Abstract

fetched live from OpenAlex

BACKGROUND: Once weight loss is achieved, the challenge is to maintain this benefit. This review reports on the effectiveness of programs for weight-loss maintenance, as part of a larger review examining treatments for overweight and obese adults. METHODS: We updated the search of a 2011 review on screening and management of overweight and obese adults. Four databases were searched. For inclusion, participants had to have lost weight in treatment and then been randomly assigned to a weight-maintenance intervention or control conditions. Studies from the 2011 review that met the criteria were included. Data were extracted and pooled (where possible) for outcomes related to weight-loss maintenance. RESULTS: Eight studies were included. Compared with control participants, intervention participants regained less weight (mean difference [MD] -1.44 kg, 95% confidence interval [CI] -2.42 to -0.47), regardless of whether the intervention was behavioural (MD-1.56 kg, 95% CI -3.10 to -0.02) or pharmacologic plus behavioural (MD -1.39 kg, 95% CI -2.86 to 0.08). Intervention participants also showed better weight maintenance than the control participants in terms of waist circumference (MD -2.30 cm, 95% CI -3.45 to -1.15) and body mass index (MD -0.95 kg/m(2), 95% CI -1.67 to -0.23). Participants undergoing pharmacologic plus behavioural interventions were more likely to maintain a loss of 5% or more of initial body weight than those in the control group (risk ratio [RR] 1.33, 95% CI 1.15 to 1.54); no difference was found for maintaining a weight loss of 10% or more (RR 1.76, 95% CI 0.75 to 4.12). INTERPRETATION: Moderate quality evidence shows that overweight and obese adults can benefit from interventions for weight maintenance following weight loss. However, there is insufficient evidence on the long-term sustainability of these benefits. REGISTRATION: PROSPERO no. CRD42012002753.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
