Introduction: Obesity is a global health challenge associated with numerous metabolic disorders, including diabetes and cardiovascular disease. With growing interest in natural remedies for weight management, Limonia acidissima L., has garnered attention due to its rich bioactive composition. Objectives: This systematic review evaluates the anti-obesity potential of Limonia acidissima L., and its key bioactive compounds, including fibres, phytosterols, saponins, polyphenols, flavonoids, and ascorbic acid. Methods: A comprehensive search of databases such as PubMed, Scopus, and Google Scholar was conducted, focusing on studies published between 2000 and 2023 that investigated the metabolic effects of these compounds on lipid and carbohydrate metabolism, fat absorption, and glucose regulation. Results: The results demonstrated that Limonia acidissima L., significantly reduced body weight and fat mass, improved lipid profiles, and enhanced insulin sensitivity in both animal and human studies.Phytosterols and saponins played key roles in modulating lipid metabolism, while fibres and polyphenols were found to regulate carbohydrate metabolism and improve glycemic control. Additionally, the synergistic effects of multiple bioactive compounds amplified their collective anti-obesity potential, with few reported adverse effects, suggesting a favourable safety profile. The discussion highlights the multifaceted mechanisms through which Limonia acidissima L., combats obesity, emphasizing its ability to target multiple metabolic pathways simultaneously.While the findings are promising, the need for further large-scale clinical trials to validate these effects in diverse populations is underscored. Conclusions: In conclusion, Limonia acidissima L., emerges as a potent natural remedy for obesity management, with strong potential for inclusion in weight loss supplements and functional foods.Its bioactive compounds offer a comprehensive and safe approach to addressing the global obesity epidemic, although further research is needed to establish its long-term efficacy and optimal use.
