It’s one of the biggest questions around carnivore, especially when the conversation turns to nutrient deficiencies, vitamin C, magnesium and potassium, fiber, gut health, the microbiome, and whether an all-meat diet is simply too restrictive to sustain. In this 400th episode of the Nutrition with Judy podcast, I break down four of the most common concerns about eating carnivore long term and look at what deserves a closer examination. We also get into what the nutrition research can and cannot tell us about long-term dietary safety, how nutrient variety differs from nutrient sufficiency, questions around fiber and digestive health, and what actually matters when evaluating whether a diet is working for an individual. If you follow a carnivore diet, are considering one, or are questioning whether carnivore can be sustainable for years, this episode walks through the arguments that deserve more nuance.Concern 1: Is carnivore too restrictive?Concern 2: Nutrient deficiencies and food varietyConcern 3: Fiber and gut healthConcern 4: Long-term carnivore researchWhat to consider for long-term carnivore_____ EPISODE REFERENCESSlides from episodeWork with us one-on-oneInflammation Fix _____ WEEKLY NEWSLETTER 📫 Tips and Weekly Updates JUDY CHO RESOURCES ⛑️ Work with Us 🎙️ Podcast 📕 Inflammation Fix Book 📘 Carnivore Cure Book & Elimination Diet 📚 Articles 🎁 Free Resources 📗 Complete Carnivore Diet for Beginners _____ *DISCLAIMER: This content is for educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease.

In this interview, Judy Cho and Robert examine what happened to his weight, blood glucose, ketones, energy, inflammation, hunger, and overall performance—and why his experience differed from the dramatic weight-loss results commonly shared across the keto and carnivore communities. They also review Robert’s bloodwork before, immediately after, and several weeks after the sardine challenge, including arsenic, mercury, lead, cholesterol, thyroid markers, and SHBG. The conversation explores whether sardine fasting produces unique metabolic benefits, what may actually drive the rapid changes people report, and how extreme short-term diets can affect metabolic health, binge-restriction patterns, and long-term weight-loss success. We discuss the following: Sardine challenge previewWhy Robert tested sardine fastingEating 18 sardine cans dailyGlucose rose while ketones droppedWhy people do sardine fastRestriction, bingeing, and quick fixesHeavy metals after sardine challengeThe appeal of extreme fasting Should people fear mercury in sardines? _____ EPISODE RESOURCESKeto Savage WebsiteKeto Savage YoutubeKetogenic BodybuildingSavage Perspective PodcastKeto Brick_____ WEEKLY NEWSLETTER 📫 Tips and Weekly Updates JUDY CHO RESOURCES ⛑️ Work with Us 🎙️ Podcast 📕 Inflammation Fix Book 📘 Carnivore Cure Book & Elimination Diet 📚 Articles 🎁 Free Resources 📗 Complete Carnivore Diet for Beginners _____ *DISCLAIMER: This content is for educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease.

Some practitioners warn that iodine, especially higher-dose forms such as Lugol’s iodine, may trigger thyroid dysfunction, Hashimoto’s, or hyperthyroidism, while others argue that iodine deficiency is widespread and often overlooked. In this episode, Judy Cho examines the Wolff–Chaikoff effect, iodine’s role beyond the thyroid, and why iodized salt may not provide enough iodine for optimal health. The deeper history raises an even more important question: are we blaming supplemental iodine while ignoring other exposures that may have affected thyroid health for generations? Judy explores radioactive iodine, nuclear fallout, contaminated food supplies, and the historical events that may have shaped today’s fear around iodine. She also explains why the distinction between nutritional iodine and radioactive iodine matters before deciding whether iodine is helpful or harmful.Is iodine dangerous for your thyroid?The Wolff–Chaikoff effect explainedIodine deficiency, bromide, fluoride, and chlorideThe forgotten history of radioactive iodine exposureWhat government research found about thyroid riskRadioactive iodine exposureUnderstanding the difference between supplemental iodine vs. radioactive iodine_____ EPISODE REFERENCESThyroid Dose and Risk Calculator for Nuclear Weapons Fallout for the US PopulationExposure of the American People to Iodine-131 from Nevada Nuclear-Bomb TestsCDC Fallout Study Table of ContentsChapter 8 of CDC Results US Before and After exposureHow to Take Iodine Episodes Lynne Farrow InterviewIodine EpisodesFree Iodine Guide _____ WEEKLY NEWSLETTER 📫 Tips and Weekly Updates JUDY CHO RESOURCES ⛑️Work with Us 🎙️ Podcast 📕 Inflammation Fix Book 📘 Carnivore Cure Book & Elimination Diet 📚 Articles 🎁 Free Resources _____ *DISCLAIMER: This content is for educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease.

After becoming increasingly uncomfortable with how heavily veterinary care could rely on pharmaceuticals and symptom management, she pursued additional training in acupuncture, herbal medicine, nutrition, and integrative care. Her work has focused on helping dogs and cats build better health through species-appropriate nutrition, reducing unnecessary exposures, and looking more carefully at the individual animal rather than automatically following a one-size-fits-all protocol. In this conversation, we question some of the most routine decisions pet owners are asked to make and why many of us rarely stop to examine them. We discuss what may be hiding behind familiar pet-food labels, how veterinary recommendations have changed over time, and how to think more critically about nutrition, medications, vaccines, parasite prevention, testing, and other aspects of everyday pet care. This episode is not about avoiding veterinary care; it is about becoming a more informed pet owner, understanding risks and trade-offs, and asking better questions so you can make thoughtful decisions for the animal you love. We discuss the following: Dr. Judy Keller’s backgroundPet longevity versus quality of life Foods dogs should never eatWhat’s really inside kibble?Urinary disease in catsAre all pet vaccines necessary?Potential risks of vaccinationRethinking heartworm preventionFlea prevention without routine medicationRethinking spaying and neuteringWhy fresh food isn’t considered Why working dogs choose meat When bloody diarrhea needs care _____ EPISODE RESOURCESHolistic Dog and Pet Wellness Article_____ WEEKLY NEWSLETTER 📫 Tips and Weekly Updates JUDY CHO RESOURCES ⛑️ Work with Us 🎙️ Podcast 📕 Inflammation Fix Book 📘 Carnivore Cure Book & Elimination Diet 📚 Articles 🎁 Free Resources 📗 Complete Carnivore Diet for Beginners _____ *DISCLAIMER: This content is for educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease.

Drawing from 25 years in cardiac surgery and more than 3,400 operations, he explains why insulin resistance, inflammation, metabolic dysfunction, diet, and vascular damage deserve more attention in heart disease prevention. The conversation also examines statins, coronary artery calcium scans, CT angiograms, seed oils, processed carbohydrates, red meat, vegan diets, gut health, and nutrient absorption. Dr. Ovadia shares how becoming obese and prediabetic changed his own understanding of metabolic health, and why he now focuses on helping patients avoid the operating table. We discuss the following: Dr. Ovadia’s lessons from 3,400 heart surgeriesWhy cholesterol isn't the root causePharmaceutical and food industry influenceHow diet guidelines failed patientsDr. Ovadia's personal health transformationSeed oils vs processed carbohydratesEarly warning signs of heart diseaseCoronary calcium scan and CT angiogramWhat a heart surgeon eats for breakfastDr. Ovadia’s new bookCan vegans have optimal health?When diet alone isn't enough_____ EPISODE RESOURCESNutritionist's Guide to the Carnivore DietDr. Philip Ovadia's WebsiteDr. Philip Ovadia's InstagramStay Off My Kitchen Table BookStay Off My Operating Table (First Book)_____ WEEKLY NEWSLETTER 📫 Tips and Weekly Updates JUDY CHO RESOURCES ⛑️ Work with Us 🎙️ Podcast 📕 Inflammation Fix Book 📘 Carnivore Cure Book & Elimination Diet 📚 Articles 🎁 Free Resources 📗 Complete Carnivore Diet for Beginners _____ *DISCLAIMER: This content is for educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease.
