Not if it's a drastic, sudden increase. A secondary side effect of that much fiber quickly is it temporarily causes you to not absorb various minerals as you normally would. And if minerals aren't absorbed, then out they go, rather quickly. I'd post references to support it, but a quick google of sudden fiber introduction and distress will quickly show multiple results to that effect. I'll leave that up to you. Nevermind, here's a simple one right from UCLA's dining entity: http://www.dining.ucla.edu/housing_site/dining/SNAC_pdf/FactsOfFiber.pdf http://www.dining.ucla.edu/housing_site/dining/SNAC_pdf/Fact...
