How to Change Habits with Amy Behimer: Rational Wellness Podcast 458
Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Amy Behimer a pharmacist turned board-certified health and wellness coach who helps people with autoimmune disease implement sustainable lifestyle changes through a structured, science-backed approach to "habit architecture." Behimer explains why behavior change is difficult, emphasizing that it is a learnable skill and that motivation is optional; she breaks motivation into belief, desire, and commitment. She outlines six research-backed reasons goals fail (including forgetting, goals being too big or not desired, lack of strategies that feel good, and no place to troubleshoot) and describes tactics such as "trust in the tiny," planning, tracking, reminders, support squads, environmental design, and focusing on one to three "now" habits using a tracker. She discusses mindset, compassion over guilt, household-level change, and offers a quiz, membership, and referral options for practitioners.
Dr. Amy Behimer is a pharmacist turned board certified health and wellness coach, and she specializes in helping people with autoimmune disease implement sustainable lifestyle changes. After her own diagnosis, she recognized that even the most precise. [00:02:00] Functional medicine recommendations fail without a repeatable system for behavior change. She now teaches a structured science-backed approach to habit architecture that helps patients move from knowing what to do to consistently doing it. Amy is the host of the Autoimmune Health Secrets Podcast. She's the founder of Club Habit Hub, where she works with high information patients who want better outcomes without burnout. Amy, thank you so much for joining us.

Rethinking Mental Health: A Functional Medicine Approach with Dr. Hyla Cass: Rational Wellness Podcast Episode 014
[If you enjoy this podcast, please give us a positive review on Itunes, so more people will find The Rational Wellness Podcast]
Podcast Details
Dr. Cass said it was natural for her to look at natural causes of psychiatric disorders, including diet, lifestyle, and genetics, rather than the pharmaceutical approach. She feels that it is shameful that even very young children are placed on medications, when we don't even know what effects these meds might have on developing brains.
I asked Dr. Cass why it appears as though we have a rising epidemic of depression, bipolar disorder, and ADHD among young people today. Dr. Cass said that this is due to poor diet--too many refined carbs and sugar, a lack of vegetables, not getting a solid protein--and not running around outside and exercising and they spend most of their time inside playing video games and on their computers. Dr. Cass mentioned the problems with breakfast cereals and milk in the morning, which spike their blood sugar and so many kids have food sensitivities to dairy. And the milk has bovine growth hormone. And the wheat is genetically modified and high in gluten.
We were meant to be eating healthy, natural foods with lots of fiber to support the microbiome. And so many things damage the microbiome, including the antibiotics in the food supply and the chlorine and flouride in the water supply. To help patients we have to feed the brain and the gut with natural, healthy food. Kids need to eat more veggies. We were meant to eat and live a certain way and to interact with our tribe a certain way. And that is gone today, esp. in the cities. We have to recreate that type of lifestyle, starting with the diet. And parents need to have more meaningful interactions with their children and not just be on their phones.
Dr. Cass likes to look at the root causes of psychiatric conditions, such as blood sugar imbalances, stress and adrenal health, nutritional deficiencies, thyroid, hormonal balance, MTHFR and genetic factors that may affect our ability to make neurotransmitters.
We discussed the recent Institute of Functional Medicine conference on brain health and how Dr. Bredesen has demonstrated reversal of Alzheimer's disease with a Functional Medicine approach that he refers to as a systems approach. Dr. Bredesen started with rats and found that it is not just removing plaquing in the brain, because if you remove too much plaque, they get worse. Then he went to studying humans and found that if you look at and treat heavy metals, chemical toxicity, hormone imbalances, etc. You can't just use these medications, like Namenda and Aricept, which do nothing to reverse the course of the disorder.

Muscle as Medicine: The Science of Strength, Fat Loss & Longevity with Mike Mutzel: Rational Wellness Podcast Episode 013
Dr. Weitz interviews Mike Mutzel on some of the newest strategies to help you lose weight and get into great shape. Mike and Dr. Ben both agree that it is best if you can not only teach others how to be more fit and healthy, but also to lead your life that way. They both walk the walk as well as talking the talk. Mike explains how overtraining, such as doing excessive cardio, has negative consequences. Mike recommends weight training 4 times per week as well as doing some yoga and some high intensity cardio, such as interval training. Mike explains that you have to beat your body up in order to stimulate it to adapt and get stronger and more fit.
Mike recommends taking branch chain amino acids, specifically L-leucine, which promotes muscle growth signalling. He also recommends consuming a little caffeine prior to going to the gym, which stimulates fat burning and stimulates their nervous system. Mike also talks about the importance of getting enough protein through your diet, if you want to improve in your strength and muscle building.
Mike also talks about respecting the body's natural circadian rhythm and that antioxidants should only be taken at night, since if taken before workouts, it might interfere with the free radical stress that is part of how exercise stimulates our body's adaptation and this lead us to get stronger. Mike also likes alkaline creatine and beta alanine as performance enhancers. Beta alanine is a lactic acid buffer.
Mike talks about the importance of brown fat and how taking a cold shower will stimulate the production of brown adipose tissue, which is metabolically active. Fat is not just inert. It is immunologically and metabolically active.

Why You Have Diabetes (Even If You Eat Healthy) — The Hidden Root Causes with Dr. Jeffrey James: Rational Wellness Episode 007
2026/04/07
Dr. Jeffrey James discusses the diabetes epidemic with Dr. Ben Weitz. 01:08 Dr. Ben Weitz provides an introduction on the Diabetes epidemic in the United States
01:25 Diabetics have a 50% increased risk of dying.
01:45 Obesity and Diabetes are both caused by insulin resistance.
05:42 I asked Dr. James what is the biggest factor in our society that contributes to the increase in the rate of Diabetes and Prediabetes? Dr. James said that there is not one thing, but it probably started in the 80's when everybody got so scared of saturated fats and we went to the high carbohydrate, refined carbohydrate, and margarine diet. That didn't help things. As the advent of computers and cell phones got bigger, we started sitting around more, living a sedentary lifestyle, and this contributes to increased mortality.
06:58 Dr. James explained the role of stress and cortisol and cortisol functions to elevate blood sugar when it is low. He explained the risk of low blood sugar and how diabetics that he's worked with are more fearful of low blood sugar than high blood sugar.
07:48 Dr. James explains that while sleeping, since you are not eating, if your blood sugar level dips, your body will secrete cortisol to elevate the blood sugar. But if you have been under stress for a long period of time, instead of the adrenal cortex releasing more cortisol since you have depleted cortisol levels, then the body goes into DEF CON II and it uses epinephrine and norepinephrine. These are hormones that will stimulate your liver to release glucose into your blood stream but they have the added effect of stimulating your sympathetic nervous system and waking you up. So folks who wake up at 2 or 3 am, that may be a blood sugar dysregulation issue that results from being under so much stress that their cortisol levels are depleted.
09:35 Dr. James explains that we are not just talking about emotional stress but the stress of emfs and electricity of modern life that humans never had to deal with before.
12:32 I brought up the role of toxins in metabolism such as BPA. Dr. James mentioned a recent patient who's numbers were not making sense and she tested positive for immune responses to Bisphenyl S and A, Formaldehyde, and Benzene rings. We know that some of the plastic chemicals are endocrine disruptors, but we've been told that if we get rid of BPA that we will be fine. But the other plastic chemicals like BPS that are often substituted for BPA in BPA free containers are also endocrine disruptors. Dr. James talked about how to detox these chemicals, including using infrared sauna.
15:06 Dr. James talked about the BPA coating on cash register receipts and I mentioned that even though I buy BPA free paper, just because it doesn't add BPA to the paper, because the paper starts with recycled paper, some of which has BPA on it, it will still contain BPA. And of course money all has traces of BPA on it from those who touch receipts and then touch the money.
16:18 Dr. James noted that the problem is not just BPA, but the onslought of chemicals that are endocrine disruptors that we get exposed to.

Energy Allocation System: A New Framework for Fatigue, Thyroid Labs, and Chronic Conditions with Dr Corey Schuler and moderator Dr. Ben Weitz
Dr. Ben Weitz hosts Dr. Corey Schuler to discuss Schuler's International Journal of Molecular Sciences paper proposing the Energy Allocation System, a framework suggesting many chronic conditions reflect how the body budgets limited metabolic energy across systems rather than isolated organ failure or simple hormone deficiency. They explain mitochondrial reserve capacity, why adding thyroid or sex hormones can be counterproductive when the body is intentionally downregulating function, and how stress physiology can shift thyroid markers (including reverse T3). Schuler shares a case of a high-performing executive with sleep disruption and worsening free T3 trends where urinary hormones and CGM data showed high cortisol and nocturnal hypoglycemia; treatment focused on stress support, diet changes, and supportive nutrients rather than hormone replacement. They address Hashimoto's testing, nuanced iodine dosing, iron assessment, wearable data, proposed phenotype-based research, and where to find the paper and contact Schuler.

Podcast Highlights
Rethinking Probiotics: Keystone Anaerobes, Butyrate, and Microbiome Ecosystems with Designs for Health
Dr. Ben Weitz introduces the Rational Wellness Podcast episode challenging the assumption that gut issues are solved by adding more traditional probiotics, arguing microbiome repair is an ecosystem and function problem. He interviews Dr. Oscar Cozo and Danielle Arnold of Designs for Health about differences between transient aerobic probiotics (e.g., lactobacillus/bifidobacteria) and keystone anaerobic strains that form the microbiome's foundation, can engraft, drive down gut oxygen, and support cross-feeding. They discuss live, refrigerated delivery for anaerobes; a spore-capable keystone strain (Anaerostipes); and a case study showing improved food allergies, normalization of Akkermansia, increased butyrate-related effects, and reduction of opportunists without antimicrobials. They cover butyrate's roles (tight junctions, mucus, immune regulation, HDAC inhibition), fiber and resistant starch strategies, stool testing (GI-MAP additions for anaerobes and short-chain fatty acids), diet restriction concerns, and practitioner support and case report publishing with Designs for Health.

How to Interpret the GI-MAP Stool Test for Functional Gut Health Insights
Dr. Ben Weitz introduces the Rational Wellness Podcast and explains how to interpret a functional medicine stool test, focusing on the GI-MAP from Diagnostic Solutions, to assess gut health beyond conventional pathogen screening. He emphasizes first ruling out serious conditions via careful history and gastroenterology evaluation (e.g., colonoscopy/endoscopy), then using comprehensive stool testing alongside other tests like SIBO breath and organic acids. He reviews GI-MAP sections covering acute vs chronic pathogens (e.g., C. difficile), H. pylori and key virulence factors, commensal and keystone species (e.g., Akkermansia, Faecalibacterium, Roseburia), dysbiosis and possible SIBO-related microbes (Methanobrevibacter, Desulfovibrio), fungi/candida and SIFO considerations, parasites, and functional markers including steatocrit, elastase, beta-glucuronidase, occult blood, secretory IgA, anti-gliadin IgA, inflammatory markers, zonulin, and antibiotic resistance genes.

The Hidden Causes of Autoimmune Disease (Dr. Arland Hill) — How to Reverse It: RWP6
2026/02/24
The Hidden Causes of Autoimmune Disease (Dr. Arland Hill) — How to Reverse It: RWP6. Dr. Arland Hill is a Functional Medicine Clinician and Author of "Platform Food, Function, Freedom.com." Dr. Hill has an in depth conversation with Dr. Ben Weitz about Autoimmune Diseases.
Dr. Arland Hill explains the primary reasons why there has been an increase in the rate of autoimmune diseases in the United States. The mass food production has significantly altered what is now classified as food as compared to that prior to the 1940's. The combination of drastic changes in our diet and increased toxin exposure in a post-industrialized society has contributed to the rise in autoimmune disease.
An important variant is the effect of stress. Stress breaks down the body's systems, which can create dysregulation in the immune system. This opens the door for leaky gut syndrome and can manifest in autoimmune issues. Environmental and food toxins coupled with increased stress levels can be the perfect breeding ground for autoimmune diseases to develop. However it is important to note that each of these individual factors can cause autoimmune disease to manifest on their own.
Western medical doctors treat diseases by providing medications that suppress the immune system such as corticosteroids, chemotherapy agents and newer injectables. TNF alpha blocking agents like Humira and Remicade block the immune system, which is needed to maintain homeostasis, fight off and prevent the disease processes from beginning. These drugs have very serious side effects that include depressing the immune system and worsening the effects of infections and cancer.
The Functional Medicine approach treats autoimmune diseases by looking at the underlying factors that lead to the immune system being deregulated. These factors can include disease processes such as leaky gut, food sensitivities, toxins, mold, heavy metals, nutritional deficiencies, infections, etc. Functional Medicine looks at the best strategies for correcting this by identifying the cause and catalyst of those agents.
Once you identify the cause and remove the factors that negatively affect the G.I. and immune system, a strategy to intervene can be formed. A nutritional strategy to repair and restore the gut is recommended. By reestablishing the mucosa tolerance and re-balancing the bacterial landscape, gut health is rebuilt and the immune system can function and respond unimpaired.
The podcast will cover these topics in more depth and detail. You will learn more about how toxins behave. For example, how BPA and heavy metals found in plastics insert itself in the metabolic pathway and disrupt it by misplacing nutrients. You will also learn how to test for autoimmune disease and learn the role infections play in increasing our risk. More importantly, you will learn how to improve your health and nutritional deficiencies.

How Circadian Rhythms Influence Sleep, Hormones & Bio-Timing with Dr. Corey Schuler: RWP Episode 10
2026/02/07
Corey Schuler is a holistic family nurse practitioner who discusses the circadian rhythm, the body's internal time clock, with host Dr. Ben Weitz. Both the central clock and peripheral time clocks control the metabolism of the body, our sleep, alertness, body temperature, and even our gene expression. Our modern lifestyle, lack of sleep, exposure to artificial and blue light, caffeine consumption, etc. has had a negative impact on our natural circadian rhythm and this may result in many negative health consequences. We discussed how stress, adrenal function, and the HPA axis impact our circadian rhythm.
