But in fact dietary fiber is very useful for your gut bacteria (it’s sometimes called “prebiotic”), and certain kinds of fiber are associated with reduced cardiovascular disease risk (“soluble fiber”, which is in fact broken down by some gut bacteria and does provide a small amount of energy, mostly in the form of fatty acids like butyrate). Fiber can also help with satiety: high-fiber foods will fill you up a lot faster per calorie than low-fiber foods.
I’ve noticed subjectively that type-3 resistant starches make me feel much more energetic during the day. I recommend you try a few different types of fiber supplements (taken with food!) to see if you get cheap benefits.
(Resistant starches are ways that carbs can assemble which are slower to digest. RS3 happens when you heat a carb like amylose; it cools into microscopic crystals which bacteria slowly gnaw on. RS2 is the other main crystal type, which forms naturally in raw potatoes. There are also non-RS prebiotic fibers like inulin (a long fructose-based chain), acacia senegal, and xylo/galacto-oligosacharrides. Pectin is minimally digested too.
Inulin in particular is great because it feeds butyrate-producing bacteria, which seems to reduce risk of colon cancer.)
