Lifestyle changes, especially dietary changes, are the most effective way to treat obesity. <i>Euglena</i>, a novel food, has attracted much attention. Previous studies have shown that <i>Euglena</i> is an important modulator of the host immune response. In this study, the effects of <i>Euglena</i> as a nutritional intervention in high-fat-diet-induced obese C57BL/6J mice were investigated regarding adipose tissue accumulation and lipid and glucose metabolism by gavage at the dose of 100 mg/kg bodyweight for 9 weeks. This study is one of the few to investigate, in detail, the preventive effects of dietary <i>Euglena</i> on obesity. <b>Methods:</b> Five-week-old male C57BL/6J mice were fed with a high-fat diet (HFD) to induce obesity. An obesity model was created by feeding the high-fat diet for a period of 10 weeks. Obese mice were randomized into 2 groups with the same mean body weight, and no significant differences were observed between the groups: (1) the mice in the HEG group were maintained on a high-fat diet and daily gavaged with <i>Euglena</i> (100 mg/kg body weight) dissolved in saline (<i>n</i> = 7); and (2) the mice in the HFD group were maintained on a high-fat diet and daily gavaged with saline with the same volume (<i>n</i> = 7). The experiment finished after a nine-week period. <b>Results:</b> The results showed that <i>Euglena</i> could reduce the accumulation of white body fat, including subcutaneous fat and visceral fat, and mainly targeted subcutaneous fat. <i>Euglena</i> also reduced adipocyte particle size expansion, promoted lipolysis in adipose (adipose triglyceride lipase and hormone-sensitive triglyceride lipase) and liver tissue (reduced non-esterified fatty acid content), and improved obesity-induced ectopic fat deposition and glucose tolerance. <b>Conclusions:</b> Our findings suggest that <i>Euglena</i>, as a nutritional intervention in HFDs, efficiently reduces body weight and white adipose tissue deposition. The mechanism of <i>Euglena</i> is mainly though enhancing lipolysis. It is worth noting that <i>Euglena</i> β-glucan recovers the hyperglycemia and accumulation of ectopic fat within the liver induced by HFD.
