Green coffee extract modifies body weight, serum lipids and TNF-α in high-fat diet-induced obese rats

OBJECTIVE: Currently, there are many efforts to find functional nutrients for obesity management, and the green coffee extract is a potential candidate. This study aimed to examine the effect of low dose administration of green coffee extract on body weight, serum lipids, and TNF-α level in high-fat diet-induced obese rats. RESULTS: Administration of green coffee extract to high-fat diet-induced obese male Wistar rats (Rattus norvegicus) reduced body weight, total serum cholesterol, and triglyceride at the dose of 10, 20, and 40 mg/kg BW/day; lowered serum LDL-cholesterol at the treatment dose of 20 mg/kg BW/day (p < 0.05). The effective dose to decrease serum TNF-α level was 40 mg/kg BW/day, while the effective dose to improve the lipid profile was 10 mg/kg BW/day. These results support the potential use of green coffee extract as a functional nutrient in the management of obesity.
