Where do they work?

Many dietitians work in hospitals and outpatient clinics, often specialising in areas such as diabetes, kidney care, cancer, children or intensive care. Others work in community health services, general practice, public health, schools, sports organisations, the food industry, research or private practice. Some work in humanitarian nutrition programmes. Hours are usually regular, and the work is mostly clinic- and office-based, with a lot of time spent talking with patients.

How do you become a dietitian?

You usually need an approved bachelor's degree in nutrition and dietetics, typically three to four years, that includes supervised practice in hospitals and the community. If you already have a degree in a science such as biology, biochemistry or nutrition, you can often take a graduate-entry master's in dietetics, commonly around two years. In the United States, new dietitians now need a graduate degree as well as supervised practice and a national registration exam. After qualifying, you register with the national regulator or professional body before you can use the title dietitian.

1. Dietetics degree. A bachelor's degree in nutrition and dietetics combines biochemistry, physiology, food science and clinical nutrition with supervised placements. It usually lasts three to four years and is a main route in many countries, including the UK, Canada and Australia. Make sure the programme is approved by the national regulator or dietetics association.
2. Graduate-entry master's. Graduates in nutrition, biochemistry, biology or a related science can take a master's degree in dietetics, usually around two years including placements. This route is common in Australia and the UK and is now standard in the United States, where you also complete supervised practice and pass a national registration exam.

Do you need a licence to work as a dietitian?

In many countries, including the UK, Canada and most of the United States, "dietitian" is a protected title, and you must be registered or licensed to use it. Registration usually follows an approved degree and supervised practice, and some countries also require an exam. In other countries, such as Australia, dietitians are credentialed by a professional association rather than a legal regulator. The title "nutritionist" is often less regulated. Check the rules in the country where you want to work.

Job outlook

The growth of obesity, diabetes and other diet-related diseases, together with ageing populations, supports demand for dietitians in many countries. Public interest in nutrition is high, but so is misinformation, which makes trained professionals valuable. However, online influencers and unregistered nutritionists compete for clients in private practice. Jobs in public health services depend on funding, and in some countries there are more graduates than hospital posts.

Questions about becoming a dietitian

What is the difference between a dietitian and a nutritionist?

Dietitians are trained to treat medical conditions through diet and usually must be registered or licensed, so the title is protected in many countries. Nutritionists often work in public health, the food industry or wellness, giving general advice on healthy eating. In some countries anyone can call themselves a nutritionist, although voluntary registers exist. If you want to treat patients in hospitals, dietetics is usually the right route.

How long does it take to become a dietitian?

Usually four to six years. A bachelor's degree in nutrition and dietetics typically takes three to four years, including placements. If you take a science degree first and then a master's in dietetics, it takes around five to six years. In the United States, you need a graduate degree, supervised practice and a national exam before you can become a registered dietitian.

Can you become a dietitian with a biology degree?

Yes, in many countries. A biology, biochemistry or biomedical science degree can meet the entry requirements for a graduate-entry master's in dietetics, as long as you have studied enough human physiology and biochemistry. Programmes may ask for extra modules or relevant experience. A biology degree on its own does not let you register as a dietitian.

Do dietitians work in sport?

Yes. Some dietitians specialise in sports nutrition and work with athletes, teams and fitness organisations, helping them plan diets for training, recovery and competition. Many take extra postgraduate training in sports nutrition. These roles are popular and limited in number, so most sports dietitians also work in clinical or private practice.
