Abstract/Description:
The objective of this study was to determine the effects of a structured weight loss program that included hypocaloric diet, exercise and dietary supplementation, on weight loss, metabolic syndrome risk factors and antioxidant levels in healthy overweight and obese females. Thirty-seven healthy overweight and obese women (BMI 29.5 ± 2.3 kg/m2, 41.1 ± 7.1 yrs) participated in this study. The subjects were randomized into one of two groups: an exercise, hypocaloric diet and antioxidant supplement (LifePak®; LSANT group, n=20) or an exercise, hypocaloric diet and appetite suppression supplement (HTP Complex® and TēGreen®; LSAS group, n=17). A significant weight loss occurred in both groups after 12 weeks (LSANT: -2.8 ± 2.8 kg and LSAS: -4.3 ± 2.7 kg, p<0.001). Body fat mass, percent body fat, and waist circumference significantly improved in both groups (p<0.05). No significant difference was found between the groups for weight loss (p>0.05). However, a significant difference was found between the groups for body fat mass (LSANT: -1.8 ± 2.6 kg; LSAS: -3.4 ± 2.4 kg, p ≤ 0.05). Glucose, insulin and insulin resistance (HOMA-IR) were significantly decreased in the LSAS group (glucose: -5.0 ± 6.8 mg/dl, p=0.008; insulin: -2.6 ± 3.8 uIU/dl, p=0.013; and HOMA-IR: -0.7 ± 1.0, p=0.012) but not in the LSANT group (p>0.05). There were no significant differences (p>0.05) observed within or between the groups for cholesterol, triglycerides or LDL-c. HDL-c decreased significantly in the LSANT group (-2.9 ± 5.3 mg/dl, p=0.024) but not in the LSAS group (p>0.05). Skin carotenoid scores (SCS) increased significantly within the LSANT group (LSANT: 10950 ± 8395 SCS, p<0.001) but not the LSAS group (p>0.05). Lifestyle intervention that involves a structured hypocaloric diet and increased physical activity results in weight loss and improvements in body composition. However, supplementation with an appetite suppressant (HTP Complex®) did not enhance weight loss beyond what was achieved with a structured lifestyle intervention. Antioxidant supplementation may be of benefit during a weight loss program that incorporates physical activity and a low energy diet.
