Hi, Jet. I didn't see this until now since maybe pings don't transfer between instances? Yep, I mass-downvoted the posts in those communities you run (I read every one of them before downvoting looking for anything even vaguely medically sound), because everything I saw existed solely to spread health disinformation in the form of the so-called "carnivore diet". It's interesting you didn't mention what those three communities are: a carnivore community you run, a community for "metabolic health" you run, and a ketogenic community you run. What you also failed to mention is that all of the posts were yours. Only you post to these cesspits; they're your own little microblog wall instead of a community, and they exist solely as a platform for you to spread known health disinformation. Meaningfully engaging on those communities would only add fuel to the dumpster fire you've created, like how engaging with other types of crackpot only amplifies their message.

The carnivore diet is widely debunked pseudoscientific nonsense which directly contradicts the continually strengthening scientific consensus that reducing animal products promotes better long-term health and which is well-known to considerably elevate the risk of chronic diseases like heart disease and cancer compared to a typical omnivorous diet. Full disclosure: I'm a vegan, and obviously I don't like this on ethical grounds, but what you're doing ethically to the animals or the environment isn't all that much worse than a typical western omnivorous diet; I care, but if this were about my pro-animal activism, I would post on /c/vegan and have 10x the impact for animal ethics than I could downvoting niche communities. No, what this is about is that you're slowly killing yourself through your delusions (fine) and then trying to trick other people to follow suit by couching your claims in half-truths and the medicalese analogue of a sovereign citizen's legalese.

There is no clinical evidence that the carnivore diet provides any health benefits.[3][17][18] Dietitians dismiss the carnivore diet as an extreme fad diet,[3][4] which has attracted criticism from dietitians and physicians as being potentially dangerous to health (see Meat § Health).[15][17][18]

It also raises levels of LDL cholesterol, which increases the risk of cardiovascular disease.[4] While carnivore diets exclude fruits and vegetables which supply micronutrients, they are also low in dietary fiber, possibly causing constipation.[4][7][5] A carnivore diet high in red meat increases the risks of colon cancer and gout.[7][31][32] The high protein intake of a carnivore diet can lead to impaired kidney function.[33]

Hilariously, this is a generous summary: Wikipedia is almost too brief about these health problems (and excludes some), and as more people like you follow this fad diet, information is likely to keep coming out about how badly it wrecks your long-term health. Unlike you, I'm a vegan for ethical reasons, and so I take health information about my diet as it comes: B12, iron, and zinc deficiency substantially more likely in vegans? Cool. Vitamin D and calcium? Cool. More likely to fracture a bone? Cool. Harder to get a good daily intake of protein (~0.8–1.0g/kg)? Cool. Harder to get lysine for a complete protein? Cool. Dairy fat intake may lower all-cause mortality? Cool. I recognize these, try to compensate for them in my own diet, and also recognize the numerous health benefits of a PBD (especially with whole foods), but I loudly advertise pros and cons to people looking at veganism for their health. I almost always recommend the Mediterranean diet and DASH alongside a plant-based one if someone is concerned only about their health. If I can be intellectually honest about the science in spite of a deeply held ethical philosophy making me want a plant-based diet to be near-universally followable, I expect you to be able to do the same for your fad.

What's especially troubling is that sometimes you're taking real public health problems – ultra-processed foods, refined grains, hyperpalatable foods loaded with sugar, etc. – and using that to manufacture opportunistic FUD: "Oh, this isn't the fault of imbalanced diets full of trash; my fad diet is the only way to fix it". I would've done the same thing if someone started /c/smokingsaves and talked about how smoking a pack a day is great for your health and in fact the decline in smoking is what's elevating cancer diagnoses. Your trash is federated to Lemmy.World, where Rule 8.1 prohibits health disinformation; it's also just completely disgusting to spread it in the first place. You're more than welcome to downvote all of my posts in /c/vegan (if I try to run to the LW admins claiming harassment, link them to this comment), except unlike you, I do my best not to platform pseudoscientific horseshit.
