The Impact of Preoperative Eating Habits on Weight Loss After Metabolic Bariatric Surgery.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEating disorders and disordered eating habits are frequently identified among metabolic and bariatric surgery (MBS) patients. However, how these factors may affect postsurgical outcomes has not been adequately addressed. The aim of this study was to investigate the associations between patients' eating habits and optimal clinical response after MBS.
methodsThe study analyzed data from patients who underwent MBS at Marmara University Hospital between 2015 and 2023. Patient demographics, body mass index, obesity-associated medical problems, follow-up periods, surgical procedures (laparoscopic sleeve gastrectomy-SG, laparoscopic Roux-en-Y gastric bypass-RYGB), and eating habits (binge eating, carbohydrate craving, night eating, and sweet eating) were analyzed. Patients were divided into two groups: the optimal clinical response group (%TWL ≥ 20) and the suboptimal clinical response group (%TWL < 20) after surgery, and the groups were compared.
resultsA total of 426 patients, including 197 patients who underwent SG and 229 patients who underwent RYGB, were included. The mean age of all patients was 40.9 ± 10.7 years. During the preoperative period, binge eating, carbohydrate craving, night eating, and sweet eating habits were detected in 55.9%, 67.6%, 47.7%, and 60.6% of the patients, respectively. The mean follow-up period was 24 months (1-60 months). Eighty percent of the patients achieved an optimal clinical response. The preoperative eating habits and %TWL values of the patients were analyzed. There was no statistically significant effect of eating habits on the optimal clinical response in all patients or in the SG vs RYGB groups.
conclusionsThis study investigated the effect of preoperative disordered eating habits on weight loss after MBS and revealed no significant difference between those with these habits and those without these habits. It is difficult to predict weight loss after MBS on the basis of preoperative eating behavior. However, further studies are needed to evaluate this factor in combination with other factors before or after surgery.
