A low-protein diet drives short- and long-term improvements in metabolic health in a mouse model of sleeve gastrectomy.

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
Despite the beneficial impact of bariatric surgery on obesity and metabolic disease, continued post-surgical obesity and weight recurrence are common, but may be impacted by diet. While guidelines recommend a post-operative high-protein diet to preserve lean mass, emerging evidence suggests that humans and mice are metabolically healthier on low-protein diets. Here, we assess the effect of varying dietary protein on post-surgical metabolism in a mouse model of sleeve gastrectomy. We find that a low-protein diet optimally drives post-surgical weight loss, boosts energy expenditure, and improves blood glucose regulation, likely, in part, due to the induction of FGF21. Through multi-omics, we identified clusters of differentially expressed genes and metabolites that correlate with these phenotypes and find that diet heavily influences the liver's molecular response to sleeve gastrectomy. These results suggest that current post-surgical high-protein diets may limit the short- and long-term benefits of surgery and warrant human clinical trials.
