In late 2024 a CT scan revealed a small amount of soft plaque in my arteries. Sixteen months later I scanned again, and my plaque volume had dropped by around forty percent. In this episode I ask the cardiologist behind the technology whether a result like that can really be trusted.

Dr Campbell Rogers is an interventional cardiologist, a former Harvard faculty member who ran the cath lab at Brigham and Women's Hospital, and now Chief Medical Officer at Heartflow.

What we cover:

This is a conversation about seeing a disease we used to only guess at, held with the right amount of scientific humility. If you want to understand your own heart health, I think it is well worth your time.

If you enjoy the show, please take a moment to rate and review The Proof on Apple Podcasts or Spotify. It genuinely helps more people find these conversations.

Can a supplement actually reverse the plaque in your arteries, or only slow it down? It is the question I am asked most, and after a 2024 scan revealed early plaque in my own left anterior descending artery, it became a personal one too.

This is part two of my three-part series on reversing atherosclerosis. In this solo episode I work through eight of the most popular supplements and rank them by the strength of the human evidence, not the strength of the marketing.

What we cover:

Only one of these eight has strong evidence behind it, and even then it is a prescription rather than a tub from the supplement aisle. Supplements can be useful additions, but never a replacement for the proven basics.

You can see exactly what I take over at my personal supplement stack.

If you are enjoying the series, the simplest way to help is to leave a quick rating and review on Apple Podcasts, and to share this episode with someone whose heart health you care about.

For decades we have treated the number on the scale as the goal of metabolic health. Dr Mauricio Gonzalez, a triple board-certified physician and endocrinology fellow practising in New York, makes the case that we have been measuring the wrong thing.

In this conversation we explore why liver fat, not body weight, is becoming the real target, what the latest weight-loss medications can and cannot do, and how to cut through the hype and dogma that surround this field.

What we cover:

A grounded, practical conversation with a doctor who meets people where they are. If you enjoy the show, please take a moment to rate and review The Proof on Apple Podcasts or Spotify, it genuinely helps more people find these conversations.

In this episode, exercise physiologist Dr Margie Davenport walks me through what the evidence actually shows about exercise during pregnancy and the postpartum period. Margie chaired the 2019 Canadian Guideline for Physical Activity throughout Pregnancy, the 2025 Canadian postpartum guideline, and the upcoming International Olympic Committee consensus statement on athletes through pregnancy and postpartum.

We cover where the 140 bpm rule came from, the scale of the benefits at the population level, what direct fetal monitoring during HIIT and heavy lifting really shows, the new postpartum data, and why so many of the historical prohibitions do not survive contact with the data.

GLP-1 medications are now part of the mainstream conversation, but the biology of appetite and satiety, the system these drugs operate within, gets far less attention than the drugs themselves. In this episode, I sit down with Dr Federica Amati, Head Nutritionist at ZOE and author of the new book The Appetite Reset, to explore what's actually happening in the gut and brain when appetite signals do their job, and what that means for everyone, on or off medication.

Federica brings a rare combination of pharmacology, clinical nutrition, and public health expertise to a subject that rarely receives this level of nuance. This is a conversation about understanding your biology well enough to work with it.

What we cover:

If this episode was useful, a review on Apple Podcasts or a follow on Spotify makes a genuine difference.

Six years on from our first conversation, global meat consumption is at a record high, and the harms of industrial animal agriculture have only deepened.

Cardiovascular disease is the world's leading killer, and yet the prevention conversation has become noisier and more confused than ever. In this Masterclass I bring together the evidence-first material I think is most useful for understanding cholesterol, blood pressure, and long-term heart health.

You will hear from Dr Walter Willett at Harvard, cardiology dietitian Michelle Routhenstein, and nephrologist Dr Raymond Townsend, alongside my own deep dives on plaque regression, the Portfolio Diet, and six landmark trials.

The earlier you start, the more leverage you have. This Masterclass is meant to give you a clearer map of what actually works.

The peptide and GLP-1 conversation has reached a fever pitch. Growth-hormone-releasing peptides are being marketed as longevity tools, GLP-1s are being treated as a default rather than a last resort, and a wellness aesthetic of higher IGF-1, more muscle, and less fat is being sold as the route to a longer life. In this episode, I sit down with Dr Valter Longo, Professor of Gerontology at USC and Director of the USC Longevity Institute, to look at what the data actually says.

Valter developed the Fasting-Mimicking Diet, has led foundational work on the growth hormone, IGF-1, insulin, and TOR axis across yeast, mice, and humans, and runs non-profit longevity foundation clinics in Europe and the US. He calls himself the anti-biohacker and makes the case using the totality of evidence rather than the loudest claim.
