Hidden Malnutrition in the GLP-1 Era: Micronutrient Status, Protein Adequacy, and Lean Mass as Emerging Nutritional Considerations-A Narrative Review.
Review in Nutrients, 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
Glucagon-like peptide-1 (GLP-1) receptor agonists and dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 receptor agonists have transformed obesity management by producing substantial, sustained weight loss and improving metabolic health. Alongside these benefits, their effects on appetite, food intake, and gastrointestinal function have raised increasing interest in the nutritional consequences of pharmacologically induced weight loss. Although reductions in energy intake contribute to therapeutic efficacy, they may also influence protein intake, dietary quality, micronutrient adequacy, and skeletal muscle health, particularly in individuals with pre-existing nutritional vulnerability. This narrative review summarizes current evidence regarding nutritional considerations during GLP-1-based therapy, including changes in dietary intake, protein and micronutrient adequacy, body composition, muscle health, and nutritional assessment. Particular attention is given to populations at increased nutritional risk, practical approaches to nutritional monitoring, and strategies to support adequate nutrition during treatment. Current evidence suggests that nutritional responses to GLP-1-based therapy are heterogeneous and cannot be adequately evaluated using body weight alone. Assessment of dietary intake, body composition, muscle function, physical performance, and individual clinical characteristics provides a more comprehensive understanding of nutritional status than anthropometric measures alone. While routine supplementation or intensive monitoring is not supported for all patients, a risk-based and individualized approach appears appropriate, particularly for older adults and individuals with sarcopenic obesity, previous bariatric surgery, chronic gastrointestinal disease, or persistent treatment-related gastrointestinal symptoms. Future research should establish clinically meaningful nutritional outcomes and determine which nutritional interventions improve patient-centered outcomes during long-term obesity management.
