The impact of short-term intensive fasting on physical health and gut microbiota in obese individuals.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Objectives: This study aimed to characterize how a 7-day complete water-only fast followed by structured refeeding was associated with changes in body weight, hydration-dependent bioelectrical-impedance estimates, physical test performance, cardiovascular indicators, and gut microbial ecology in adults with obesity and normal-weight controls. Methods: Seventy-two eligible volunteers formed prespecified BMI sampling strata (normal weight, Results: BMI-group-by-time interactions were significant for body weight and BMI (both Conclusion: Supervised seven-day water-only fasting followed by structured refeeding was associated with reduced body weight, particularly in participants with obesity. Changes in body composition were BIA-derived estimates, while higher dynamometer scores represented measured test performance that may have been influenced by familiarization. Gut-microbiota alpha diversity was largely stable, with exploratory compositional changes supporting further investigation in controlled studies.
