Food Junkies Podcast
In this episode, Paige and Jamie from Real Food Recovery join us to explore the powerful intersection of holistic health, nervous system regulation, and long-term recovery from ultra-processed food addiction. They share why they wrote their book, the four core branches that anchor recovery, and why recovery isn’t about perfection—it’s about resilience, compassion, and sustainable support systems that hold us when life falls apart. With honesty and courage, Jamie shares her story of leaving an abusive relationship and navigating destabilization while protecting her recovery....

In this episode of the Food Junkies Podcast, Clarissa and Molly sit down with psychologist Dr. Carrie Wilkens to unpack what it really means to help people change without shame, stigma, or power struggles. Drawing from decades of work in substance use, eating disorders, trauma, and family systems, Carrie invites us to rethink “denial,” “relapse,” “codependency,” and even the disease model itself, while still honoring the seriousness of addiction and the depth of people’s pain. Together, we explore how self-compassion, curiosity, and values-based behavior change can transform not...

In this Clinician’s Corner episode, Clarissa and Molly dive into what they lovingly (and accurately) call the “Hella-Days”—that stretch from early fall through New Year’s where routines disappear, food is everywhere, emotions are high, and nervous systems are fried. Together, they unpack why this season is so activating for people with food addiction and nervous system sensitivity, and how to navigate it with values, boundaries, and a whole lot of self-compassion—whether you’re surrounded by family or spending the holidays on your own. In This Episode Clarissa & Molly...

In this episode, we sit down with integrative oncologist and metabolic health pioneer Dr. Nasha Winters (who insists we call her Nasha) to explore the powerful intersection of cancer, ultra-processed foods, metabolism, and sovereignty. Nasha shares her astonishing personal story: years of dismissed symptoms, normalized suffering, and relentless gaslighting that culminated in a diagnosis of end-stage ovarian cancer at age 19—and being sent home to die. Thirty-four years later, she’s very much alive and leading a global movement to rethink cancer as a metabolic, terrain-driven disease rather...

On this episode of the Food Junkies Podcast, we welcome back Dr. Erica LaFata to dive into her groundbreaking work developing the Food Addiction Severity Interview (FASI) — a clinician-administered diagnostic tool modeled after the SCID alcohol use disorder module and adapted for ultra-processed foods. Building on self-report tools like the Yale Food Addiction Scale (YFAS) and mYFAS, Erica explains why the field urgently needs a structured clinical interview to validate ultra-processed food addiction as a distinct psychiatric presentation and move toward formal recognition in the DSM....

In this powerful episode, Dr. Vera Tarman and Clarissa Kennedy welcome back Dr. Nicole Avena, one of the first researchers to scientifically validate the concept of food addiction. Together, they unpack the latest critiques of food addiction and explore why this diagnosis is still being challenged – and why the science strongly supports it. 🔍 Key Questions We Tackled Is food addiction “too broad” to be useful? Can we really rely on self-report tools like the Yale Food Addiction Scale? What about brain imaging – doesn’t Kevin Hall’s PET study “disprove” food addiction? Are...

C J shares a moving conversation with Ashley Elizabeth, a woman whose honesty and courage shine through her recovery journey. Ashley is remarkably open about her experience with food addiction and the lifelong impact of being put on a diet at a very young age. Like so many, she spent years trapped in the cycle of obsession, shame, and the constant search for control, returning to foods she didn’t even like just to get her fix. When Ashley first entered a 12-step program, she approached her food plan like another diet, and for a while, it worked. But true transformation came when she embraced...

Molly and Clarissa get real about the spoken and unspoken “rules” we inherit—from family, culture, religion, peers, and recovery spaces—and how those rules can quietly run our lives. They explore when structure is protective (especially early recovery) and when rigidity shrinks our world. The invitation: notice the rule, name whose voice it is, examine its intention, and rewrite it as a flexible, values-aligned boundary (a loving guardrail) that serves your recovery today. What we cover Invisible operating systems: How covert rules (“Don’t cry in public,” “Finish your plate,”...
info_outlineDr. Vera Tarman sits down with Dr. Bart Kay—former professor of health sciences turned “nutrition science watchdog”—to unpack a big, practical question for people in recovery from ultra-processed food use: If sugar needs to go, what about other carbs? And where does dietary fat fit in? We explore Dr. Kay’s perspective on the Randle (Randall) cycle, insulin resistance, mixed macro diets, seed oils, ketogenic/carnivore patterns, and real-world considerations for folks with sugar/UPF addiction who struggle to “moderate.” We also discuss staged change (don’t flip your diet overnight), what “abstainer vs. moderator” can mean in food recovery, and how to keep any nutrition experiment aligned with your health team and your recovery plan.
What we cover
- The “Randle cycle,” plain-English: why mixing higher carbs and higher fats may worsen metabolic friction, and why choosing one dominant fuel is central to Dr. Kay’s model.
- Insulin resistance re-framed: why Dr. Kay views it as a protective cellular response (his position) and how that informs low-carb/carnivore advocacy.
- Carbs in recovery: “quit sugar” vs. “how low is low?”—Dr. Kay’s thresholds (e.g., ≤50 g/day unlikely to cause problems in his view) and why many with UPF addiction do better with abstinence than moderation.
- Fats & satiety: why dietary fat often increases fullness cues; practical guardrails; “can you eat too much fat or protein?”
- Seed oils: Dr. Kay’s strong critique of industrial seed oils and his inflammation concerns.
- Cholesterol worries on low-carb/carnivore: why lipid numbers may rise and how Dr. Kay interprets A1C and lipid changes (controversial; see note below).
- GLP-1s, metformin & meds: Dr. Kay’s take on drug mechanisms vs. root-cause nutrition changes.
- Change management: why he recommends a 4–6 week ramp instead of an overnight switch to very low-carb/carnivore; supporting thyroid, energy, and the microbiome while you transition.
- Recovery lens: abstainer vs. moderator, harm-reduction steps when “only food will regulate,” and building a plan that supports mental health and addiction recovery.
Key takeaways
- Abstinence can be a kindness. If you’re a “can’t moderate sugar” person, treating sugar/UPFs as an abstinence-worthy trigger can protect your recovery.
- Don’t crash-diet your microbiome. If you’re experimenting with lower-carb or carnivore, step down over 4–6 weeks with plenty of electrolytes, hydration, and support.
- Pick a lane with macros. In Dr. Kay’s model, mixing higher carbs with higher fats is the most metabolically problematic; choosing one dominant fuel source may reduce friction.
- Numbers are data, not destiny. Lipids and A1C can shift on low-carb—interpret changes with a clinician who understands your whole picture (medical history, meds, symptoms, goals).
- Harm-reduction still counts. If full abstinence isn’t feasible today: remove red-light foods first, shrink access, use “pause + plan” tools, and reach out before the binge.
