ABSTRACT
Obex is a dietary supplement to help weight loss. The purpose of this study was to evaluate the effect of Obex in overweight/obese participants with or without impaired fasting glucose. This was an open-label pilot study conducted with 40 overweight and obese subjects, 23–60 years old with a body mass index of 25–44 kg/m2 (20 participants with impaired fasting glucose [IFG] and 20 with normal glucose levels). Participants received Obex at a dose of one sachet before the two main meals of each day for 3 months. In addition to anthropometric measures and blood pressure (BP), fasting plasma glucose, lipid profile, insulin, creatinine, and uric acid were determined. Insulin resistance (HOMA-IR) and beta-cell function (HOMA-B) were assessed. Three indirect indices were used to calculate insulin sensitivity. Compared to baseline, Obex significantly reduced body weight, body mass index, waist circumference, waist/hip ratio, and waist/height ratio in both groups of participants (p <.05). In individuals without IFG, Obex improved HDL-c (high-density lipoprotein cholesterol) (p <.0001) and lowered BP (p <.05). After 3 months of Obex, subjects with IFG showed a reduction in fasting glucose concentrations (p <.0001). Compared to baseline, this group also showed improved insulin sensitivity and HDL-c (p <.05). In conclusion, the consumption of Obex contributed to weight reduction, improved glucose tolerance and insulin sensitivity, as well as HDL-c, and appears to be safe in overweight/obese adults with impaired fasting glucose. Obex may be beneficial for weight loss, indicating that further studies are required.
