Abstract
Background Dietary components effective in weight maintenance efforts have not been adequately identified. Objective To determine the effects of changes in dietary consumption on weight loss and maintenance during the Weight Loss Maintenance clinical trial. Design Weight Loss Maintenance was a randomized controlled trial. Successful weight loss participants who completed Phase I of the trial and lost 4 kg were randomized to one of three maintenance intervention arms in Phase II and followed for an additional 30 months. Participants/setting The multicenter trial was conducted from 2003 through 2007. This substudy included 828 successful weight loss participants. Methods The Block Food Frequency Questionnaire (FFQ) was used to assess nutrient intake levels and food group servings. Carbohydrates, proteins, fats, dietary fiber, fruit/vegetable, and dairy servings were utilized as predictor variables. The FFQ was collected on all participants at study entry (beginning of Phase I). Those randomized to Phase II completed the FFQ at three additional time points: randomization (beginning of Phase II), 12 months, and 30 months. Intervention The main intervention focused on long-term maintenance of weight loss using the Dietary Approaches to Hypertension diet. This substudy examined if changes to specific dietary variables were associated with weight loss and maintenance. Statistical analyses performed Linear regression models that adjusted for change in total energy examined the relationship between changes in dietary intake and weight for each time period. Site, age, race, sex, and a racesex interaction were included as covariates. Results Participants who substituted protein for fat lost, on average, 0.33 kg per 6 months during Phase I (P Conclusions Increasing fruits, vegetables, and low-fat dairy may help achieve weight loss and main |
