About the expert

Focus: Argues that alcohol is a poison with no safe intake level, and that most people cannot judge their own drinking because it is normalised inside their friendship group. Uses biomarkers and wearable sleep data to make the harm visible, and recommends a three-month alcohol holiday as an experiment rather than a verdict.

Ula Heywood is an emergency medicine specialist (MBChB, FACEM) who spent around 15 years as an ED consultant before founding Autonomy Health in Auckland in 2021, a private preventive and precision health clinic. She works with patients over months rather than minutes, building a baseline from over 100 biomarkers and revisiting it at three, six and twelve month intervals. She describes herself as a storyteller rather than a doctor, and calls herself Dr Killjoy when the subject turns to alcohol. Her clinic sells the biomarker panels and genetic testing this episode recommends. This does not invalidate the physiology she describes, and the two are worth judging separately. It is still worth knowing that the person telling you to measure your baseline also sells the panel that measures it.

Expert discussions with Dr Ula Heywood

Should you try three months without alcohol?
Alcohol is a poison your body converts into a worse one, and the harm is real at doses most people consider normal. This conversation is unusually good on why, and it ends by recommending a three-month break. That specific number has no evidence behind it, and it happens to be the length of the programme the host sells. The experiment is still worth running. Just measure how you feel rather than counting to ninety.
