Ok but I'm just not gonna continue the discussion if you make claims, tell me to google, I come back and say "didn't find anything" and you still don't support your claim with links. Feels like i'm being trolled.
ETA: this isn't about "feeling full" or "bulk" this is about how the body processes food, and extracts energy using bacteria, who feed on fiber in our diet. google "fiber gut bacteria" for what I'm talking about
