a bowl of cereal and frozen fruit.... both are filled with carbs, the cereal will turn into glucose quite quickly, the frozen fruit will convert a bit (a few minutes) slowly, and it has some fructose as well, plus it has a bit of fiber a anti-nutrient which can block the other food your eating... so a slightly delayed glucose spike, maybe muting a bit of the cereal carbs.

I suspect your glucose is still spiking with a slight delay, if you want to see it you can get a CGM and eat the different foods and look at the real time graph of blood glucose.

Yup! A big bowl of carbs to start the day, spikes glucose, spiking insulin for 2-4 hours... which drives a hypoglycemic dip, which drives hunger.... and a day of constantly snacking on carbs begins

fun fact - the body doesnt store glucose, we only have the 5g of glucose floating around in the blood.... no wonder we get hungry so fast when we are in a glucose metabolism

This lack of formal training and examination may be why the old talking points like cico, eat less move more, fiber, whole grains, etc are so persistent and why so many MDs repeat them.

 

Every day, patients walk into clinics with diseases that, unbeknownst to them, stem from what’s on their dinner table. Yet most doctors are ill-equipped to counsel them, not for lack of care or effort, but for lack of training....

Today, most medical students receive fewer than 20 hours of nutrition training over four years of school

Recommendations to “eat less fat” or “choose whole grains” overlook metabolic realities and fail to address the underlying dysfunction driving most chronic disease.

Ketogenic and other carbohydrate-restricted diets, in particular, have been extensively studied and shown to stabilize blood sugar, improve insulin sensitivity, and, in many cases, induce remission or major improvement in chronic metabolic diseases. Yet these dietary approaches are not taught to our future physicians.

Future physicians must understand the latest science surrounding diet and metabolic health.

Histamines are heat-stable, you can destroy the bacteria that created them, but not them. This is the same rational in why cooking rotten food doesn't make it safe to eat.

[–] jet@hackertalks.com -4 points 8 hours ago* (last edited 8 hours ago) (2 children)

If you suspect an allergy or other issue stemming from a single food, eliminate that food for a time period.

That is a valid strategy, but it does take a long time. Remove one item, wait 4 weeks, repeat.

Everything you’re saying, especially trying to defend yourself via Hippocrates quote, is giving heavy fad diet vibes.

It's only a 30 day suggestion.

[–] jet@hackertalks.com -3 points 8 hours ago* (last edited 8 hours ago)

I'm aware of them, but they do have lots of inputs, they are structured to eliminate FODMAPs a type of carbohydate... there are other 30 day elimination protocols that are simpler and have less variables (i.e. removing all carbohydrates).

The reason I mentioned them at all is its a option for people who are plant based, since its impossible to eliminate all carbs on that eating pattern.

[–] jet@hackertalks.com -1 points 8 hours ago (2 children)

The pathogens, the bacteria, can produce histamines, the more surface area exposed to air, the more opportunities for this bacteria to produce histamines on the meat.

[–] jet@hackertalks.com -1 points 8 hours ago (2 children)

Sorry, I probably used the wrong word, bacteria can produce histamines as one of their byproducts. More surface area exposed to the atmosphere creates more opportunities for histamine producing bacteria to produce histamines on the meats newly expanded surface.

Grinding is a process where the inside of the meat becomes the outside of the meat, dramatically increasing the surface area, more surface area for pathogens to multiply over time. If you grind the beef and immediately cook it, then its really not a issue. However, most people buy pre-ground beef which sits around for awhile.

[–] jet@hackertalks.com -5 points 9 hours ago (4 children)

None, I'm just a dude, who loves to read about nutrition, and who has seen people get great results doing some form of elimination protocol from the most gradual of 'no processed foods' on up.

 

Most of what people are told about health is wrong.

I’m a medical doctor with over a decade of clinical experience and more than 20 years immersed in research and education. I’ve worked with patients, studied the literature, and tested these principles in the real world. What I’ve found is that the biggest drivers of health aren’t found in prescriptions or procedures, but in a handful of powerful, practical changes you can make yourself.

In this video, I break down the exact strategies I use personally and recommend to patients to dramatically improve metabolic health, reduce inflammation, and lower the risk of chronic disease. These are simple, evidence-based interventions you can start at home, often with profound results.

summerizerMedical direction

  • Medication load is used as a simple signal: needing more medication means health is worsening, and coming off medication means health is improving.
  • The point is not the number of prescriptions by itself; the point is that more things are going wrong when more drugs are needed.
  • Food is medicine because food is body fuel, and the wrong fuel produces wrong performance: sickness and disease.
  • Harmful food components can injure the body directly, anti-nutrients can block essential building blocks, and nutrient shortage can starve the system of materials for life.
  • Correcting nutrition can improve most chronic disease, and metabolic health gives the rest of the body a better chance to recover.

Sunlight

  • Sunlight is a nutrient, because light exposure increases brain-derived neurotrophic factor, which supports brain growth, repair, and neuron regrowth.
  • Sunlight also stimulates nitric oxide, improves cardiometabolic health, lowers blood pressure, and supports cardiovascular function.
  • Sunlight helps the body make vitamin D, which functions as a hormone with more than a thousand effects in the body.
  • Vitamin D supports development, mitochondrial function, hormonal regulation, sleep, and many other processes.
  • Optimizing light exposure helps optimize the systems tied to those effects.

Sleep

  • Sleep is one of the best interventions for the body and brain.
  • Averaging six hours or less each night can increase Alzheimer’s risk by more than sixfold.
  • Less than five hours per night for seven nights can push the body into a pre-diabetic state.
  • One or two weekend catch-up nights are not enough; full recovery requires about seven nights of proper sleep.
  • Seven to eight hours of sleep should be protected as a core health requirement.

Movement

  • Exercise increases BDNF and helps regulate hormones such as growth hormone and IGF-1.
  • Movement helps tissues rebuild and repair, which supports more youthful aging.
  • Exercise improves testosterone, estrogen balance, and insulin function.
  • Maintaining muscle protects against atrophy and sarcopenia, and muscle mass ties directly to longevity and cognitive function.
  • Staying active reduces the need for doctors outside accidents and emergencies.

Health design and reversal

  • Humans are designed to be healthy and to thrive, so illness usually means something is impairing the body from the environment or from personal inputs.
  • Most members of a species should be healthy by default, with only some individuals limited by serious genetic problems.
  • Even people with serious genetic diseases can improve when they apply nutrition, sunlight, sleep, movement, and metabolic health principles.
  • Clinical experience includes conditions reversing that modern medicine calls incurable.
  • Diabetes, cardiovascular disease, heart failure, autoimmunity, cognitive issues, weight problems, body composition issues, and many other problems can improve or remit.

Multiple sclerosis example

  • One patient with multiple sclerosis used a ketogenic carnivore diet and the same health principles for eight months.
  • She improved symptoms dramatically and shrank MRI lesions by more than 40% without medication.
  • Her neurologist had never seen or heard of that happening and could not explain it from the existing literature.
  • A case series is being prepared on ten people with multiple sclerosis who reversed symptoms, reduced lesions, or stayed stable for years without medication.
  • These outcomes keep reinforcing the old medical rules: fix nutrition, repair metabolic health, get sun, stay active, protect sleep, and let food be medicine.

Lab ranges

  • A major change that could revolutionize medicine tomorrow is moving lab ranges from arbitrary averages to objective optimal ranges.
  • Different labs use different ranges, even in the same town, so the same B12 or thyroid value can be normal in one place and abnormal in another.
  • Doctors make objective and prescriptive decisions from lab ranges that can be arbitrary.
  • Many labs build ranges from the first few thousand people who walk in the door, not from carefully selected healthy people.
  • A normal BMI sample is not enough, because a person can have normal BMI while still having diabetes, malnutrition, or cancer.

Animal-source nutrients and B12

  • Western diets are already hyper-vegetarian by calories, with roughly 70 to 80% of calories coming from plants.
  • A Big Mac meal can be more than 90% plant calories once buns, seed-oil sauces, fries, and sugary drink are counted.
  • Blaming meat misses that most calories in the standard Western diet come from plants.
  • B12, vitamin D, vitamin A, choline, creatine, carnitine, DHA, and EPA come solely or predominantly from animal-source foods.
  • Taking the average of a deficient hyper-vegetarian population hides deficiency inside the average.

B12 ranges and brain health

  • B12 lab ranges are often too low because they are built from populations that are already low in B12.
  • Patients with fatigue and brain fog can be told their B12 is fine even when their level can still be low enough for neurological harm.
  • B12 below 500 pmol/L can be associated with demyelination of white-matter tracts in the brain and spinal cord.
  • An Oxford paper from 2008 found that people below those B12 brackets had brain shrinkage of about 2.5% to 5.2% every five years.
  • Japan uses B12 levels above 500 as normal, and some optimal ranges put B12 above 800 or even 800 to 1,200 pmol/L.

Clinical workflow

  • Objective health decisions should use objective measures, not arbitrary averages from sick populations.
  • The average person is already sick, and the people sent for blood tests are often sicker than the average.
  • Functional-style optimal ranges reveal patterns that standard ranges can hide.
  • When the lab panel is read through an optimal lens, clinicians gain more direction for nutrition, lifestyle, and medication choices.
  • The fastest medical upgrade is changing lab ranges from random averages to objective optimal ranges for patients and clinicians.

At least once, everyone should see how their body operates with as few confounding variables as possible. Your baseline performance, feeling, mood, energy - is very valuable to know.

Elimination Diet - Remove as many variables from your total intake as possible. Ideally choose a single bioavailable food prepared very cleanly for 30 days. 

This is important because lots of people don't know what they have normalized as "getting older", or "I've always had that", or "I'm just inflamed". Skin conditions, hair issues, attention, clarity, are often reported to resolve on these type of protocols.

The most famous elimination diet demonstration was with Celiac disease during WWII, wheat/bread shortages created a accidental elimination diet in Denmark and established the link between wheat protein and Celiac.

Metabolism touches every part of the body, including the brain. Metabolism is driven by diet. Food literarily affects every part of our lives.

I think people should be aware this is a very useful tool, and if there is some persistent or difficult to nail down issue - why not try it?

elimination optionsOmnivore options - eggs, red meat are good options. Ground meat has higher histamine levels, so it would confound the results.

Pescatarian - fish are ok, but they are not biocomplete, but that shouldn't be a problem for 30 days. The "sardine fast" is a type of elimination diet protocol.

Plant Based - low fodmap diets probably eliminate the most variables, but I'm not very well read on the options

Fasting - DO NOT DO LONG FASTS WITHOUT MEDICAL SUPERVISION. Probably the the most extreme option, total elimination, not exactly your base line, but if something was bothering you in your food you would at least notice it. REFEEDING SYNDROME is a real thing, and needs to be planned for when ending the fast.

Regardless, be aware of confounders - cooking oils and fats can change also be triggers, so be deliberate in your choice. Spices, seasonings, rubs, "electrolyte mixes", marinades introduce more variables.

My BiasesI run the ketogenic and zero carb carnivore (Which is just a elimination diet I decided to live with) communities, I'm all in on that metabolic lifestyle. However, elimination protocols don't have to aligned with my biases to be effective. Even doing something as simple as 30 days without processed foods can be helpful to know for someone.

Judy Cho wrote a great eliminate diet protocol book The Carnivore Cure Which is just eating red meat for 30 days and mapping out symptoms, mood, feelings. Plus guidance on starting, and reintroducing foods to nail down triggers. But, there are many different protocols out there, you can find one that fits your requirements.

The protein requirements of a human don't change based on diet. For someone following the most common omnivore eating pattern they are already eating 15% of their energy from animal sources (i.e. the meat)... Carnivore means taking the other 75% and replacing it with fat.

Carnivore shouldn't be scary - you are already eating the meat, its just swapping the plants with natural unprocessed sources of fat.

The total muscle meat consumed stays about the same... however, the people who try it tend to get more healthy and energetic and as they become more active their protein requirements scale up a bit... but that is a happy side effect.

Effectively - switch to more fatty cuts of meat, more butter, cooking fats from animal fat instead of oil. And.... let's be honest, most people have a few extra kg they want to lose, so the body will naturally use that fat source too!

 

Yes, its generative, but it illustrates the idea

I was going to post on !fedimemes@feddit.uk but that instance has a no generative content policy.

I think a major limiter on lemmy growth are the instances that encourage talk of violence, crime, being abusive to others, and are just generally super combative... maybe not written into the instance rules, but as demonstrated by what instance admins don't enforce on their own users.

I know a schism is scary for a small society like lemmy, but I'm starting to think its necessary

if not a defederation, some protocol level whitelisting of users or comms that demonstrate the bare minimum of being able to play nicely with others (realizing this would take some novel work - like adding a user level whitelist to federation rather then the current banlist, and while were at it some eventual consistency in meta-state in bans)

Basically, the toxicity needs to be partitioned off, gated, or some level of meta-moderation for instances that wont police themselves to minimum levels of behavior. It's embarrassing to share lemmy with people I know now, given how off the wall it quickly gets.

 

TLDR: Keto avoids liver disease

Background and Aims: - Metabolic dysfunction–associated steatotic liver disease (MASLD) and its progressive form, metabolic dysfunction–associated steatohepatitis (MASH), can lead to significant morbidity and mortality in adults with type 2 diabetes (T2D) and obesity. This study evaluated whether participation in an individualized, nutrition-focused telemedicine care model emphasizing carbohydrate reduction (Virta Individualized Nutrition Therapy, VINT) was associated with reduced onset of MASLD, MASH, and advanced liver disease.

Approach and Results: - Adults with T2D, prediabetes, overweight,or obesity who enrolled in VINT (2015–2024) were identified in the Komodo Healthcare Map and matched 1:1 to usual care (UC) controls (n=5031 per group). Using 3 complementary analytic approaches, incidence and time-to-event analyses were performed for new-onset liver disease. Across all strategies, VINT participants consistently showed a lower incidence of any liver-related diagnosis (27.3 vs. 42.8 per 1000 person-years; HR=0.61, p<0.001), MASH-and-beyond (4.2 vs. 10.7; HR=0.38, p<0.001), advanced liver disease (2.8 vs. 8.7; HR=0.33, p<0.001), and any liver complications (2.0 vs. 7.7; HR=0.25, p<0.001). VINT participants who lost ≥15% body weight were at lower risk of new-onset liver disease (21.2 vs. 31.8 per 1000 person-years; HR=0.66, p=0.02) compared with VINT participants who lost less weight.

Conclusions: - Participation in individualized nutrition-focused telemedicine care was associated with significantly lower incidence and risk of new-onset MASLD, MASH, and advanced liver disease. These findings support lifestyle-first interventions that are potentially scalable to reduce liver disease burden in adults with T2D and obesity.

Fatty liver disease (MASLD) is a major cause of liver disease and even liver failure. But many are surprised to learn it’s not primarily a liver problem. Growing evidence suggests the root issue may be metabolic dysfunction affecting the entire body, and that perspective can drastically change how we approach treating and preventing it.

In this interview, Dr. Bret Scher sits down with Dr. Adam Wolfberg to discuss a newly published study in Hepatology examining how a ketogenic intervention may help prevent metabolic liver disease before it progresses.

summerizer

Metabolic dysfunction as one body-wide process

  • MAFLD/MASLD is common, preventable liver disease linked to metabolic dysfunction rather than alcohol or infection.
  • Metabolic dysfunction affects the brain, liver, blood sugar, heart, kidneys, and the body as an interconnected system.
  • Medicine is often too siloed, while liver disease, type 2 diabetes, obesity, cardiovascular disease, kidney disease, and behavioral conditions belong in the same metabolic map.

Terminology and scale

  • NAFLD was the older term for fatty liver not caused by alcohol, and MASLD/MAFLD is the metabolic-dysfunction version.
  • MASH is the more advanced inflammatory form, previously NASH, and it raises risk for cirrhosis and related hazards.
  • The prevalence figures are 25% at the opening, then 25% to 34% for NAFLD/MASLD, around 80 to 90 million Americans, with NASH at 15 to 20 million.

Why Virta studied liver outcomes

  • Virta began with a type 2 diabetes nutritional program built around low-carbohydrate/keto eating, coaching, clinician oversight, digital tools, and content.
  • The earlier diabetes trial found disease reversal in a significant majority and later showed better liver tests without a liver-focused program.
  • The original prospective work showed ALT down 3% and AST down 21%, so liver outcomes became a natural next question.

Hepatology/Komodo study design

  • The new Hepatology paper used Komodo payer-record data and compared just over 5,000 Virta patients with an identically sized matched usual-care group.
  • Matching used age, diagnoses, geography, and medications, while patient identities stayed hidden from the researchers.
  • The study was not randomized; the major limitation was that the usual-care group was out in the wild, with unknown diet, exercise, or health behavior.
  • The selection-bias issue matters, and the intervention still represents the kind of health behavior clinicians want patients to choose.

Main liver outcomes

  • Any liver-related diagnosis was lower with Virta: about 27 versus almost 43 per 1,000 person-years.
  • MASH-and-beyond or more advanced liver disease was also lower: 4.2 versus about 10 per 1,000 person-years.
  • The NNT was 65 people per year to prevent any liver-related diagnosis, which was low for prevention.
  • This was a prevention result, because the cohort was not mainly a liver-disease care cohort.

Cost and payer incentives

  • The cost analysis was not at hand, but the Virta-side total cost of care was said to fall dramatically relative to matched controls, including the price of Virta.
  • The American payment structure makes prevention hard because employers and health plans may hold financial responsibility for only two or three years.
  • Virta therefore has to show economic value within one or two years, not only long-term health value.

What drove the benefit

  • The study does not isolate coaching, keto, weight loss, cleaner eating, or the whole Virta system as the exact driver.
  • More weight loss lined up with greater liver benefit.
  • Beta-hydroxybutyrate levels did not separate higher-benefit from lower-benefit groups, so deeper nutritional ketosis was not required for the liver signal.
  • For brain-focused metabolic work, higher ketones matter more; for general metabolic health, liver prevention, weight loss, and type 2 diabetes, lower ketone levels can still be enough.

Mediterranean diet comparison

  • Search results and clinical guidance often point people toward the Mediterranean diet for fatty liver or MASLD.
  • The Mediterranean-diet literature was mixed, with some studies showing reduced liver-disease risk and others not showing it.
  • One cited Mediterranean-diet study was criticized as clinic-based adherence measurement with healthy-user and selection bias.
  • The keto/Virta prevention study warrants comparable attention when Mediterranean observational work is used as diet evidence.

Clinician takeaway

  • The expensive medication pathway now includes Wegovy/semaglutide for obesity plus liver disease at approximately F2/F3 disease.
  • The goal is to keep patients from reaching that stage by using accessible low-carbohydrate nutrition earlier.
  • A well-formulated ketogenic diet is low carb, not zero carb, and people can move into it gradually.
  • Doctors do not need to personally deliver every diet detail, because content, coaching programs, and employer or health-plan access can carry much of that burden.

Closing synthesis

  • The notable result was the NNT of 65 to prevent one serious liver complication.
  • The health signal matters more than the cost signal because liver disease is serious yet preventable.
  • The study grew from type 2 diabetes care, liver-test improvements, and then a larger prevention question.
  • Metabolic health touches the brain and body together, so improving it can affect many organ systems at once.

TLDR: People with a higher healthy eating score (plant based) had higher rates of cancer. Authors flabbergasted and are looking for confounders other then the diet (pesticides) because it can't be the diet.

Following peak tobacco incidence in the mid-1980’s there has been a large reduction in lung cancer incidence among men that has not been seen among women. Lung cancer at a young age is now more common among women than men, reversing a decades long pattern. We sought to characterize environmental exposures among young lung cancer patients to understand potential drivers of this change in the epidemiologic profile of young lung cancer patients. We analyzed 187 patients (157 females, 84%) from the Epidemiology of Young Lung Cancer (YLC) study (ClinicalTrials.gov identifier: NCT04640259) using mutation-based grouping by shared biological mechanisms: EGFR Pathway (EGFR+ERBB2), Fusion Positive (ALK+ROS1+RET+NTRK), and Other/Mixed Mutations (including MET exon 14 skipping, TP53, KRAS, BRAF, and additional alterations). Of these, 166 patients (138 females, 83.1%) completed validated food frequency questionnaires. Dietary quality was assessed using the Healthy Eating Index-2015 (HEI-2015) and compared to U.S. reference values from NHANES. Dietary categories with elevated contaminant residue potential were identified using published literature. Statistical comparisons employed one-sample t-tests against reference means and chi-square tests for categorical variables. The EGFR groups and ALK groups had tobacco use history in 32.8% and 13.4% of patients respectively. All groups had similarly high levels of oral contraceptive exposure among women (75-100%). Dietary analysis revealed that EGFR Pathway, Fusion Positive, and Other/Mixed Mutations patients demonstrated HEI-2015 scores (out of 100) of 64.9 ± 10.7, 65.5 ± 9.8, and 63.5 ± 9.5 respectively, compared with the US reference of 58. YLC women demonstrated higher dietary quality scores than men (65.6 ± 9.7 vs. 61.8 ± 11.3), both exceeded U.S. reference values of 60 for females and 56 for males. These YLC patients also consumed more foods from dietary categories associated with elevated contaminant exposure potential, as reflected by higher HEI-2015 component scores (out of 5) for total vegetables (4.2 vs. 3.5), fruits (3.3 vs. 2.5), and whole grains (3.9 vs. 2.6). YLC patients have a diet pattern of higher diet quality, with higher exposure to whole fruits, vegetables and whole grains. While these food groups are presumed to have good health benefits, there is an emerging, under-appreciated literature that produce based whole foods often contain high pesticide/herbicide contaminants. Further investigation of the role of pesticide contaminated fruits/vegetables/whole grains is timely to assess its role, if any, in the changing lung cancer prevalence over the last 4 decades

This has yet to be peer reviewed and published, but it is already in the news cycle, so here we are.

Abstract: https://www.abstractsonline.com/pp8/#!/21436/presentation/1647

 

That puts us at 0.006% of the global population. How did I arrive at 500k? I kinda made it up based on carnivore study populations, but its super duper tiny. I looked everywhere, I can't really find a solid estimate. But we are totally in the dozens of us category.

I NEVER meet another zero carb carnivore anywhere organically. Plus there is huge stigma for being a carnivore. EVERYONE thinks I'm crazy.

  • Omnivore - 73% - 6,000M
  • Flexitarian - 14% - 1,100M
  • Vegetarian - 5% - 400M
  • Pescatarian - 3% - 250M
  • Vegan - 3% - 250M
  • Zero Carb Carnivore - 0.006% - 0.5M

Using ipsos (broad strokes good enough) for the other eating pattern data

It's fine to be a minority group. Live and let live.

There are some people who simply cannot suffer us in our little corner of the internet at all. My poor little community script runs every day and bans many accounts for just downvoting all the posts in the community. https://discuss.online/modlog/696952

I've dug into the many of the non-obvious-sockpuppet accounts, and it seems most of the hate directed at us comes from our nearest neighbor at 3% total population. A group 500x more popular.

I really wish we could just be friends, let's agree that whole foods, totally unprocessed is good, and leave each other alone as allies in improving everyone's health. I'd like that. This childish animosity doesn't help anyone.

Perhaps this is just the cost of being a small fringe eating pattern, easy target for other less small groups to hate.

Eyeballing daily active users on the fediverse it looks like we have about 7,000 unique users every day. There are about 3 carnivores - which puts us at 0.04% of the lemmy population.

 

TLDR: Seed oils (vegetable oils) ARE NOT food. They are a modern invention of the industrial petrochemical complex (1915), humans are not suited to long term consumption of these food substitutes.

Conclusion - The consumption of the omega-6 polyunsaturated fat linoleic acid has dramatically increased in the western world primarily in the form of vegetable oils. OxLDL is thought to play an important role in atherosclerosis formation; however, it is the oxidised linoleic acid contained in LDL that leads to harmful OXLAMs, which induces atherosclerosis and CHD. Thus, reducing the amount of dietary linoleic acid, mainly from industrial vegetable/seed oils, will reduce the amount of linoleic acid in LDL and likely reduce oxLDL as well as the risk for CHDcoronary heart disease.

In summary, numerous lines of evidence show that the omega-6 polyunsaturated fat linoleic acid promotes oxidative stress, oxidised LDL, chronic low-grade inflammation and atherosclerosis, and is likely a major dietary culprit for causing CHD, especially when consumed in the form of industrial seed oils commonly referred to as ‘vegetable oils’.

Objective: To examine the relation between the consumption or avoidance of meat and psychological health and well-being.

Methods: A systematic search of online databases (PubMed, PsycINFO, CINAHL Plus, Medline, and Cochrane Library) was conducted for primary research examining psychological health in meat-consumers and meat-abstainers. Inclusion criteria were the provision of a clear distinction between meat-consumers and meat-abstainers, and data on factors related to psychological health. Studies examining meat consumption as a continuous or multi-level variable were excluded. Summary data were compiled, and qualitative analyses of methodologic rigor were conducted. The main outcome was the disparity in the prevalence of depression, anxiety, and related conditions in meat-consumers versus meat-abstainers. Secondary outcomes included mood and self-harm behaviors.

Results: Eighteen studies met the inclusion/exclusion criteria; representing 160,257 participants (85,843 females and 73,232 males) with 149,559 meat-consumers and 8584 meat-abstainers (11 to 96 years) from multiple geographic regions. Analysis of methodologic rigor revealed that the studies ranged from low to severe risk of bias with high to very low confidence in results. Eleven of the 18 studies demonstrated that meat-abstention was associated with poorer psychological health, four studies were equivocal, and three showed that meat-abstainers had better outcomes. The most rigorous studies demonstrated that the prevalence or risk of depression and/or anxiety were significantly greater in participants who avoided meat consumption.

Conclusion: Studies examining the relation between the consumption or avoidance of meat and psychological health varied substantially in methodologic rigor, validity of interpretation, and confidence in results. The majority of studies, and especially the higher quality studies, showed that those who avoided meat consumption had significantly higher rates or risk of depression, anxiety, and/or self-harm behaviors. There was mixed evidence for temporal relations, but study designs and a lack of rigor precluded inferences of causal relations. Our study does not support meat avoidance as a strategy to benefit psychological health.

In this episode, Dave sits down with Peter Ballerstedt, a retired forage agronomist and ruminant nutritionist known as "Don Pedro the Sod Father of the Ruminati," who brings a unique agricultural perspective to metabolic health discussions. Ballerstedt shares his 2007 transformation after reading Gary Taubes' book and how it led him to bridge agricultural science with the low-carb community. The conversation examines environmental arguments around animal agriculture, presents data on greenhouse gas emissions (12% animal vs 10% plant agriculture), explores the limitations of converting grassland to cropland, discusses the evolution of dietary guidelines since the 1970s, and examines Ballerstedt's concept of a "ruminant revolution" to address both human malnutrition and environmental concerns.
