Meal replacement in isolated and confined mission environments: Consumption, acceptability, and implications for physical and behavioral health

We appreciate the reviewers’ time and recommendations, and have revised the manuscript to clarify questions. The changes are summarized here.•Energy equivalent meal replacement bars (MRBs) could conserve resources in isolated and confined operational environments.•MRB implementation was associated with reduced caloric intake, weight loss, and impacts to behavioral health.•Limited variety in flavor and texture, menu fatigue, and daily MRB implementation contribute to these negative impacts.•Meal replacement is operationally feasible and moderately acceptable for short-duration (
