Introduction
- Provide the situation update of COVID-19 in the study area.
- Line 76-78, “The current study … (Figure 1).”, the current study focus on knowledge, COVID-19, diet, and physical activity that different from the abstract (Line 21-23) address the awareness and diet. Please explain more about the current study.
- Figure 1, please provide the source of information.
Materials and methods
Participants
- Provide the sampling methods and sample size.
Results
Medical history of participants
- The authors should not repeat information similar to presented table 2.
- Table 2, please provide the total number of all participants.
Discussion

Relevance of the study:
This investigation is original, generating some scientific interest, given the role of diet to promote health and considering that covid-19 significantly altered many aspects of human daily fife, including access to food.
Title:
The title is misleading because it seems too generic, therefore I think it is important to mention that this a localized study. In this way, I recommend to modify the title
COVID-19 and diet: efforts towards balance diet for sustainable nutrition among Pakistanese university students
Or
COVID-19 and diet: efforts towards balance diet for sustainable nutrition among university students in Pakistan
Abstract:
The abstract is well organized with a brief explanation of the purpose of the study followed by a summary of the experimental methodology followed. Then the authors presented the most relevant conclusions observed, and the abstract ends with a concluding remark, highlighting the most relevant conclusion, as a “message to take home”.
Nevertheless, I think that the abstract is too generic and does not provide any concrete results. So the authors should add some quantitative results.
For example: Results showed that university students of medical discipline were slightly more aware of immunity enhancing foods and nutritive values of foods as compared to the engineering students. – you should add the values of percentages or scores of these two types, for example – x% against y% respectively.
Do this for the major findings.
Introduction:
The introduction helps to frame and contextualize the work. It presents some state of the art on a number of topics which are essential to the work that was carried out, and it serves as a justification for its purpose, also highlighted at the end of introduction.
Materials and methods:
The description of the methodologies applied to obtain and treat the data are presented very clearly. I do not have any recommendations.
Results:
The results are well presented, for example in Tables and Figures which are very elucidative and allow a good understanding of the data obtained.
Discussion and Limitations:
The discussion is very comprehensive, with relevant references cited along the text. The limitations part is also relevant to frame the results of the research.
Conclusions:
The conclusions part is also well formulated, presenting the most relevant findings of the work.
Valid and I have no comments
I confirm validity of the findings though the use of adequate techniques to treat the data
