Analyses were performed on chart review data from 413 obese participants who underwent weight loss at a primary care (n = 234) or weight loss (n = 179) clinic. Participants received physician-guided behavioral modification sessions and self-selected a diet plan partially or fully supplemented by meal replacements. A repeated-measures analysis of covariance was conducted with age and sex serving as covariates; significance was set at P 鈮?#xA0;.05.
In 178 subjects (43%) completing 12 weeks of the program, primary care clinics were as effective as weight loss clinics at achieving reductions in body weight (12.4 vs 12.1 kg) but better with regard to reduction in body fat percentage (3.8%vs 2.7%; P 鈮?#xA0;.05). Regardless of location, participants completing 12 weeks lost an average of 11.1%of their body weight. Participants selecting full meal replacement had greater reductions in weight and body fat percentage (12.7 kg, 3.5%) compared with participants selecting a partial meal replacement plan (8.3 kg, 2.3%).
Primary care physicians can successfully manage and treat obese patients using behavioral modification techniques coupled with meal replacement diets.
