Dietitians and nutritionists meet with clients to assess their current nutritional habits and health needs. They advise clients on all aspects of eating for a healthy lifestyle or to reach a goal, covering topics such as portion control, food allergies, weight loss, or weight gain. They discuss food preparation and meal plans that detail calories, nutrients, and timing of meals. Dietitians and nutritionists frequently work in hospitals, nursing homes, and clinics helping patients with specific medical needs, such as managing blood sugar in diabetes, or supplementing extra calories for very ill patients.

Hospital-based dietitians and nutritionists may work in intensive care units with doctors to manage critically ill patients and insert feeding tubes. Some dietitians may work in schools where they consult with food services and educate students on healthy eating. A bachelor’s degree in dietetics, foods and nutrition, or a related area is required for most dietitian jobs, along with a license. Many dietitians and nutritionists have advanced degrees or other specialized credentials.
