Amazing. Someone points out that the results of nudge metaanalysis are actually all publication bias. Original authors then brush it off with ”[being] a relatively young field … comes with some methodological growing pains.”
there have been big questions raised about the quality and reliability of the research suggesting that small nudges (like moving an entry field or asking people to tick a box) meaningfully affect behaviour

The role of glucagon-like peptide-1 receptor agonists in weight regain treatment or prevention after bariatric surgery: a systematic review and meta-analysis - Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity
Background Weight regain (WR) and insufficient weight loss (WL) occur in 20–25% of patients after bariatric surgery due to various factors. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown promise in promoting WL; however, evidence regarding their effectiveness in managing WL and preventing WR post-bariatric surgery remains limited. Objective This study aims to evaluate the role of GLP-1RAs in treating and preventing WR following bariatric surgery. Methods A systematic search was conducted across PubMed, Scopus, and Web of Science for studies assessing the impact of GLP-1RAs on WR after bariatric surgery. Results Our search identified 27 original studies, with 10 included in the meta-analysis involving 769 participants (392 treated with GLP-1RAs). The mean age was 44.05 years, with 30.47% male. The time interval from surgery to the initiation of GLP-1RAs treatment ranged from 1.5 to 86.7 months, with treatment durations between 4 and 12 months. The analysis showed significantly greater WL in the GLP-1RAs group compared to placebo (SMD = 0.82, 95% CI 0.23 to 1.42). Subgroup analysis for treatment durations ≤ 6 months indicated a higher WL in the GLP-1RAs group (SMD = 0.79, 95% CI 0.25 to 1.34). Adverse events were primarily gastrointestinal, with nausea significantly more frequently in the GLP-1RAs group (OR = 2.01, 95% CI 1.24 to 3.27). Conclusion GLP-1RAs effectively promote WL among participants experiencing WR after bariatric surgery. Initiating GLP-1RAs therapy shortly after surgery may help prevent WR. Further research is warranted to explore long-term outcomes and optimize treatment protocols for this patient population. Graphical Abstract
