If you’re interested in the relationship between training & nutrition and how you can educate the public by teaching them the importance of healthy eating and exercise, you should become a nutritionist!

Demand for nutritionists is growing, making this the perfect time to launch or advance your career.

Are you ready to get started? Our useful guide explains how to become a nutritionist in a few simple steps!

What Does a Nutritionist Do?

The main role of a nutritionist is to educate clients and the public on diet and nutrition.

It’s important to mention, nutritionists and dietitians aren’t the same. Nutritionists can only provide general diet and lifestyle advice while dietitians can work with clients with medical illnesses.

Nutritionists can work full-time in both public and private contracted roles. You can also become self-employed, working with your own clients 1-on-1.

Here’s a brief overview of the nutritionist job description:

  • Create personalised nutrition plans
  • Work 1-on-1 with clients
  • Educate the public on diet & nutrition
  • Help clients make healthier choices
  • Advise sport professionals on how diet impacts performance

Step-by-step guide to Becoming a Nutritionist

How Much Can a Nutritionist Earn?

According to Prospects, nutritionists starting salaries can be anywhere between £22,000 to £28,000 per year in the public sector. For employed nutritionists, the average base salary reported by Indeed is £28,059.

Those working in the private sector often earn slightly more than those in the public sector, ranging between £26,000 to £32,000.

However, factors such as number of hours worked, location, and experience all influence salary and earnings. For example, nutritionists in London usually earn more than those working elsewhere.

Of course, experience and further qualifications give you access to higher paying jobs and progression opportunities. Nutritionists with plenty of experience can earn between £34,000 to £68,000.

For those who are self-employed, you have access to a wider pool of clients which allows you to offer additional services. You can also charge more by marketing yourself as a specialist if you achieve further qualifications.

How Much Does it Cost to Become a Nutritionist?

The price of nutrition courses vary greatly, from free to £9,535 at university degree level. However, exactly how much it will cost you to become a qualified nutritionist depends on who your training provider is and factors such as:

  • Your Study Method – Online courses are typically cheaper than in-person or fast-track options

  • Payment Method – Some providers offer a discount if you pay the course fees in full

  • Interest Rates – If paying in instalments, keep costs down by looking for 0% interest plans

  • Hidden Fees – Cheap courses aren’t always the bargain you think, many have hidden fees for things like resits and certificates
  • Marketing – Cost does not always equal quality, some providers set higher prices to make you think that their courses are the best

Although free nutrition courses do exist, check out our guide on why they may not always be the best option: FREE Nutrition Courses: Are They Worth It?
