That was sobering reading. Here's a quote:

It is a moot point whether or not these individuals
would have gained to the same degree or more in the absence of
treatment but clinically, patients often indicate that the
dramatic overeating associated with post-treatment weight gain
persisted well beyond their previous weight plateau. Thus, one
of the most surprising consequences of treatment is that it could
lead to increased obesity in some individuals.

I say damn the naysayers - prove 'em wrong!
