Dr. Gary Fetke shares his professional perspective on nutrition advice and why he shifted his focus toward dietary health.

This interview explores the pivotal moments that led Dr. Gary Fetke to prioritize nutrition in his medical practice. Stephen hosts this conversation to break down how clinical observations shape our understanding of healthy eating and long-term wellness. If you are interested in the intersection of medicine and food, this discussion provides a clear look at why these dietary changes matter.

We examine the practical implications of nutrition advice and what patients need to know when evaluating their own habits. By understanding the core principles Dr. Gary Fetke advocates, you can better navigate the complex world of dietary health. This session is designed for anyone seeking a grounded, evidence-based approach to everyday wellness.

summerizerNutrition, surgery, and metabolic disease

  • Nutrition became central through orthopedics, obesity, diabetic foot disease, and infected joint implants, where metabolic illness turned routine surgical work into a weekly disaster zone.
  • Fettke's history also points there: childhood overweight, food-pyramid eating, pre-diabetes, high blood pressure, and weight loss after removing sugar.
  • The food pyramid and dietary guidelines have failed despite public uptake; over decades, higher fruit, vegetable, nut, and grain intake plus lower meat and red meat intake came with worse metabolic health.
  • Obesity is not a moral failure and not a drug-deficiency disease; the system surrounds people with food and messaging that make them fatter and then sells medical management.

Sugar, carbohydrates, seed oils, and inflammation

  • Sugar makes people hungry, carbohydrates make people fat, and polyunsaturated seed oils make people inflamed and sick.
  • The triad links modern inflammation to fructose metabolism, excess carbohydrate, and oxidizable linoleic acid load.
  • Fructose creates several inflammatory routes: liver alcohol effects, uric acid, nitric oxide inhibition, impaired blood flow, and small dense LDL particles that oxidize in blood vessel walls.
  • High blood glucose can feed the polyol pathway, creating endogenous fructose and adding another layer to the same runaway system.
  • Seed oils add long-lived oxidizable material; their four-year half-life helps explain why improvement can continue for years after removal.
  • A society eating roughly half its calories as carbohydrate plus modern seed oils is building inflammation into children, pregnancies, blood vessels, and chronic disease.

Food advice and institutional capture

  • Medical and dietetic education were shaped by Flexner, Rockefeller, Kellogg, the founding of dietetics, and modern textbook conflicts.
  • The same pathway funnels doctors toward medication and surgery while dietetics moves toward grains, fiber, plant-based messaging, and away from animal foods.
  • GP handouts and dietetic resources are still funded by food companies that benefit from cereal, grain, and plant-based messaging.
  • Dietary guidelines then control hospitals, nursing homes, schools, prisons, and armed forces, so compromised advice becomes institutional food.
  • Medical authorities punished Fettke for making nutrition understandable and for reversing diabetes outcomes from outside his formal specialty.

Low carb, keto, carnivore, and clinical experience

  • Low carb healthy fat, keto, and carnivore work because they remove the wrong fuel and supply the body with real food.
  • The practical guideline is fresh, local, seasonal, whole food based on culture and environment, avoiding added sugar and processed food.
  • Animal foods are the only fresh, local, seasonal foods available year-round in temperate climates, and nose-to-tail animal eating supplies complete proteins, fats, vitamins, and minerals.
  • Vegan diets can bring a short honeymoon because they remove junk food, but over time they leave people depleted and many people move on to low carb, keto, or carnivore.
  • Artificial sweeteners and low-carb processed products keep people psychologically tied to cravings, even when they can work as imperfect stepping stones for some people.
  • TypeOneGritters are an imperfect but powerful example: reduced sugar and carbs produced exceptional type 1 diabetes control, even with too many sweeteners.

Medicine, patients, and professional courage

  • Doctors and trainees can begin passively by asking, "I heard low carb or keto can improve diabetes, hypertension, or mental health; what do you think?"
  • Repeated N=1 stories become data when thousands of patients have the same metabolic improvements.
  • Diabetes.co.uk, personal clinical experience, local dietitians, and diabetes educators all show the same direction: food changes can improve type 2 diabetes dramatically.
  • Medicine should admit when it has been wrong, as it did with thalidomide, and stop waiting for another generation of preventable diabetic limb loss.
  • The younger generation can protect their careers during training, but eventually they have to speak when the evidence and patient outcomes are obvious.

Sugar, fruit, and seasonal biology

  • Sugar is naturally rare: fruit, honey, and breast milk are the main natural sources, and fruit exists to drive hunger and fatten animals for seasonal survival.
  • Fruit should depend on latitude and season because vitamin D and sun exposure affect fructose handling; temperate climates should mean very little fruit.
  • Modern fruit is not the same as seasonal wild fruit, and even a few berries can trigger hunger.
  • Zoos learned that feeding fruit to primates made animals sick and diabetic, because supermarket fruit is no longer biologically neutral.
  • Robert Johnson's hibernation work explains the survival switch: fructose pushes hunger, fat storage, and low-energy behavior.

Animal physiology, fat, and cholesterol

  • Cows, gorillas, and humans all send short-chain fatty acids through the portal vein; ruminants and gorillas ferment fiber, while humans need to ingest more animal fat directly.
  • Fiber advocates attack saturated fat while fiber fermentation itself makes saturated fat, which exposes a basic contradiction.
  • Cholesterol is essential for brains, cell membranes, mitochondrial membranes, hormones, vitamin D, and bile acids, and most cholesterol is made by the body.
  • Doctors who prescribe cholesterol-lowering drugs should understand cholesterol before blocking it.
  • Statins, fruit, and fiber are not as good as people have been told, and medical confidence should not outrun understanding.

Final message

  • Eat real food, avoid added sugar and processed food, use low carb or animal-based nutrition when metabolic disease is part of the problem, and stop letting corporate or ideological narratives define health.
  • The Mediterranean diet is fresh, local, seasonal, whole food based on culture and environment, not a redefined plant-based branding exercise.
  • Have fun, stay courageous, and keep challenging systems that profit from sickness.

That is alot of fascists who love vegetables...

I suspect the people who made this video don't care about facts and counter examples so much

yeah marbling in meat is a VERY UNHEALTHY SIGNAL. Don't buy marbled meat. Happily this means the cheaper meats have better lives and are healthier!

[–] jet@hackertalks.com 2 points 7 hours ago* (last edited 6 hours ago)

So far my biggest gripes are they ASSUME their medical position is true and that meat is bullshit.

I would hope they have looked at MD Georiga Ede's book - Change your diet change your mind, Noake's Ketogenic - the science of therapeutic carbohydrate restriction in human health, and Baszucki's Metabolic Mind foundation which is speed running the paper mill on diet and metabolic health.

Even if you dislike people who eat meat, you should take their position seriously if your going to credibly destroy them, that means you need to steel man their ideas, and find the best research and authorities to speak to current knowledge and efficaciousness.

Right now it's credible to say nutrition impacts mental health, and many people have a adverse reaction to carbohydrates. Autoimmune issues can also be rooted in nutrition, i.e. the discovery of gluten sensitivity was discovered by a autoimmune clinic in wwii when they had grain shortages.

Carnivore is a tool of extreme elimination, get to the base nutrition necessary for human life, and see how you do - if you improve then whatever your problem was had a nutrition component. By it's very nature the people who try carnivore are the sickest and least helped by current medicine, because why would a healthy person try a elimination diet if they don't have to? It's a giant pain in the ass.

anyway, y'all are welcome to come over to !carnivore@discuss.online if you have any questions.


Their source for keto being absolutely unhealthy and dangerous is a dietician... of course. Dietician's study a procedure, and apply the procedure, they do not do interventional science themselves, so this "expert" opinion is just against their training, not the manifest literature. She even says the main macronutrient is carbohydrates... I guess all those epileptic people not eating carbs are just a group hallucination? She says you can't survive without carbohydrates, so those epileptics must all be dead..... it's not consistent thinking - because a RD is 100% trained in the use of a ketogenic diet for epilepsy, so she could have added some nuance there... but no, guess they are all dead.

Nutrition is Nutrition, Medical is Medical.

That was important, they made a slide and bolded it! Guess that means your diet and food have no impact on medical conditions? Right? This is a professional dietician after all. All those drinkers with fatty liver disease can drink up without worrying about their medical condition. It's a great sound bite but its very narrow thinking. Obviously human health is impacted by the food people eat.

There is not shortage of actual medical doctors in the nutrition space, they really should have asked for a steel man position to tear down... keto is literally the most studied dietary pattern in the interventional literature. This RD could talk to any of the hundreds of practicing doctors on this list https://www.dietdoctor.com/low-carb/doctors/all or reach out to any of the paper authors.... but no

a 6 hour video is alot to take in, here is a automated summary of the transcript

summerizerMain thesis

  • The meat-to-fascist pipeline is a symbolic link among meat, milk, eggs, rawness, supplements, masculinity, hierarchy, and authoritarian politics.
  • Food is culture, and reactionaries use food to code modern life as decadent, feminized, impure, weak, Jewish, foreign, or controlled by elites.
  • Anti-vegetable performance can sell authoritarian identity, climate denial, and distrust of public health without making every meat eater fascist.

Jordan Peterson and carnivore grift

  • Jordan Peterson begins as a psychology professor and becomes a right-wing celebrity whose all-beef performance keeps him politically useful and culturally visible.
  • Michaela Peterson turns severe health problems into a wellness-influencer career built on increasingly restrictive elimination diets ending in beef, salt, and water.
  • The Peterson story rejects ordinary nutrition and medicine, turns tiny personal datasets into certainty, and sells miracle-diet logic around autoimmune, digestive, mood, and dental problems.
  • Liver King shows the cruder version of the same machine: raw organs, testicles, steroids, hard-man insecurity, supplement money, and a young audience taught that weakness is personal failure.
  • Carnivore influencers make protein obsession, anti-plant disgust, masculinity panic, and right-wing politics feel like one coherent lifestyle.

Nutrition and restrictive diets

  • The carnivore diet removes legumes, seeds, nuts, fruits, vegetables, and fiber while concentrating meat, dairy, organs, marrow, eggs, and raw animal flesh.
  • Dietitian Olivia says the diet has no evidence base as a health intervention and creates foreseeable risks by removing essential nutrients and food groups.
  • Developed-world diets already contain enough protein; U.S. intake is about 20% above optimal, and excess protein can displace carbohydrates and fats.
  • Erectile-dysfunction literature is used against carnivore virility marketing: low intakes of vegetables, fruits, and nuts correlate with ED, while plant-based patterns correlate with lower ED risk.
  • Fiber is useful for gut function, metabolic health, microbiome activity, satiety, and disease prevention, while Fiber Menace and carnivore constipation rhetoric are dangerous misinformation.
  • Restrictive diets also feed orthorexia: clean-eating rules, gluten fear, self-diagnosis, and moralized avoidance can turn food into purity discipline.

Food signs, meat, and masculinity

  • Meat is not naturally masculine; cultures make it masculine through religion, advertising, gender hierarchy, militarism, and class power.
  • Fast-food and meat advertising sells burgers and barbecue as male freedom, while vegetables, plant-based meat, and environmental concern are feminized or mocked.
  • Studies and articles in the transcript link vegetarianism in men with social penalties, suspected queerness, and reduced masculine status.
  • Historically, meat marks class and empire: landlords and soldiers get meat, colonized and poor people get grain, potatoes, dairy labor, hunger, and extraction.
  • Ireland becomes an example of food colonialism: beef and dairy move outward while the people producing them are underfed or starved.
  • Carol Adams ties meat eating to objectification: animals and women are turned into consumable objects while the slaughtered subject disappears as an absent referent.

Race, empire, and the primitive fantasy

  • Gail Bederman's civilized-versus-primitive masculinity explains why insecure men reach for a staged primal identity when modern work and status feel unstable.
  • Liver King, Raw Egg Nationalist, and Bronze Age Pervert sell a fantasy of ancient male vitality by flattening Indigenous peoples, hunter-gatherers, and nonwhite cultures into props.
  • Paleo fantasies overstate raw meat, mammoth hunting, and universal male hunters while ignoring human dietary adaptability and evidence for women hunters.
  • The noble-savage move praises Indigenous foodways only when useful to white anti-vegan stories and discards actual Indigenous sovereignty, culture, and political needs.
  • The soy and Cracker Barrel panics show how plant-based food becomes an identity threat even though meat eaters consume massive soy indirectly through livestock.

Wellness, conspirituality, and diagonal politics

  • Wellness grift works by validating ordinary suffering, inventing toxins or hidden causes, and selling oils, supplements, detoxes, or restrictive diets as liberation.
  • Placebo benefits can be real, but they can also bind people to false healers, false mechanisms, and products that harm bodies or delay medical care.
  • Supplements are drugs without the cultural stigma of drugs: liver injury, emergency visits, contaminated sexual-performance pills, and L-tryptophan EMS show the danger.
  • Conspirituality joins left-coded wellness, libertarian consumer freedom, anti-vaccine politics, and right-wing distrust of institutions.
  • Joe Rogan, RFK, and diagonal influencers turn anti-establishment performance into a bridge from health anxiety to reactionary politics.

Milk, industry money, and epistemic vandalism

  • Milk becomes a racial and national symbol: government milk advertising, dairy subsidies, lactase-persistence theories, and white-pride milk stunts all attach purity to dairy.
  • The transcript attacks ideas that milk explains development, democracy, or Western success as genetics dressed up as history.
  • Meat companies and allied institutes use epistemic vandalism to break public understanding of food, climate, and health.
  • The EAT-Lancet Commission becomes a central target for meat-industry backlash because it links healthy diets with environmental limits.
  • Frank Mitloehner, CLEAR, the Dublin Declaration, the Denver Call, Rick Berman groups, and meat-funded messaging form a lobbying ecosystem against reduced meat consumption.
  • Peterson's broader network links meat culture to climate denial, Daily Wire oil money, ARC, Policy Exchange, and oligarch-backed conservative coordination.

Eco-fascism, animals, and diet purity

  • Raw Egg Nationalist and Bronze Age Pervert turn eggs, raw milk, meat, bodies, and climate fear into white-masculine survival politics.
  • Eco-fascists can accept climate danger while using it to demand closed borders, racial hierarchy, and violence against migrants.
  • Animals are not symbols only: cows, calves, chickens, fish, and slaughtered bodies are feeling beings inside systems of separation, killing, leather waste, pollution, and ecological collapse.
  • Hitler's likely vegetarianism and Modi's vegetarian Hindutva show that meat refusal alone does not defeat fascism when purity, caste, nationalism, antisemitism, or Islamophobia remain intact.
  • Vegetarianism and veganism are not moral magic; they must be joined to anti-fascist, anti-caste, anti-racist, labor-aware, and animal-liberation politics.

Veganism, ecofeminism, and practice

  • The transcript defends veganism while rejecting white vegan innocence, fake-meat consumerism, racialized farm-labor exploitation, and simplistic attacks on Indigenous subsistence.
  • Plant-based eating is cast as harm reduction inside a broader fight for food sovereignty, public health, labor justice, and climate survival.
  • Ecofeminism connects domination over animals, women, nature, colonized peoples, and the body as one hierarchy of control.
  • Naturalness is a bad guide: humans are interdependent, microbial, ecological, technological, and culturally made rather than pure, separate, or stable.
  • The practical answer is mutual aid, public health, dietitian expertise, community food production, reduced meat and dairy consumption, and refusal to carry meat-industry propaganda.

Set up a dedicated Wi-Fi SSID for your iot devices, only. Allow those devices to connect to a non-internet routed VLAN.

Don't blacklist IP addresses, or Mac addresses, you're trusting the device not to change itself to get around your blacklist. Keep them completely segmented from your normal network. That's the best way

If they must have internet, you can use a white list while you're setting them up, and then remove the waitlist

Let's talk salt, primal cuts, induction cooking and pan compatibility. Oh and we're going to cook RIBEYE.

summerizerRibeye reboot

  • The episode opens with "John Wayne ate steak," the first line from Good Eats, and returns to the original ribeye lesson.
  • Alton Brown no longer cooks ribeyes with the old cast-iron sear plus oven finish because modern induction gives him more repeatable heat control.
  • The reboot is organized around the meat, the heat, and the method, because each variable changes the steak.

Meat selection

  • Ribeye comes from the rib primal, a tender and flavorful area between the chuck and short loin.
  • The farther a cut is from horn and hoof, the more tender it tends to be.
  • Ribeye stays forgiving because its fat can protect it from mild overcooking and dryness.
  • A ribeye is not a single uniform steak; each rib location changes the muscle mix.
  • The eye is the longissimus dorsi, the cap is the spinalis dorsi, the complexus grows toward the chuck, and the small costarum adds only a few bites.
  • A steak near the eighth rib gives a four-muscle, cap-heavy eating experience, while a steak near the tenth rib carves more uniformly.

Salt and drying

  • Each side gets about a teaspoon of kosher salt 8 to 12 hours before cooking.
  • The salt first pulls moisture from the surface, then dissolves into a micro brine that soaks back into the meat.
  • The uncovered refrigerator rest, plus occasional turning, dries the exterior and builds a tacky pellicle.
  • The pellicle improves browning and supports Maillard reactions when the steak hits the pan.
  • A fan can shorten the drying window to about 6 hours by increasing airflow.

Induction heat

  • Induction is used because it allows repeatable heat levels, using a 1-to-20 power scale in place of vague gas flames.
  • Induction heats compatible pans through an oscillating electromagnetic field; the cooktop gets hot mainly from pan contact.
  • A magnet test identifies useful induction cookware: stronger sticking means better ferrous compatibility.
  • Cast iron works strongly on induction but stores heat and responds slowly.
  • Aluminum fails the magnet game unless it has a steel layer.
  • Nitrided steel is tough, slick, and induction-ready, but its dark surface hides pan-sauce color cues.
  • Magnetic stainless steel gives enough induction response, faster heat control, and a bright surface for sauce cues.

Cooking method

  • The recipe uses unsalted butter, fresh black pepper, beef tallow, shallot, crushed garlic, and thyme.
  • The cold, salted steak gets melted beef tallow so it solidifies on the surface and holds pepper.
  • The steak goes straight from the refrigerator to the pan without a counter warmup.
  • Cooking starts at medium-high, about 75% power, with flips every minute for 6 minutes.
  • Frequent flipping lets heat enter one side while the other side rests, building crust while protecting the center.
  • The target is 122°F through the side, followed by lower heat and added time as needed for steak size.
  • Edge searing covers the raw-looking meat along the sides of thick ribeyes.

Pan sauce and serving

  • Peppery tallow leaves the pan after searing so burnt pepper does not dominate the sauce.
  • Butter, thyme, shallot, and briefly cooked crushed garlic form the aromatic base.
  • Garlic must stay pale because brown garlic quickly turns black and makes the dish taste burnt.
  • Ice cools the pan and supplies water for a butter emulsion, giving a simple water-butter sauce.
  • Bias slicing, butter sauce, and ribeye fat make medium doneness acceptable.
  • The result is not ultimate prime beef; it is a choice ribeye made very good through control of meat, heat, and method.

testing RFK Jr.’s reported carnivore-style diet for 30 days: meat, fermented foods, dairy, and a noon-to-7 p.m. eating window. The month produced weight loss, ketosis by urine strip, weaker workouts, intense food restriction effects, and follow-up bloodwork showing much higher LDL than earlier bloodwork.

summerizerSetup

  • The narrator used RFK Jr.'s meat-and-fermented-foods diet as a 30-day test amid chaotic health information.
  • The rules came from RFK Jr. media clips: meat, fermented foods, and a noon-to-evening eating window.
  • The tracked outcomes were starting weight, subjective wellbeing, mental clarity, and word retrieval because RFK linked them to his own results.

Rules

  • The first rule set allowed meat, fermented vegetables, yogurt, and a basic men's multivitamin.
  • Testosterone replacement and RFK Jr.'s broader supplement routine stayed outside the test because he could not list it fully.
  • The fasting window changed from noon-to-6:00 p.m. to noon-to-7:00 p.m. after the fuller RFK clip.

Daily Eating

  • Early meals were bacon, eggs, ground beef, steak, salmon, yogurt, kimchi, sauerkraut, and cheese.
  • Strict carnivore rules removed plant products, including garlic, onions, olive oil, pepper, spices, lemon, bread, and produce.
  • Home cooking became the default because restaurant meat often used plant oils, seasonings, or sauces.
  • Eating enough calories inside the narrow window was harder than eating meat itself.
  • Travel, work, movies, birthdays, moving apartments, and refrigeration limits turned normal meals into logistics problems.

Rule Confusion

  • Shawn O'Mara's materials made the rules less clear because the book used foods that strict carnivore spaces rejected.
  • The Fox segment centered meat and fermented foods, while the book included onions, garlic, blueberries, spinach, lemon, and crisp breads.
  • The "living" food idea made fermented vegetables acceptable while non-fermented vegetables became suspect.
  • RFK's ice-cream event made the diet look less rigid than the interviews made it sound, so pepper returned to the food.

Online Health Noise

  • Carnivore spaces minimized LDL concern and encouraged distrust when doctors warned about cholesterol.
  • Beef tallow and seed-oil content gave opposite answers with equal confidence, and the science stayed unverified inside the viewing experience.
  • Confident scientific language kept feeling persuasive even when the underlying point sounded weak or unclear.
  • Hank Green's explanation grounded the plant question: humans are omnivores, individual sensitivities can exist, and plants can be beneficial.
  • The fermented-food chewing explanation did not make sense because food still mixes after swallowing.

Body and Exercise

  • The corrected starting weight was 191.6 lb after a mistaken weigh-in that included the camcorder.
  • Digestion stayed mostly fine, and the first days were physically easier than expected.
  • Running and lifting became weaker around the second week, and one run slowed by about 90 seconds versus the average pace.
  • Strength training in jeans failed twice because the workouts felt unusually difficult and injury risk felt higher.
  • A urine ketone strip near the end showed that the rules were followed closely enough to reach ketosis.

Social and Mental Effects

  • The diet blocked many normal food moments: pizza, brunch, birthday food, street dogs, movie snacks, drinks, and shared meals.
  • Food became less about taste and connection and more about compliance, timing, refrigeration, and repetition.
  • Cravings intensified as the month went on, especially for bread, produce, hot dogs, cake, lime, and peanut butter and jelly.
  • The restriction briefly quieted the narrator's long-running worry about making healthy choices at every meal.
  • The restriction also revived old body-image patterns, with weight loss feeling rewarding even while the focus felt unhealthy.
  • A stress dream about eating chocolate pie and trying to vomit made the disordered side of the experiment obvious.

Results

  • On day 30, weight was 186 lb, a little over 6 lb below the corrected starting weight.
  • Extra mental clarity and word retrieval did not arrive; the result was the same self after a month of meat-heavy eating.
  • The first peanut butter and jelly sandwich after the diet tasted extraordinary because ordinary foods had been absent for weeks.
  • Follow-up bloodwork showed much higher bad cholesterol than January and triggered a medication recommendation plus primary-care follow-up.

Health System Message

  • The doctor's cholesterol message included medication and diet-and-exercise guidance, so it did not match the idea that doctors only give pills.
  • Distrust of doctors can become more powerful when people cannot afford enough medical access to have real conversations.
  • RFK's health story makes personal choice feel like the master cause of illness, but the narrator's cancer experience made that feel false.
  • Illness is not always earned by bad choices, and health does not give full control over whether people get sick.
  • A politics of total personal control can turn sickness into blame, which is the part of the diet culture the narrator found most disturbing.

We reviewed data on the American diet from 1800 to 2019. Methods: We examined food availability and estimated consumption data from 1800 to 2019 using historical sources from the federal government and additional public data sources. Results: Processed and ultra-processed foods increased from <5 to >60% of foods. Large increases occurred for sugar, white and whole wheat flour, rice, poultry, eggs, vegetable oils, dairy products, and fresh vegetables. Saturated fats from animal sources declined while polyunsaturated fats from vegetable oils rose. Non-communicable diseases (NCDs) rose over the twentieth century in parallel with increased consumption of processed foods, including sugar, refined flour and rice, and vegetable oils. Saturated fats from animal sources were inversely correlated with the prevalence of NCDs. Conclusions: As observed from the food availability data, processed and ultra-processed foods dramatically increased over the past two centuries, especially sugar, white flour, white rice, vegetable oils, and ready-to-eat meals. These changes paralleled the rising incidence of NCDs, while animal fat consumption was inversely correlated.

The mechanisms underlying impaired temperature regulation in older age, and the ability of older adults to physiologically adapt to heat exposure remain understudied. This study determined the effects of older age on the neural control of body temperature during heat stress and its plasticity in response to passive heat acclimation. The neural control of body temperature during heat stress was quantified with measurements of skin sympathetic nerve activity (SSNA), local sweat rate (LSR) and cutaneous vascular conductance (CVC) performed on older (n = 15, 60–78 years) and younger (n = 16, 21–40 years) adults before and after seven consecutive days of hot water immersion. Pre-acclimation, the onset threshold of SSNA (mean difference [95% CI]: −0.12°C [−0.38, 0.15], P = 0.518), LSR (−0.14°C [−0.37, 0.08], P = 0.265) and CVC (−0.09°C [−0.33, 0.14], P = 0.600) did not differ between older and younger adults. Heat acclimation reduced resting core temperature and increased sweating in both groups. Post-acclimation, the onset threshold of SSNA (−0.19°C [−0.36, −0.02], P = 0.024), LSR (−0.15°C [−0.29, 0.00], P = 0.036), and CVC (−0.23°C [−0.41, −0.06], P = 0.009) was reduced in older adults and these reductions did not differ from those observed in younger adults (P ≥ 0.703). These results show that older age does not alter the neural control of body temperature during heat stress, nor its plasticity to heat acclimation. The implications of these results are that passive heat acclimation may be a practical strategy to improve the physiological resilience of older adults to extreme heat events.

Belinda and I dive into the hidden history behind our dietary guidelines, tracing how a 19th-century religious health movement helped shape the modern demonization of meat and the rise of fiber, breakfast cereal, and plant-based dogma. She breaks down how the Seventh Day Adventist Church, John Harvey Kellogg, and powerful food and academic institutions worked together to manufacture the "Blue Zones" longevity story, and why the real history of Sardinia, Okinawa, Ikaria, and Loma Linda tells a very different tale about meat, pork, and animal fat. Make sure to listen to the full interview to learn more.

Belinda Fettke is an independent researcher known for investigating the historical, religious, and commercial influences on modern dietary guidelines. After her husband, orthopedic surgeon Dr. Gary Fettke, was investigated for advising patients to reduce sugar and refined carbohydrates, she began researching the origins of nutrition policy and public health messaging. Her work focuses on the intersections of religion, industry, and dietary recommendations. The interview explores how these factors may have shaped modern views on meat, plant-based diets, and chronic disease.

summerizerGary Fettke and the origin problem

  • Gary Fettke’s medical-board case began after public comments on sugar, carbohydrate reduction, type 2 diabetes, diabetic ulcers, and amputation prevention.
  • That case led from a personal defense into the origins of plant-based dietetics, fiber messaging, dietary guidelines, Blue Zones, and anti-meat ideas.

Weston A. Price and ancestral diets

  • Weston A. Price found isolated communities with strong teeth and physiques, and their foods centered on animal proteins, animal fats, vitamins A, D, and K2, sunlight, seasonal carbohydrates, and traditional preparation.
  • His work fits a recurring pattern: ancestral diets used animals, fat, fermented foods, seasonal plants, and local preparation, not modern plant-only rules.

The Adventist and Kellogg chain

  • The modern plant-based chain runs through Seventh-day Adventism, Ellen G. White, John Harvey Kellogg, medical evangelism, cereal foods, meat stand-ins, and dietetic institutions.
  • Ellen G. White’s health reform made flesh meat a spiritual and moral problem, with perfection, salvation, sexuality, and children’s plates tied to diet.
  • John Harvey Kellogg grew up inside that world and built foods designed to remove meat, eggs, milk, butter, spices, alcohol, caffeine, and stimulating foods from the table.

Health reform, industry, and dietetics

  • One temperance stream tried to address alcohol, urban poverty, dirty water, disease, factories, and social disorder.
  • A second stream fused religion, vegetarianism, Swedenborgian and Eastern-influenced ideas, anti-meat teaching, and moral reform.
  • John Harvey Kellogg built bland vegetarian foods for the sanitarium, while Will Keith Kellogg added sugar to make cereal commercially successful.
  • Lenna Frances Cooper and early dietetics carried Kellogg’s food inventions into professional nutrition, so industry was embedded from the beginning.

Adventist dietetics and plant-based evidence

  • Adventist medical evangelism used the Garden of Eden diet, clean-and-unclean meat rules, hospitals, schools, food companies, and research to move society toward plant-based eating.
  • Harry Miller’s infant soy formula is part of the same animal-food-removal project.
  • Adventist Health Studies created influential plant-based evidence, but their vegetarian and vegan categories do not mean what the public thinks those words mean.
  • Those definitions let weekly or monthly animal foods sit inside vegetarian and vegan categories, while headlines translate that into plant-only advice.
  • The public message then hides the need for supplementation and the missing animal nutrients, especially B12 and fat-soluble nutrients.

Blue Zones as marketed longevity

  • Blue Zones marketing tells people to eat 95 to 100 percent plants, retreat from meat, restrict eggs and dairy, and treat saturated-fat avoidance as a longevity pill.
  • The Blue Zones analysis rejects that interpretation because every ancestral Blue Zone checked had meaningful animal foods, and pork was a major theme.
  • Sardinia, Okinawa, Ikaria, Nicoya, and Loma Linda were turned into plant-based stories by selective timing, religious fasting periods, weak records, changed definitions, and modern marketing.
  • Adventist Health’s 2020 acquisition of Blue Zones made the Loma Linda and Adventist connection explicit.
  • Blue Zones programs then move from ancestral community life into wellness tourism, employer programs, tracking, lifestyle packages, and branded longevity services.

The five-place tour

  • Sardinia’s mountain zone was a shepherd, cheese, pork, preserved-meat, sunlight, and communal-land culture, not a year-round plant-only diet.
  • A Lent visit could make Sardinia look temporarily plant-heavy, while the rest of the year included meat, broths, stews, preserved pork, and cheese.
  • Okinawa’s koseki records, wartime destruction, U.S. occupation, pig losses, pork culture, Spam use, goat foods, and later longevity decline undermine the sweet-potato vegan story.
  • Ikaria’s Greek Orthodox fasting made half the year look plant-forward, while the rest included whole-animal feasts, goats, strong wine, smoking, seafood, snails, and shellfish.
  • Nicoya combined pork and other animal products with maize, squash, beans, nixtamalization, and local food traditions, not Mediterranean low-fat salad eating.

Guidelines, schools, and lifestyle medicine

  • The Loma Linda-Harvard line runs through Mervyn Hardinge, Frederick Stare, Adventist researchers, Walter Willett, lifestyle medicine, and dietary-guideline influence.
  • Mervyn Hardinge trained through the College of Medical Evangelists and Harvard, while Harvard food-industry funding and Adventist plant research converged on anti-animal-fat messaging.
  • Sanitarium Australia pushed low-fat, minimal-meat resources for doctors, diabetes, pregnancy, dietitians, and families while selling the products that fit that message.
  • Australian school nutrition materials connected through Life Education and Sanitarium moved children and teachers toward anti-animal-food resources.

Crete and the Mediterranean diet

  • A Mediterranean diet is not one uniform diet; it covers many countries, religions, fasting calendars, climates, and histories.
  • Crete’s postwar data came from starvation, German occupation, destroyed crops and livestock, imported ration foods, poor infrastructure, young average death age, and Rockefeller rebuilding.
  • Ancel Keys’s Crete work sits on top of Leland Allbaugh’s war-ration context and a Lent-period survey, while later olive-oil industry messaging turned that into a plant-and-oil longevity story.

Dietetics, profession, and industry

  • Early dietetics connects white Protestant reformers, domestic science, professionalized cookery, industry support, Kellogg products, and removal of food knowledge from ordinary cooks.
  • The first American Dietetic Association gathering already had industry in the room, and the profession grew beside cereal, processed foods, and scientifically formulated products.
  • The later research plan follows temperance into Kellogg’s cornflakes, Coca-Cola, dietetics, anti-meat messaging, and the professional capture of nutrition.

Pork, anthropology, and the closing arc

  • Pork functions as a test case because pork, lard, tallow, chicken fat, and olive oil expose the religious, biochemical, and cultural layers behind fat advice.
  • The pork taboo story runs through Judaism, Islam, Moses, trichinosis fears, dirtiness language, and modern anger toward pigs despite pork being practical, fatty, and nutrient-dense.
  • Gary’s case opened the door to a larger anthropology of dietetics, religion, food industry, Blue Zones, and the missing animal-food history behind nutrition education.
