Good health is your most priceless asset

Perfect Human Food  focusses on the upstream causes of chronic disease, rather than just addressing the symptoms. Not surprisingly, when the lifestyle is improved sufficiently, the body can heal and vibrant good health can be restored.

Adopting healthy nutrition and lifestyle can be truly life-changing.
Your good health is your most priceless asset. Most people don't appreciate the value of their health until they lose it.
I have helped many people lose weight, lower cholesterol and blood pressure, reverse their type 2 diabetes, arrest and improve auto-immune conditions and to solve their gut problems.
I specialise in plant-based nutrition but will help you wherever you are at to get to your health goals, whatever they may be.

Peer-reviewed research has shown since 1990 how to reverse our biggest killer - cardiovascular disease. Evidence has existed for reversing Type 2 diabetes since the 1940’s.

Dr Peter Johnston
Accredited Practising Dietitian, Lifstyle Medicine Practitioner, BA, BSc (Hons), MSc, PhD, FASLM.

Dr Peter Johnston is a Melbourne-based accredited practising dietitian, lifestyle medicine practitioner and qualified health coach. My passion is to offer individuals and groups the opportunity to learn how to prevent, arrest and reverse chronic disease through evidence-based nutrition and other healthy lifestyle choices.
An analogy is: if you put the wrong fuel in your car it won’t end well! It is no different for us humans. A single human cell is more sophisticated than the most expensive car you could buy! Yet most of us are not fully aware of the powerful impact that diet and lifestyle have on our wellbeing. My mission is to give you the knowledge and skills to heal yourself (or stay well) with perfect human food – a Whole Food Plant Based lifestyle. Or to help you improve your diet and lifestyle to whatever extent you are ready to embrace.
It is an enormous privilege and joy to help patients get well and stay well. Improving your diet and lifestyle can be truly life-changing!

The power of optimal nutrition
and a healthy lifestyle

Our healthcare system is bursting at the seams with people burdened by chronic disease and/or obesity. Lifestyle medicine programs (which focus on nutrition, exercise, sleep, stress, addictions and social connections) address upstream causes and are the best way to treat and often reverse these conditions - and are highly cost effective. My colleagues and I are offering a range of different group programs starting at under $1000/patient, successfully diverting most participants from expensive surgery and a lifetime of drugs. Compare that to up to $50,000 per bypass surgery.
