A nutrition coach can have as little as 16 hours of training at a gym, but they may also have a doctorate — or they can be anywhere in between. Since they can’t provide medical nutrition therapy, they’re not covered by insurance.
Registered dietitians have a minimum of 1,000 hours of supervised practice and need to sit for a national exam. Because of their advanced training in medical nutrition therapy, dietitians can accept insurance for nutrition coaching services.
