This literature review investigated the evolving dietary patterns and escalating obesity rates among young Malaysians, aiming to identify the root causes and offer potential solutions. As Malaysia undergoes rapid urbanization and economic development, traditional diets rich in vegetables, rice, and fish are being gradually replaced by Western-style diets high in fats, sugars, and processed foods. This shift has noteworthy implications for the health of Malaysian youth, who are experiencing a concerning rise in obesity rates. This review synthesized findings from recent studies, highlighting the critical factors contributing to this trend, including the influence of globalization, changing socio-economic conditions, and increased accessibility to unhealthy food options. This review study highlighted the urgency of implementing targeted strategies to improve dietary habits and promote healthier lifestyles among Malaysian youth. Recommendations for future research and policy interventions were provided, with an emphasis on the need for comprehensive, multi-faceted approaches that address the complex interplay of factors driving obesity to serve as a call to action for stakeholders to collaborate in developing and implementing effective interventions tailored to Malaysia’s unique cultural and socio-economic context, ensuring a healthier future for the nation’s youth.
