Terminalia bellirica Extract Attenuates Fat Accumulation Through Modulation of Obesity-Related Dysmetabolism in 3T3-L1 Adipocytes and High-Fat Diet-Induced Obese Mice

<i>Terminalia bellirica</i> extract (TBE) has long been utilized in Ayurvedic medicine across Indian and surrounding regions for diverse therapeutic applications. Despite its traditional prominence, systematic investigations addressing the anti-obesity efficacy and underlying mechanisms remain limited. In this study, we evaluated the anti-obesity potential of TBE using both 3T3-L1 adipocyte and high-fat diet (HFD)-induced mice model. In vitro studies using 3T3-L1 adipocytes demonstrated that TBE significantly inhibited lipid accumulation and downregulated key genes involved in adipogenesis and lipogenesis, while upregulating genes promoted lipolysis and energy metabolism. To validate these cellular effects in a physiological context, mice were randomly assigned to six groups: normal control (NC), HFD-induced obese (C), HFD with metformin (100 mg/kg b.w., PC), and HFD with TBE at 50, 100, and 200 mg/kg b.w. Consistent with the in vitro findings, TBE supplementation significantly reduced body weight gain, adipose tissue mass, and adipocyte size in HFD-induced obese mice. Taken together, these results indicate that TBE exerts anti-obesity effects through modulation of adipose tissue metabolic pathways, highlighting its therapeutic potential for obesity management.
