> Is it evidence-backed as a causative mechanism? My understanding of the role soluble fiber plays in fruit digestion comes entirely from talks by ucsf professor of pediatrics Robert Lustig. There's a bunch of his stuff on youtube, you may have heard of the famous one Sugar: The Bitter Truth. In some talks he goes more into the role of soluble fiber, but I don't recall which, and it's a bit of a rabbithole to go digging through again. Plus it's been years since I spelunked this particular hole, it's presumably even deeper now. I'm sure if you do some digging you could find reliable info on the subject. It's not my impression that we're breaking new ground here, pretty sure dietary fiber's effects on digestion are at least partially understood scientifically at this point. Unfortunately you'll still encounter a lot of folks fixating on "the physics" and calories in vs. calories out, which ignores the fact that your body is full of living organisms. The composition of your food largely determines how much of its calories get taken up by your body vs. your guests vs. simply pass through.
