What do you mean by "absorbed and actual CICO"?

New frontiers in the "CICO is factually incorrect" crusade: I just read that, while all kinds of fiber burn in a calorimeter, some are partially digestible by non-ruminants and some aren't. So it's not just that fiber is more filling per calorie - it's that, when you buy processed high-fiber foods, you don't know how many human-digestible calories you're actually getting, because you don't know how hard they're going to correct the possibly-quite-deceptively-high values from the calorimeter.
