How it works

Lewis Gough

Nutrition scientist. Professor. Co-author.

Lewis Gough’s message is simple: supplements only matter once the basics are in place. Match the aid to the demand, dose it with evidence, and rehearse it in training before it counts.

Lewis Gough is a Professor of Nutrition and Physiology at Birmingham City University, where his research focuses on sports nutrition and ergogenic aids for endurance athletes, particularly cyclists. His work examines how supplements like sodium bicarbonate, caffeine, nitrate and beta-alanine actually affect performance.

As co-author of Nutrition and Supplements in Cycling, he translates applied research into practical, evidence-based guidance: which aids are worth using, how to dose and time them, and how to protect gut tolerance so they help rather than hinder.

How does it work?

Connect your wearable or log your sleep, meals and workouts. Each morning Ottavia reads your night and your day, applies Lewis Gough'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 Lewis Gough's subscription?

Lewis Gough'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. Lewis Gough guides and educates through Ottavia, and never diagnoses or prescribes.

Do I talk to Lewis Gough directly?

No. Ottavia has read Lewis Gough'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 Lewis Gough 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.
