The term "ultra-processed food" appeared nearly 100 times in the White House's Make America Healthy Again report. But what if the concept is too imprecise to guide real policy—and could even cause harm?

Dr. David Ludwig—Harvard endocrinologist, obesity researcher, and author of Always Hungry—joins Dr. Dominic D'Agostino to dismantle the ultra-processed food framework from the inside out. Ludwig reveals why the NOVA classification system lumps protein bars with soda, why the FDA admitted they can't define what they're trying to regulate, and why the famous studies showing ultra-processed foods cause overeating may be fundamentally flawed.

This conversation cuts through the noise to identify what actually matters: the mechanistic difference between processing carbohydrates, fats, and proteins—and why that distinction should reshape nutrition policy.

Questions answered in this episode:

• Can ultra-processed foods be "fixed" through reformulation?
• What's the most overrated "healthy" food in supermarkets?
• Should omega-3 levels be part of standard blood work?
• Are GLP-1 drugs a metabolic reset or a lifelong crutch?
• If you could pass one food policy law, what would it be?
• Why did the low-fat diet era make obesity worse?

Dr. Ludwig argues that "ultra-processed food" is a compelling marketing term without mechanistic grounding—and that precise, actionable targets like highly processed carbohydrates and demonstrably harmful additives would do far more to improve public health.

Glioblastoma has a long-term survival rate under 1% at ten years. After decades of research focusing primarily on mutation-targeted therapies, median survival has improved by only a few months. Dr. Tomás Duraj believes there's a better path forward.

Dr. Duraj is a physician-scientist at Boston College working on the metabolic vulnerabilities of cancer. In this Metabolic Health Summit presentation, he outlines a clinical framework for studying ketogenic metabolic therapy — one built on biomarker-driven protocols, not dietary guesswork.

The core argument: cancer cells depend on specific metabolic pathways for survival. Block those pathways while providing alternative fuels to healthy cells, and you create a therapeutic window that most tumors can't escape.

• Why cancer cells metabolically resemble organisms from 2 billion years ago
• The limits of the somatic mutation theory and why most targeted gene therapies have underdelivered
• Substrate level phosphorylation vs. oxidative phosphorylation — and why the distinction matters
• The Glucose-Ketone Index as a measurable, actionable biomarker
• The press-pulse strategy: sustained metabolic pressure paired with targeted interventions
• How to protect healthy tissue before targeting tumor metabolism
• Repurposed pharmacological approaches and the need for publicly funded clinical trials
• The case for small, non-randomized pilot studies with highly motivated patients

Metabolic therapy represents the future of medicine: a coherent clinical strategy grounded in decades of research and increasingly recognized by physicians and scientists across disciplines. For practitioners seeking complementary approaches that extend the reach of oncological therapeutics, this presentation lays out a practical roadmap for integrating emerging insights with standard care.

After 20+ years treating cancer patients, Dr. Christie Kesslering started asking a question her colleagues weren't asking: why are so many of my breast cancer patients metabolically sick — even when they're not obese?

That question changed everything.

Dr. Kesslering is a classically-trained radiation oncologist, metabolic health practitioner, and terrain theorist. She spent two decades practicing oncology in the Chicagoland area before transitioning to focus full-time on what she believes is the missing piece in cancer care: mitochondrial health, and metabolic dysfunction. She now works with cancer patients and chronic disease clients through a telehealth practice built on comprehensive lab work, real-food nutrition, and terrain-based principles.

Questions Answered in This Episode:

• What is mitochondrial dysfunction and how does it relate to cancer?
• Are processed foods, seed oils, and glyphosate implicated in rising cancer rates?
• Can fasting or ketogenic diets reduce chemotherapy side effects?
• What's the difference between cachexia and healthy fat loss in cancer patients?
• How do you identify which foods are problematic for your body specifically?
• What does Dr. Kesslering believe has the biggest impact on cancer outcomes?

A rare look at what happens when a passionate physician follows the data wherever it leads — and why she believes the future of cancer care starts with metabolism.
