I have seen some notes of a recent lecture given by a local "nutritionist" (?dietician). She is reported as saying that some people on a low protein diet have have experienced enhanced benefits from their levadopa. According to her, this is not always the case, however, and if after a week of dieting you do not notice any change, you can discontinue it. I would be interested in any personal comments, or references to further information on this topic Thankyou, Mark.
