Beyonce did the MC to fit a role in her upcoming movie Dream Girls. Here's some interesting information on that topic:
" 'I ate everything when it was over...the second I looked at a donut, it came back! I gained back all the weight, even the weight I didn't want to come back!' she says, laughing." ("Beyoncé: 'I'm in no rush to get married'" The Belfast Telegraph, August 25, 2006)" The Raw Food Site / Beyonce
Not really the role model for why people benefit
from it if you know what I mean.
