Anyone who has a passion for encouraging people to take control of their own health may be best suited for a role in nutrition. An interest in a holistic approach to health can also be beneficial. You'll need to be a person who is a great motivator, as well as someone with excellent interpersonal skills. That means you'll need to be a good listener and a good communicator. Because you'll likely work with multiple clients at a time, you'll need to be a good organizer and great at time management.
