Nobody is saying it's impossible to eat enough fruit to be fattening. We've arguably evolved to do exactly that, since fruits are seasonal crops with brief periods of availability before rotting and vanishing until next season. We binge when they're available (and love sweets accordingly), storing some energy for the coming period of scarcity. But it's true that intact fruits include soluble dietary fiber. The soluble fiber interferes somewhat with the small intestine's access to the sugars locked up in the goop as it passes through, to become flatulence via your guests living in the colon. Just look at an insulin index including fruits to see how they compare, there's a small example on wikipedia @ https://en.wikipedia.org/wiki/Insulin_index#Explanation_of_Index https://en.wikipedia.org/wiki/Insulin_index#Explanation_of_I...

Right. That makes sense and is what I am familiar with. Is it evidence-backed as a causative mechanism? I like the Insulin Index page. That seems like reasonable evidence.

  > 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.

    Oooh. Thanks for the Lustig recommendations! Much appreciated. I have recently started appreciating the gut flora stuff after discovering that there’s a whole class of artificial sweeteners that not only gives me the runs (easy to handle) but also wrecks my mood (harder to detect since it borks my detection mechanism). On the bright side, if I’m willing to accept the pain, weight loss is trivial. Smash the Nick’s and Halo Top for a week, compensate for mood with a Barry’s Bootcamp every day, come out the other side stronger and lighter.

When I visited a small island in Belize, I went out on a tiny sailboat with a middle aged local and his teenage son. At lunch time, he grabbed his gut and proclaimed that he ate too many bananas, and then promptly diced up a pineapple for everyone.
