> carnivores like me tend to disagree that it’s unhealthy

Why don’t you think it’s unhealthy? Would you argue the reverse - that saturated fats are healthy?

The "lipid hypothesis" has been in retreat in mainstream medicine for years now. You can easily find lots of details, like:

For a good popular treatments I recommend

I wonder if you might have a microbiome problem, i.e. you lack the microorganisms necessary to break down certain foods such as fibres. There are now treatments which have been demonstrated to have success in restoring the missing microorganisms that lead to food intolerances, the most successful being FMT.

As I understand it the capacity of the human gut to break down insoluble fiber is quite limited, especially compared to ruminants that can turn cellulose into fatty acids in their rumen. I'm sure that a healthier gut than mine can handle insoluble fiber much better, but I'm skeptical that even healthy humans can do that by digesting a significant portion of their dietary insoluble fiber.

Humans can't really digest fiber (like ruminants), but fiber is metabolized to some degree by bacteria in the colon. Specifically the bacteria ferment fiber into butyrate which is important for immune system function and other things. If you don't get enough fiber then that is likely to cause gut microbiome problems.

Guess my objection is generally the saturated fat, and the lack of fiber, and the sauces.

But you are correct. If it is just salt and butter, then ribs is a low processed food and probably not even as bad fat wise as other cuts. Probably also not the most fatty either.

Maybe a better carnivore 'junk' food example is like someone making a 'lasagna' with just layers of hamburger and a layers of cheese. So it is just all hamburger and cheese slop.

I've done both keto and vegan. And lost weight with both.

At the moment, I'm not sure I can define which one is better.

I tried so hard to relieve my IBS problems by increasing dietary fiber. That's the standard advice for bloating and constipation, and I had it bad ... to the point of suicidal thoughts. As a long time vegetarian who lived on big salads it was no problem upping my fiber. It just didn't work. It made things worse. The only relief I could find was in fasting.

When I finally tried the low residue approach of carnivore it relieved my symptoms by the next morning. As a result I've become skeptical that either fiber or carbs are health foods for me. I'm also much more skeptical of the epistemic capacity of nutrition research.

Could that be from Lectins (red beans, black beans, lentils)? https://www.hsph.harvard.edu/nutritionsource/anti-nutrients/...

Seems like the conversation usually boils down to just the term 'fiber'.

I agree, taking extra fiber supplements can be bad, or overwhelm the gut. But you can eat vegetables, and get fiber, but at a lower volume of fiber before you get constipated.

I'm just on side that vegetables are important. And the carnivore diet people don't seem to get enough vegetables generally, and all the other nutrients in vegetables. Even thought, you can do Keto with low carb vegetables. It can be done. Thought difficult.

Also. Gluten. When I cut out Gluten, that also cut out a ton of carbs (no breads). If you just eat vegetables without grains, it is pretty low carb.

Maybe, by the time you eat just meat, or just whole plants, or even a combination of whole foods (meat and vegetables, minus grain), your are being much more healthy in general than the Standard American Diet.

really, just eating a whole baked potato can be considered low carb compared to someone downing oreo's.

Can I suggest you look at the FODMAP "diet". Go on the elimination phase to remove the potential FODMAP triggers, then if and when it gets better after a few weeks start re-introduction to see what the triggers are. For me its Garlic, Onion, Fructans in Soda drinks and most fruit.

After sorting that out I added some psyllium fibre tablets and I'm mostly sorted.
