I highly doubt that they are breaching legal boundries. Doctors only have a monopoly on formal medical advise- they do not have a monopoly on "telling people how to live". Nobody thinks their local preacher or philosopher is giving formal medical advise- so there is unlikely to be any liability at all outside of gratuitously bad behavior like telling people to drink bleach.
