I don't know of anyone claiming to be a professional, but in the forum snippet it says that this forum is "...an attempt to bring in the professionals." Just wondering who they were, if they were here.
As for personal trainers, well, I must agree with Steve. As for the Nutritionist versus the dietician, it really depends on what you need. If you have a specific medical condition that requires certain nutrients or electrolytes, then seeing a nutritionist would be your best bet.
Thanks for all the replies!
