Ultra-processed Food Consumption After Metabolic and Bariatric Surgery: Implications for Recurrent Weight Gain, Dietary Quality, and Nutritional Outcomes - A Narrative Review.
Review in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Ultra-processed food (UPF) intake is increasingly linked to poor dietary quality, but its course after metabolic and bariatric surgery (MBS) is unclear. This narrative review synthesized 12 observational reports (7 independent datasets) on postoperative UPF consumption and its associations with weight outcomes, dietary quality, and nutritional status. UPF intake fell early after surgery but rebounded from 12 to 24 months, approaching preoperative levels by year 5. Higher intake was associated with lower total weight loss, poorer dietary quality, and lower protein and micronutrient intake, whereas associations with recurrent weight gain were inconsistent and partly reflected total energy intake and processed foods. The evidence was limited and mostly cross-sectional. UPF consumption is a modifiable target for nutritional monitoring beyond the first 2 postoperative years.
