Round 1

Reviewer 1 Report

Abstract

The findings as stated in the abstract should be quantified.

Introduction

"This study" were used 3times successfully. The grammar could be reframed without losing its meaning.

There is no mention of specific objectives - this would inform the reader how the authors intend to achieve the aim of the study. 

This study is unique in that it covers a "few" of the most recent ..... why limit the study to a few?? Reconsider this statement. It would be appropriate to mention/include PRISMA as part of your specific objectives. 

 

Materials and Method

the reasons for selecting PubMed, Medline, Scopus and Web of Science appears vague.

Reviewer 2 Report

I would like to thank the authors for this interesting paper, also the editors for inviting me to review it.

The introduction provides key definitions and a context for the study. Arguments are made supporting the value and importance of this work. 

PRISMA is a well-known and popular tool for conducting systematic literature reviews, and is a good reliable approach for this work. The recent age of the articles adds strength and value to this work, however the sample selection is a bit small at 24 papers.

Table 1 is useful for the reader to get an idea of the papers reviewed at a glance. The study design field could be further summarised to aid readability. It would be good to add some key themes from the analysis. The additional space saved from Table 1 could provide room for deeper analysis, conclusions and recommendations.

The sample selection is a bit small at 24 papers.

Following the methodology and inclusion/ exclusion criteria lead to this number of studies.

The previews review was in 2013 and lead to 6 studies.

 

2

The study design field could be further summarized.

 

The study design field has been summarized and improved

3

Deeper analysis, conclusions and recommendations.

 

All are added to the discussion part.

Reviewer 3 Report

 A study of the literature on virtual reality for the treatment of obese or overweight people was conducted. The authors created a keyword list based on two areas: virtual reality and obesity and searched PubMed, Medline, Scopus and Web of Science databases for related publications from 2000 to 2022 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). They concluded that the use of virtual reality for self-monitoring of diet, physical activity and/or weight is effective for weight loss. The paper is well written and organized. The analysis can be done better and the bibliographic part seems to me a little reduced compared to a review paper. The quality of the figures must be improved. In my view, It s preferable to separate discussion and conclusion subsections.

Reviewer 4 Report

Τhe Abstract language  and content could be better processed so as to present in a robust manner the scope of the review as well as the research processes conducted. Regarding the Introduction section my suggestion would be to condense content respective with important key concepts and highlight the importance of VR and technology use- this section could be revised and shortened. The information on Second Life and Pocemon Go do not seem relevant to the scope of the paper. In the Introduction section it is important to define research questions addressed with the specific study. The authors do not justify the selection of PRISMA for their study- this section needs revision: more information  is needed regarding PRISMA and the aims of the study supported by it. The Data Collection processes description needs to be more specific , commenting on the scientific impact, the number of sources used etc. The section inclusion/exclusion criteria could be commented further in terms of justifying important choices. Reference and scientific justification is needed in  the use of Newcastle–Ottawa 167 Quality Assessment Scale. The information on Study Design column in Table 2 could be revised so as to be more easy to follow by the reader, in a more condensed and to the point manner. The Discussion section needs to be more extended so as to provide commentary on reported data- it is quite short in the present version of the paper.

Round 2

Reviewer 4 Report

The Abstract section presents in a clear manner the scope and aim of the review. Paragraphs 5 and 6 of the Introduction section could be merged in one. Presentation of PRISMA needs further elaboration so as to present important actions, processes and how do these seem to relate with the conducted survey- since this is a methodological choice , it needs to be justified. Reference on the Newcastle Ottawa Quality Assessment Scale is needed. In the Study Design column information is hard to follow and not all sections have been condensed. The use of key words at this point could prove helpful. The Conclusion section could be a little bit more elaborated , summarizing important content.
