Abstract
PURPOSE To evaluate the efficacy, safety and availability of a 12-week, community-based obesity control program called the Protein-Rich Oriental Diet (PRO Diet) and to compare it to a conventional diet. MATERIALS AND METHODS A total of 515 overweight people (55 men and 460 women; mean age 41.9 ± 9.8 years; body mass index (BMI) 28.1 ± 3.6 kg/m²) participated in the program at two public health centers. PRO Diet was offered as the main diet recommendation for 12 weeks. As a control group, we selected a population who had followed a conventional diet program conducted at a public health center in 2006. RESULTS 177 subjects (34.3%) completed the 12-week PRO Diet program. In a per protocol (PP) analysis, the mean changes in anthropometry were (conventional program vs. PRO Diet; weight, -2.3 kg vs. -4.7 kg, p < 0.001; BMI, -1.1 kg/m² vs. -1.9 kg/m², p < 0.001; waist circumference, -3.3 cm vs. -6.8 cm, p < 0.001; fat mass, -2.0 kg vs. -4.2 kg, p < 0.001; fat % mass, -1.8% vs. -3.9%, p < 0.001). The triglyceride reduction was significantly greater (-30.16 mg/dL, p < 0.001) in the PRO Diet group after intervention compared to the conventional group. CONCLUSION The PRO Diet was an effective tool for weight loss in a community-based weight control program and well-tolerated.
