Guide for Authors

 Ethical/Legal Considerations:
A submitted manuscript must be an original contribution not previously published (except as an abstract or preliminary report), must not be under consideration for publication elsewhere, and must, if accepted, not be published elsewhere in similar form, in any language. Each person listed as an author is expected to have participated in the study to a significant extent. Although the editors and referees make every effort to ensure the validity of published manuscripts, the final responsibility rests with the authors, not with the Journal, its editors, or the publisher. The editorial office will acknowledge receipt of your manuscript and will give you a manuscript number for reference. Address all inquiries regarding manuscripts not yet accepted or published to the Journal's editorial office.

Ethics and malpractice statements of the Journal of Nutrition Fasting and Health are based on COPE’s Best Practice Guidelines for Journal Editors and pertain to all parties involved in the publishing: the editor, the peer reviewer and the author.

All clinical studies must receive Ethical Approval by the ethics committees. 


  Patient anonymity and informed consent:
It is the author's responsibility to ensure that a patient's anonymity be carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and following all the guidelines for experimental investigation with human subjects required by the institution(s) with which all the authors are affiliated. The protocol of the study must be approved by the Institutional Review Board (IRB) or the equivalent (e.g., Research Ethics Board) where the study is conducted. Each author warrants that he or she has obtained, prior to submission, written releases from patients whose names or photographs are submitted as part of the manuscript.


  Conflicts of Interest:
Authors should disclose, at the time of submission, information on financial conflicts of interest or other interests that may influence the manuscript. Authors should declare sources of funding for the work undertaken.



Publications are made subject to copyright for the protection of the authors and the publisher. Accepted manuscripts become the permanent property of the JNFH and may not be reproduced, in whole or in part, without the written permission of the Editor.

  Authorship Criteria:

Authorship credit should be based on:

1) Substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data;

2) Drafting the article or revising it critically for important intellectual content;

3) Final approval of the version to be submitted for publication.  

All of these conditions should be met by all authors. Acquisition of funding, collection of data, or general supervision of the research group alone does not constitute authorship. All contributors who do not meet the criteria for authorship should be listed in an acknowledgments section. All authors must agree on the sequence of authors listed before submitting the article. All authors must agree to designate one author as the corresponding author for the submission. It is the responsibility of corresponding author to arrange the whole manuscript upon the requirements and to dialogue with the co-authors during the peer-reviewing and proofing stages and to also act on behalf.


  Review Process:

All contributions selected for peer review are sent to at least two, independent reviewers, designated by the editors.
JNFH's editors may seek advice about submitted papers from technical and statistical referees on any aspect of a paper that raises concerns. These may include ethical issues or issues of data or materials access. As in all publishing decisions, the ultimate decision whether to publish is the responsibility of the Editor of the journal concerned.

Decisions: The single most important criterion for acceptance is the originality of the work. However, a decision to accept is not solely based on the scientific validity of the paper's content. Other factors affecting decisions include the extent and importance of new information in the paper compared with papers previously published or under consideration; the Journal's need to represent a wide range of topics and the overall suitability for this journal. Decision letters usually, but not always convey all factors considered for a particular decision. Occasionally the comments to the author may appear to be inconsistent with the editorial decision, which takes into consideration confidential reviewers' comments to the Editor as well as the above factors.


 Manuscript Type:

   Review Articles: Body of article (Introduction to end of Discussion) must not exceed 5000 words the entire article should not exceed 30 A4 pages, including figures, tables, and references.

No literature should be cited. The structured abstract for an original investigation should be organized as follows:
Introduction: The abstract should begin with a clear statement of the precise objective or question addressed in the paper. If a hypothesis was tested, it should be stated.

 Materials and Methods: Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference; only relevant modification should be described. Also, this section should include ethical approval.

 Results: These should be clear and concise and not duplicate data in Tables. 

 Discussion: This should be relevant to the results and placed in context of the current literature. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature. 

 Conclusion: summarize your findings.


 Acknowledgements:  Acknowledgements, funding, sponsorship or grants should be written after the main text.


 Conflicts of interest: Authors must acknowledge and declare any sources of funding and potential conflicting interest, such as receiving funds or fees by, or holding stocks and shares in, an organization that may profit or lose through publication of your paper.

All references cited in the text should be listed at the end of the manuscript on a separate page. All items in the reference list should be cited in the text and conversely, all references cited in the text must be presented in the list. The Journal has adopted the Vancouver style, citing the first six authors and then adding et al. and uses page ranges.

References to periodicals should be as follows: name and initials of authors, title of paper, abbreviated journal title (conforming to those used in Index Medicus), year, and first and last pages of the article.

Legends to Figures: Legends must be submitted for all figures. Figure legends should be brief and specific and should not duplicate the body of the text. Each illustration must have a title and an explanatory legend. The title should be part of the legend and not be reproduced on the figure itself. The legends should be placed on a separate page at the end of the manuscript after references and begin with the number of the illustration they refer to. All symbols and abbreviations used in the figure including statistical information must be explained. Use scale markers in the image for electron micrographs, and indicate the type of stain used.

If fonts are used in the artwork, they must be converted to paths or outlines or they must be embedded in the files. Color images must be created/scanned and saved and submitted as CMYK files. All electronic art must be accompanied by high-resolution laser prints of the images. Files can be submitted on a 3½-inch high-density disk, a CD-ROM, or an Iomega Zip disk.

Cite tables consecutively in the text, and number them in that order. Key each on a separate sheet, and include the table title, appropriate column heads, and explanatory legends (including definitions of any abbreviations used). Do not embed tables within the body of the manuscript. They should be self-explanatory and should supplement, rather than duplicate, the material in the text.
