Obesity causes various complications like type 2 diabetes and fatty liver, and as the proportion of obese patients increases worldwide, the discovery of new treatments has become necessary. Here, we evaluated the in vitro and in vivo anti-obesity effects of 30% ethanol extract of Adenocaulon himalaicum Edgew. (EEAH). Treatment with EEAH suppressed adipogenesis and lipogenesis via the AMP-activated protein kinase (AMPK) pathway. EEAH altered the expression of adipogenic and lipogenic proteins and impeded mitotic clonal expansion during adipocyte differentiation. Oral administration of EEAH significantly mitigated body weight gain and fat accumulation in high-fat diet-induced obese mice. EEAH regulated adipogenesis and lipid accumulation in white adipose and liver tissues. EEAH modulated plasma levels of insulin and leptin. In brown adipose tissue, EEAH induced expression of thermogenic factors. EEAH shows potential for treating obesity by reducing body weight, inhibiting lipid accumulation, and suppressing adipogenesis through the AMPK pathway.
