Exercise Metabolism Expert
Fuel smarter. Adapt faster.Every session.
John Hawley’s research on exercise metabolism and carbohydrate periodization, applied to your training, your meals and your real week through Ottavia.
John Hawley
Metabolism researcher. Professor. Educator.
Train low, compete high: place low-carbohydrate sessions where they drive adaptation, and fully fuel the sessions where performance matters.
John Hawley is a Research Professor and Director of the Exercise & Nutrition Research Program at the Mary MacKillop Institute for Health Research, Australian Catholic University, in Melbourne. He is among the most-cited researchers in exercise metabolism, known for his work on fuel use, fat oxidation, and how nutrition shapes training adaptation.
He is best known as a pioneer of carbohydrate periodization, the "train low, compete high" model: deliberately training some sessions with low carbohydrate availability to amplify the body's adaptation, while quality sessions and competition are fully fuelled. Through Ottavia, that thinking is applied to your own training and meals, always with attribution.

How does it work?
Connect your wearable or log your sleep, meals and workouts. Each morning Ottavia reads your night and your day, applies John Hawley's methods where they fit, and gives you one clear plan. Ask anything during the day; the answers use your own data.
What do I get with John Hawley's subscription?
John Hawley's published method, applied by Ottavia to your own sleep, training and meals every day. You see where that work shaped a message, every time.
Why can't I get this from ChatGPT?
ChatGPT answers from general knowledge and forgets you between questions. Ottavia reasons from your actual data, every day, and applies a named expert's published method with attribution. It is not advice in general; it is about your own Tuesday.
Is this medical advice?
No. John Hawley guides and educates through Ottavia, and never diagnoses or prescribes.
Do I talk to John Hawley directly?
No. Ottavia has read John Hawley's published work and applies it inside your guidance. Your questions go to Ottavia; that thinking comes back in the answer, attributed.
What happens to my health data?
Your data stays in your Ottavia account and is used only to guide you. The third-party AI services Ottavia uses never learn who you are: they see the health context needed to answer you, never your name or contact details. Your data is never sold, never used to train AI models, and is deleted from those services when you delete your account.
Does John Hawley see my data?
No. Experts contribute their methods to Ottavia; they never see individual users or their data.
Do I need a wearable?
Ottavia works best with Apple Watch, Garmin or Google Health. You can also log sleep, meals and workouts yourself.
What does it cost, and can I cancel?
The price is shown clearly before you subscribe. Manage or cancel anytime in the Experts hub; you keep access until the end of the period you paid for.
