The law provides for the licensure of dietitians, and protects the specific titles Dietitian and Nutritionist, but does not restrict the practice of nutrition for others. The law defines a scope of practice regarding medical nutrition therapy:
From §30-35-2a of West Virginia law (link at the bottom):
(a) The primary scope of practice of licensed dietitians is the provision of medical nutrition therapy. Licensed dietitians may also perform other nutrition-related services to promote the general health, well-being and the prevention of chronic diseases or conditions.
The law then goes on to state that:
(b) Nothing in this article may be construed to prohibit or otherwise limit the practice of a profession by persons who are licensed, certified or registered under the laws of this state and who are performing services within their authorized scope of practice.
However, the law is not clear if this is only limited to license holders. Holistic providers should always use caution regarding diseases and specific medical conditions, and should not perform services for the intention of treating a medical condition using nutrition.
