Can you help me with fiber information-Correct or not?

What does this have to do with fiber count? Am I missing something?

The conversation got a little off track because people were ragging on the idea of lots and lots of rules for what’s keto and what isn’t. That transitioned to talking about the (fictional) Keto Rules Book which is a particular pet peeve of one of our admins (Brenda Zorn) and from there to whether or not she eats raw meat (which she does).

The answer to your question is that, broadly speaking, all fiber can be subtracted from the carb count to get the net carbohydrate content of any food.

I should also add, however, that some people don’t subtract fiber and count their carbohydrates by total content finding that they need to maintain a lower total carbohydrate intake to stay in ketosis.

Yea, I don’t recall who said it, but you can’t eat a candy bar, and then drink some Metamucil to offset the carbs. It doesn’t work that way.

I think you certainly could stay in a higher range once you managed to work out the level at which you were unable to control your weight. But to be honest after 3 years I don’t find variety to be a problem

I have been avoiding avocado because it has a pretty high total carbohydrate count, but perhaps I should not worry due to the fiber. It really depends on how each of us reacts to the amount of carbs as far as staying in ketosis. I read somewhere Jimmy Moore (?) that fiber should be counted because all types of carbs stimulate insulin.

Avo is nearly all fibre, go for it ! ; - )

highly processing foods may break down the fiber to make it more digestible

This is pseudoscience. The fibre does not “break down” in normal mechanical processing. Transforming the fibre chained molecules requires chemical transformation into monosaccharides or starch - or perhaps partially digestible oligosaccharides . This will not happen without enzyme assistance, at which point, by definition, it’s no longer fibre! It doesn’t matter how finely the cellulose, for example, in your Trump Bar gets ground up by The Man’s Junk Food Mill, the molecules will still be branched in a way that is impossible for your gut to cleave into digestible lego pieces! Sure, the individual chunks of chain will be smaller, but the configuration remains the same - and inaccessible to all but your gut biome’s bacteria. I guess it’s possible that more finely ground fibre might provide more immediate surface area for butyrate production in the lower gut, but I can’t find any good evidence for this. And even if this happened, it’d be something that a keto dieter would celebrate, not regret

We need to be careful to separate fairy tale judgements (“Boo! Processed Foods Are The Bad Ogre!”) from the actual mechanisms of science, which don’t care about one’s moral opinions
