Cancer, Circadian Biology, and the Questions Nobody Asked | Jeffrey Hartford | EWP
07/10/2026 | 58 mins.Sarah Kliner welcomes Jeffrey to the Evolving Wellness podcast to discuss his experience navigating a left-kidney tumor diagnosis (clear cell renal cell carcinoma) using circadian and quantum biology principles, deuterium depletion, and lifestyle changes rather than standard-of-care surgery that would have removed his entire kidney. Jeffrey connects his health journey to long-term emotional suppression, alcohol use, and late nights under artificial light, describing the diagnosis as a catalyst to set boundaries, align with authenticity, and trust intuition. He shares practices including consistent sleep aligned to light-dark cycles (using the My Circadian app), cold plunging (Morasko), red light therapy (Soleil Well), sauna, local seasonal whole foods, minerals, and deuterium-depleted water, while reducing supplements and discontinuing an ivermectin/mebendazole protocol. He reports some scans showing shrinkage and aims to empower others to make changes before a diagnosis.

Low ferritin is one of the most overlooked root causes of feeling cold all the time, restlessness, and chronic fatigue - and "just taking iron" isn't the answer. In Episode 1, Sarah Kleiner shares her personal journey with low ferritin, why standard iron advice fails, and what actually moved the needle for her.
She breaks down the connection between gut health and ferritin levels, why you can't just supplement iron without addressing absorption, the role of stomach acid (HCL) in iron uptake, how estrogen clearance is tied to iron status, and her 90-day testing protocol for tracking ferritin. If you've been told your ferritin is "normal" but you still feel terrible, this episode is for you.

30/09/2026 | 51 mins.Sarah Kleiner welcomes Dr. Anna Cabeca to discuss perimenopause/menopause support for hormone-hesitant listeners, hormone users, and those wanting non-hormonal approaches. Cabeca emphasizes “it takes more than hormones to fix your hormones,” advocating foundations like circadian and lifestyle factors, detoxification pathways, gut and mitochondrial health, and working with individual physiology rather than one-size-fits-all hormone protocols; she frames treatment as hormone “replenishment” and notes benefits of progesterone, pregnenolone, DHEA, and sometimes estrogen/testosterone depending on metabolism and clearance. They discuss increased post-pandemic inflammation and autoimmune issues (Hashimoto’s, dysbiosis), rising MCAS/histamine intolerance linked to estrogen fluctuations or impaired estrogen clearance, and practical supports including food/stress diaries, oxytocin-boosting practices, daily bowel movements, and drainage/lymph strategies. They also cover keto/carnivore drawbacks for some women (uric acid, weight gain), thyroid markers like reverse T3, ferritin optimization, and the importance of individualized, terrain-focused care. Cabeca shares where to find her work and programs

I share the exact nutritional strategy I used to triple my ferritin and regulate my full iron panel in 90 days - without relying on iron supplements alone. If you're struggling with low ferritin, iron dysregulation, or chronic undereating patterns that are elevating your hepcidin, this video walks you through everything I changed in my diet.
You'll learn why carb restriction raises hepcidin, why heme iron beats non-heme sources, how resistant starches support estrogen clearance, and how eating three warm cooked meals a day (including congee!) helped me rebuild my blood.

23/09/2026 | 1h 1 mins.Sarah Kleiner welcomes Dr. Amie to discuss why many people with hypothyroid symptoms are dismissed after only TSH (and sometimes T4) testing and placed on T4-only medication without improvement. Dr. Amie shares her own journey through multiple doctors before being diagnosed, learning that T4 must convert to active T3, and ultimately finding functional medicine support with more thorough testing and individualized treatment. They discuss tailoring thyroid hormone replacement, how low ferritin and stress can affect tolerance to T3, and how long-term carnivore/ketosis may lower free T3 for some people. They cover thyroid’s links to metabolism, temperature regulation, mood, and long-term risks, address misconceptions about T4 and cancer via reverse T3, and emphasize getting a full thyroid panel and not accepting dismissal. Dr. Amie shares resources, including a quiz at dramy.com/quiz
