“Super-Responders” to Liraglutide Monotherapy and the Growing Evidence of Efficacy of GLP-1 Analogues in Obesity Management: A Longitudinal Prospective Cohort Study
Bibliographic record
Abstract
Aims: Individual weight loss results achieved with Glucagon-like Peptide-1 receptor agonists (GLP-1RA) vary significantly. Our aim was to describe the characteristics of patients with obesity who achieved ≥ 20% total weight loss (TWL) on liraglutide and appraise those findings through the prism of an evolving spectrum of GLP-1RA. Methods: This longitudinal prospective cohort study included 21 patients (90.5% females, age 50 (IQR 17) years, class II/III obesity (Body Mass Index ≥ 35 kg/m2) followed at the Edmonton Adult Bariatric Clinic for 65.1 (IQR 15.5) weeks. All patients received treatment with liraglutide 3.0 mg subcutaneously daily along with involvement in an integrated lifestyle modification program. Results: Liraglutide was well-tolerated, with its benefits experienced by >90% of patients. The vast majority were consistently tracking calories (95.2%, n = 20) and protein intake (90.5%, n = 19), achieving a calorie deficit of 651 (IQR 323) kcal/day, and had their mental health conditions and psychological issues successfully managed. At 16, 26, and 52 weeks, TWL was 14.3% (IQR 3.7), 18.7% (IQR 8.8), and 25.9% (IQR 9.6), respectively (p < 0.001). Over 20% TWL was achieved by 72.2% of patients by week 52. Conclusions: A select number of patients with obesity will attain weight loss that rivals bariatric surgery using liraglutide monotherapy. Despite liraglutide being less effective compared to newer agents on the market, some individuals will respond strongly and should be considered when other therapies are inaccessible. Given the societal burden and numerous challenges faced by people with obesity, GLP-1RA should be pursued in clinical practice to assist in achieving weight loss goals while being convenient and safe.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
