Maine provides for the licensure of dietitians, and restricts the practice of nutrition to only those with a license. Under this law you cannot advertise or be perceived as “assessing nutritional needs of individuals and groups” etc. You also cannot do or say anything that would give the impression that you are licensed, registered, or call yourself a nutritionist or dietitian.
According to the state law, you can provide general nutrition-related information without a license. This definition of “general nutrition-related information” is not expanded upon in the law
State and federal employees in cooperative extension food and nutrition programs do not require licenses.
You can market or distribute food, food materials, or dietary supplements and further explain how to use or to prepare those products.
You can provide weight control services as long as the program has a recommendation for physician consultation or procedures which require physician referral when medical conditions (heart disease, cancer, etc) exist and has been reviewed by, consultation is available from, and no change to the program can be initiated without approval of a licensed or registered dietitian.
