let others hear his important messages.

Dominic Magee, Director


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.

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.

John spoke at our restructuring awayday. His talk was enlightening, thought-provoking, educational and, of course, humorous. All together this means there is a real chance of changing peoples lives for the better which is ever more important these days.

Neville Kahn

Head of Corporate Finance, Deloitte

PwC is a professional services firm that has enjoyed an association with Dr John Briffa for 17 years. Dr Briffa is the critical instructor on the most successful and enduring development programme in PwC. There is consensus about Dr Briffa in PwC. He has a reputation for offering practical advice in an inspiring way that produces results.

I am convinced that over the years he has helped to re-energise countless individuals, including partners, staff and clients whom I know personally. The passion and the expertise ooze from every session, and so coherent is his universally applicable “big idea” which underpins his advice, that he actually succeeds where the vast majority of consultants fail. That is to say he alters the inner world of many people forever. That is the key to how he can alter their behaviour in a sustainable way.

We are convinced that Dr Briffa’s interventions makes a fantastic difference to the quality of life, productivity and effectiveness of scores of professionals in our business.

David Prosser

Senior Partner PricewaterhouseCoopers

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.

Our most senior executives were particularly energised by his thinking and practical insights and have expressed a keen interest in a follow-up session. Above all, John’s personable warmth and engaging style make him not only a pleasure to listen to, but very easy to work with in shaping the agenda and style of his pitch to suit our audience and programme objectives.

Partner – Human Capital Management – Learning Solutions, IBM Global Business Services

I have worked with Dr. John Briffa for 10 years and have found him to be an extraordinarily intelligent and competent professional in his work with our firm, PricewaterhouseCoopers, in Canada.

John’s knowledge of nutrition and how it impacts on the physiology and psychology of our bodies is robust and is very current in nature. John has an incredible ability to make sense of a complex topic easy to understand for non medically trained individuals

I believe we are exceptionally fortunate as a firm to have been able to work Dr. Briffa over the past 10 yearsand it is my hope that we will have yet another 10 years of his counsel and support in enhancing the nutritional and lifestyle behaviours of our senior partners.

Wayne McFarlane

Former global head of HR, PricewaterhouseCoopers, Canada

John ran a half day seminar on healthy working for our team of 30 multinational Consultants. He is a lively, amusing, provocative and convincing speaker who prompts debate both in the session and long afterwards – we still hear that things are not “Briffa compliant” weeks after the event.

The session covered diet, sleep, exercise, the need for light and effective breathing – all his points are well argued, supported by research results and, ultimately, make intuitive sense. As a resultour people actually seem to use what they learned.
