What Is a Thesis in Nutrition?

A thesis in nutrition is a lengthy piece of writing that provides details about an independent original research conducted by a student. You must work on your original topic under the supervision of a faculty committee. The process of working on thesis includes several important steps.

  • You have to write a research proposal where you give a review of a current literature, identify the gap in it, and provide details to justify your methods and research design.
  • You must do an independent research within a specific timeframe and collect, analyze, summarize, and present your data as it is required by conventions.
  • You must write the final thesis where you present your findings and discuss them.
  • You must defend the results of your original research to your supervisory committee.

Write Chapters of Your Thesis in Nutrition

After completing your research, you’ll need to describe your study in detail, report your findings, and analyze and interpret them. There are some conventions regarding the structure of thesis so you should check your department’s guidelines and consult your supervisor about the regulations concerning your course. Let’s discuss the structure that is commonly used.

Title Page

It’s the first page of your piece of writing and it has to include the title of your thesis, your name, institution’s and department’s names, and submission date. Make sure that your title has relevant keywords and tells your audience what your study is about. Some programs have strict requirements about the format of a title page so it’s better to check.


Abstract is a brief summary of your thesis – typically it should be no longer than 250-300 words. You will write this section last after you finish your thesis. It’s the best approach because at that time you’ll know very well what you are summarizing. It’s the first part of your thesis in nutrition that people will read so you should make sure that it looks convincing and give enough information to persuade your audience that your thesis is worth reading. Make sure your abstract

  • Includes information about your topic and the purpose of your study;
  • Describes research methods;
  • Gives a concise summary of the key findings;
  • States major conclusions.


In this chapter, you have to introduce your research topic, state the objectives of your study and explain its relevance. You have to provide the necessary background information to provide a context for your investigation. You need to state your research question, formulate hypothesis, explain the scope of your work and its limitations, and give an overview of the thesis structure. It’s important to make the introduction engaging and clear so that your readers can get a good understanding of your research subject, your goals, and your research design. Many researchers prefer to work on the introduction chapter at the end when they are absolutely sure what they are introducing.

Literature Review

You can’t be sure that your research is original and contributes to your field of studies unless you do an extensive reading of a variety of scholarly sources on your topic to find out what academic knowledge already exists on your specific topic. In the literature review chapter, you need to describe the current state of research on your subject, identify the gap in the existing literature, and explain what you are planning to do to address that gap.

To do that, you need to do an extensive library research, select the most relevant sources, critically evaluate them, and try to find connections and patterns. In this chapter, you can also provide an argument to justify the need for your research.


It’s one of the most important chapters of any dissertation or thesis because it allows your readers to evaluate the credibility of your results. Besides, it allows other researchers to replicate your study. You need to describe how you performed your research in detail and try to convince your audience that it was the best approach to solving your research problem. You have to provide information about methods that were used for collecting and analyzing data, procedures, materials, and techniques. You must also tell about the limitations of your study and discuss obstacles, explain how you manage to overcome them.


Now it’s time to tell about the results of your research. It’s better to structure this chapter using sub-topics, sub-questions or hypothesis. When doing a research, you may come across a number of different findings, but it’s crucial only to speak about the results that are relevant to your research question and the purpose of your study. You should find the best way to present your data – use tables, charts, and graphs to visualize important data and add value to the text of your thesis in nutrition. But you should include only those tables and graphs that present extra data and don’t repeat the information that was presented in the text of your thesis.


Here you need to review the results of your study and analyze and evaluate them in relation to wider context. You should start this chapter with summarizing some of the most important results and explain how they contribute to the existing knowledge. You need to discuss whether your findings met your initial expectations. If you got some unexpected results, you have to explain how it could happen and why. You may also speak about the alternative interpretations of your results and discuss how the limitations of your research influenced them. Besides, you can offer recommendations for further investigation on your topic.


This chapter should be much shorter than the discussion chapter. You need to summarize your research, explain what it means for the field, and why it is significant. You need to give a concise answer to your research question and summarize your central argument to remind your audience about it. It’s actually the final reflection of what you did in your thesis in nutrition and how you conducted your study. This chapter can also offer specific recommendations for practice and suggestions for further research. It’s important to emphasize your contribution to the existing knowledge and remind of what you actually have added.
