New Jersey approved a licensure requirement in 2019, but the law contains a very broad exemption.
Non-licensed practitioners may never attempt to diagnose, treat, or cure, or give the impression that they may. They may not use the titles “dietitian,” “nutritionist,” or that they are in any way certified or licensed by the state.
Exemption
Under C.45:16B-8, a license is required to provide medical nutrition therapy. However the law states that the requirement to have a license shall not:
“(8) prohibit any individual from providing nutrition information, guidance,
encouragement, individualized nutrition recommendations, behavior change management, coaching, assessments, weight control services, or other nutrition care services that do not constitute medical nutrition therapy as defined in section 3 of P.L.2019, c.331 (C.45:16B-3), provided that the individual does not hold himself or herself out as a licensed dietitian nutritionist or licensed nutritionist or as a provider of medical nutrition therapy.”
