December 3, 2024 article from BBC News.
As reported by the BBC, Bartlett’s podcast “is amplifying harmful health misinformation on his number-one ranked podcast.”
His recent controversial shows include Dr. Thomas Seyfried (recently featured by BSI) advocating Cancer as a Metabolic Disease, and Dr. Aseem Malhotra for warning about the risks of the Covid vaccine and other medications.

Metabolic health, medical education, and the case for bringing clinicians and coaches together
At the 2026 Unbreakable Health Retreat in Miami, Emily Kaplan hosted a panel with Bob Kaplan, Professor Thomas Seyfried, and Dr. Derek Lee on what it means to treat cancer as a metabolic disease. They discussed the glucose-ketone index (GKI), nutritional ketosis, and strategies aimed at restricting the fuels cancer cells depend on while considering how metabolic therapy can fit alongside standard cancer treatment.
The conversation also addressed the practical realities patients face when trying to pursue a metabolic approach within the conventional oncology system, including questions about nutrition, repurposed drugs, inherited cancer risk, and how to evaluate different treatment options. Seyfried and Lee connected these clinical questions back to mitochondrial dysfunction, fermentation, and the metabolic vulnerabilities that may offer additional targets for cancer treatment.

At the 2026 Unbreakable Health Retreat in Miami, Professor Thomas Seyfried presented the case that cancer is fundamentally a mitochondrial metabolic disease rather than primarily a genetic one. He contrasts the dominant somatic mutation theory with a metabolic model in which impaired mitochondrial respiration drives a shift toward fermentation, dysregulated cell growth, and the mutations commonly associated with cancer.
Citing the work of Otto Warburg and research from his lab at Boston College, Seyfried explains how cancer cells rely heavily on fermentable fuels—particularly glucose and glutamine—and why mitochondrial dysfunction sits upstream of many of the genetic abnormalities seen in tumors. He also discusses reactive oxygen species, altered cellular signaling, and the role of mitochondria in regulating cell growth and behavior.
The presentation then turns to the therapeutic implications of this model. Seyfried explains strategies aimed at placing tumor cells under metabolic stress by restricting the fuels they depend on, including ketogenic metabolic therapy and approaches targeting glucose and glutamine. For Seyfried, the therapeutic target follows directly from the biology: restrict the fuels cancer cells depend on, exploit their metabolic weaknesses, and treat mitochondrial dysfunction as the central feature of the disease.

Of course, there wasn’t much of substance in this article apart from a reasonable warning that some products he promotes, he is also an investor in. I will keep that in mind the next time I’m inspired to buy myself a beauty cream.
The criticism of Thomas Seyfried amounted to “Oncologists never recommend limiting foods!”, which I read as confirmation of Seyfried’s point that oncologists are utterly clueless about cancers requiring glucose as a fuel.
If the BBC hadn’t heard of Aseem Malhotra before Covid, maybe it’s because the BBC doesn’t listen to the BBC. They have lovely interviews with him going back to 2016 in which Malhotra discusses his concerns over overprescribing of medicines and underreporting of pharmaceutical harms. Fortunately, the BBC has an ‘expert in public confidence’ on hand to set the record straight on pharmaceuticals!
I wish the BBC and the critics would actually try to understand where Seyfried is coming from. He’s got good reason for the conclusions he is drawing.
