Round 1

Reviewer 1 Report

Thank you for the opportunity to review very well-writen this manuscript. I would like to command the authors on the rigorous conduct of this scoping review, as well as emphasize the importance of this work on implications for policy, practice, and research. I only have a few minor comments below for the authors to address. Otherwise, happy to see this manuscript be accepted for publication.

Intro: Move 3rd sentence to first sentence

Line 49: diets should be diet

Line 66-67: unclear

Line 70: statistically should be statistical

Line 86: what does reduce serving size of menus mean?

Line 157: indicate how many authors were involved in data extraction

Line 167-168: indicate when thematic synthesis vs narrative analysis was used. Did the authors mean to indicate themes instead of categories in line 168?

Compared with Step 2, it is unclear how Step 1 was completed and who was involved in the search, screening, and data extraction

Line 214: voluntary should be voluntarily

Line 278: an should be and
