Sometime in the last 20 years we simply stopped talking about fiber, and both kinds play a big role in gut biota. It's like we've simply given up on it.

Probably most of us aren't getting anywhere near as much pectin in our diets as we used to, let alone vegetables.

Fiber slows the absorption of sugar so that it gives you longer lasting energy instead of spiking your blood sugar all at once.

Some time in the last 100+ years we've started talking about fiber, and the benefits are still dubious.

Dr. Zoë Harcombe - What about fiber? https://youtu.be/4KrmpK_Lckg

wait I thought fiber vanished in the 1950s due to nutritionist of the day going all in on the 'calory is all that matters' but a lot of people started to talk about fibers in the 2000s (my memory is blurry though)

The funny thing is that the anti-sugar keto people are also even more anti-fiber. They'll tell you that you just need to eat steak and fats and nothing else and fiber is part of the "healthy whole grains" lie. I'm not sure if any of them are into gut microbiome science yet.

I don't think that this is true. Keto people I've met are very into the idea of 'net carbs': carbs minus fiber.

I asked about fiber once in /r/ketoscience and everyone yelled at me for suggesting they eat a vegetable.

Oh come on, the keto subs are a bit uh, over-vigilant, but you are very clearly not telling the full story here.

Wow, some astonishing Reddit posts about this if you search /r/carnivore for "poop".

Brocoli, cauliflower, lettuce... all highly recommended by every book. You discover the need for fibers very fast when starting keto.

Exactly, as a chef we had to match the fashionable diets to our patrons and if you include brussele sprouts to that you essentially lined out the trend veg of the last ~4 years.

I go into ketosis when I need too, and have found that prolonged states of ketosis to be too limiting for an enjoyable life if you love food. BUut I cannot imagine anyone who would simply remove veg from thier diet and believe they're healthy, their is a reason many body builder guys end up with colon cancer and intestine replacements due to an exclusively high protein based diet.

I keep getting this ad on YouTube by some alpha hipster complaining about all the toxic poop in your gut, like he thinks that your GI tract would be better if it were empty all the time. That’s not how digestion works, sport. You don’t have thirty odd feet of intestines because evolution was too stupid to make a shorter trip from your mouth to your butt. Your first clue should be that it’s folded up on itself.
