Abstract

Introduction: The relationship between oatmeal consumption and its effects on weight status and changes in both adults and children has garnered significant interest, particularly due to the growing concerns around obesity and the need for evidence-based dietary interventions. However, the current body of literature remains inconclusive, with a lack of a comprehensive synthesis of the evidence. This systematic review aims to examine the existing studies on this topic, revealing the scarcity of research and highlighting conflicting findings. Methods: A thorough investigation was conducted through a comprehensive search of relevant literature in PubMed, Scopus, and Web of Science databases using ‘oatmeal’ OR ‘oat porridge’ AND ‘body weight’ OR ‘weight’ OR ‘waist circumference’ OR ‘BMI’ OR ‘body mass index’ OR ‘body composition’ as keywords until July 2023. Two independent reviewers screened the titles and abstracts, ultimately identifying five relevant articles for inclusion. Results: The studies reviewed revealed varying outcomes regarding the impact of oatmeal consumption on weight status. Some cross-sectional studies indicated a notable association between oatmeal intake and weight, BMI, or waist circumference reduction. In contrast, randomized controlled trials did not consistently show significant changes in weight associated with oatmeal consumption. Conclusion: Research suggested that while oatmeal may offer potential benefits for weight management, there is insufficient focused study on oatmeal specifically. Its role in weight loss appears to be modest, and it should not be regarded as a standalone solution. Therefore, oatmeal is best incorporated as part of a balanced diet and healthy lifestyle, rather than being relied upon exclusively for weight management.
