Dr. Peter McCullough on Alzheimer’s, Cancer—and the Health Questions Dividing America
09/09/2026 | 1h 2 mins.This is StRest! Kerstin Lindquist sits down with Dr. Peter A. McCullough, an internist, cardiologist and epidemiologist, for a wide-ranging conversation about Alzheimer’s risk, cancer detection, obesity, COVID-19, vaccines and the daily choices he believes can protect long-term health. Kerstin begins with a clear disclaimer: several of his positions are controversial, and her goal is to help listeners hear another perspective, ask questions and speak with their own doctors.
Dr. McCullough explains why Alzheimer’s is personal. His father died with the disease, his mother is currently living with it, and he is focused on protecting his own cognition. He discusses body weight, alcohol, outdoor movement, ApoE genetics, newer blood testing and the choices people may make when they better understand their risk.
Kerstin and Dr. McCullough also examine inherited cancer risk, whole-body MRI, blood-based cancer testing and why standard screening such as colonoscopy still matters. The conversation then moves into his views on the pandemic, COVID-19 vaccination, routine childhood vaccination, nasal sprays, gargling and public trust in medicine.
The episode closes with where he finds hope and the health practices he considers non-negotiable: food quality, portion control, aerobic and strength training, time outside, sleep and avoiding alcohol. He also explains why he encourages some patients to try 90 alcohol-free days and observe what happens to their sleep.
MEDICAL NOTE
This episode presents Dr. McCullough’s views for discussion, including positions that are controversial. It is not personal medical advice. Speak with a qualified healthcare professional before changing vaccines, medications, supplements, testing or treatment.

Kerstin Lindquist sits down with beauty entrepreneur Sara Happ for a raw conversation about building the lip-care company that carried her name, losing control of what that name represented, and walking away from the business she created.
Sara shares how a lip scrub she mixed in her kitchen grew into a major beauty brand and led to an eight-year run on QVC. She explains why the QVC set became one of her safest places, what changed after outside investors entered the company, and why she could no longer look customers in the eye and promote products she did not control.
The conversation also turns to Sara’s three-decade battle with endometriosis, her 2023 hysterectomy, and the grief of giving up the possibility of carrying another child. She describes what doctors found during surgery and why women should not dismiss severe pain simply because they have learned to function through it.
Kerstin and Sara also talk about divorce, therapy, family, faith, closed doors, and learning to stop measuring personal worth by revenue, appearance, or performance. Sara shares the two questions that now guide her decisions, why peace became more valuable than a paycheck, and what it means to write a new chapter on her own terms.

Kerstin Lindquist sits down with Liz Roman—better known online as The Poop Queen—for a direct conversation about constipation, bloating, Hashimoto’s, hormones, and what to do when you feel terrible even though your labs are called “normal.”
Liz opens up about being diagnosed with childhood rheumatoid arthritis, struggling with painful periods and chronic constipation, and eventually discovering Hashimoto’s, Giardia, Candida overgrowth, and broader gut dysfunction through functional testing. Her own health journey led her to leave corporate human resources and build a practice focused on helping women understand their symptoms and search for root-cause answers.
Kerstin and Liz break down stool testing, parasites, Candida, elimination diets, and why Liz prefers to support digestion, bowel regularity, hydration, liver function, and nutrient status before using aggressive eradication protocols. They also discuss why adding too much fiber too quickly can make bloating worse—and why the type of fiber matters.
The conversation also connects perimenopause and menopause with constipation, histamine reactions, estrogen clearance, bile flow, liver and gallbladder support, and HRT. Liz shares the lab markers she watches, the supplements she commonly discusses with clients, and why health changes should be guided by data instead of guesswork.

Nancy opens up about leaving QVC after 12 years, handling criticism, chasing purpose instead of money, and learning not to let rejection define her. She also shares why she chose to spend three months completely cut off from her family, phone, internet, news, and social media for Greg Gutfeld’s What Did I Miss?
That experience forced Nancy to confront control, fear, family responsibilities, and her identity outside of being a wife, mother, and caretaker. Surprisingly, she found more peace in isolation than she expected—and more stress when it was time to return to normal life.
Nancy and Kerstin also talk about parenting, faith, political division, postmenopause, and one of Nancy’s biggest lessons from the experience: seek first to understand, then to be understood.

Kerstin Lindquist sits down with Dr. Jen Pfleghaar, a board-certified family nurse practitioner, author of The Perimenopause Reset, and women’s health advocate whose work brings together faith, integrative health, and the realities of midlife. Dr. Jen explains why she believes symptoms such as anxiety, heart palpitations, difficult PMS, weight changes, and disrupted sleep can be signals that something deeper needs attention rather than issues women should simply cover up.
Dr. Jen opens up about her own spiritual journey and how she became deeply involved in yoga, meditation, Reiki, crystals, and other New Age practices while working in integrative medicine. She explains why she ultimately walked away from those practices, returned to Scripture, and began rethinking where she placed her identity as a doctor, mother, and professional.
The conversation turns to family, marriage, and the major changes Dr. Jen made after realizing the stress of running a brick-and-mortar medical practice was affecting her home life. She shares why she closed the practice, moved with her family to a small farm outside Nashville, shifted to virtual care, and began putting greater emphasis on her role as a wife and mother.
Kerstin and Dr. Jen also explore what they describe as spiritual warfare during perimenopause. Dr. Jen explains how changing hormones can leave women experiencing anxiety, isolation, weight gain, emotional changes, and symptoms they may never have faced before. She believes those vulnerable seasons make it especially important for women to protect what they consume mentally and spiritually and stay grounded in their faith.
They also get into the science and lifestyle factors that may affect how women experience perimenopause. Dr. Jen discusses progesterone decline, fluctuating estrogen, blood sugar, muscle mass, stress, genetics, liver health, alcohol, inflammation, and environmental exposures. She explains why two women can enter the same stage of life and have completely different experiences.
Kerstin gets personal about giving up alcohol after her husband became sober and how her own body began reacting differently to alcohol in her forties. She and Dr. Jen talk about replacing the ritual of drinking with coffee, tea, sparkling water, date nights, and other habits while acknowledging that sometimes what people miss is not the alcohol itself but the experience surrounding it.
The conversation becomes even more candid when Kerstin talks about the dramatic drop in her libido during perimenopause. Dr. Jen discusses stress, vaginal dryness, changing hormones, communication with a spouse, foreplay, testosterone, and other approaches she uses with patients. Kerstin also shares how noticeably different her libido felt while vacationing in Italy and away from the normal stress of work, kids, and home.
Dr. Jen then answers Kerstin’s rapid-fire questions about hormone replacement therapy, peptides, GLP-1 medications, muscle, meat, supplements, and strength training. She explains why she supports bioidentical hormone replacement and properly supervised peptides and GLP-1s while emphasizing that she views them as tools to layer onto a strong health foundation rather than quick fixes.
They close with practical habits Dr. Jen believes can make a difference in midlife. Her personal staples include magnesium, creatine, inositol, regular Bible reading, prayer, Christian music, and lifting heavy weights. Her message to women is simple: building muscle, managing stress, understanding your body, and protecting your spiritual life can all become part of navigating this season with more strength.
