I totally get this thought, but it's good to still go. I have been to several due to health issues. A doctor has required it, so I go. I For the most part, though, I have not learned much to help my health. I still go and I try to keep an open mind. And to tell the truth, I've learned a thing or two.
If Kelli tells you to go to a nutritionist and DCC means so much to you, go to the nutritionist!! Especially since she went through that whole thing in that puff piece about working extra time with a trainer since her mom had weight issues. If you really want DCC like you say, wouldn't you stand on one foot, do the hula while yodeling, water ski while singing Kum ba ya or whatever?
