Applying User-Centered Design to Develop a Culturally Sensitive, Low-Calorie Meal Plan for Enhancing Dietary Behavioral Control in MASLD.
Article in Research square, 2025. 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
Background: Dietary changes are essential for managing metabolic dysfunction-associated steatotic liver disease (MASLD), yet patients often face barriers related to knowledge, skills, cost, time, and cultural fit. Aims: The purpose of this paper is to report a systematic, replicable method for culturally tailoring a dietary intervention and its application to create a calorie-restricted meal plan for Mexican and Central American patients with MASLD. Guided by the Theory of Planned Behavior and user-centered design, we produced a culturally tailored seven-day structured meal plan aligned with dietary guidelines for MASLD and weight loss. Methods: We conducted a three-phase, mixed-methods process among Mexican/Central American patients with MASLD from a safety-net healthcare system in Houston, Texas (n = 25). Phase 1 characterized meal patterns and preferences through semi-structured interviews. Phase 2 integrated findings with clinical nutrition guidelines to develop structured meal plan prototypes at 1200-, 1500-, and 1800-calorie levels. Phase 3 tested usability through ecological momentary assessments and daily interviews. Results: Participants typically consumed home-cooked meals centered on animal protein, legumes and simple grains, with lunch and dinner preparation being most challenging. Recipe modifications focused on increasing fiber and reducing fat and refined carbohydrates. Usability testing showed that participants found the plans culturally aligned and practical, improving portion awareness and dietary self-efficacy. Conclusions: This study demonstrates a replicable, patient-centered approach to culturally tailoring dietary interventions and provides a concrete product - a calorie- restricted meal plan. Next steps (underway) are to evaluate the meal plan's larger-scale implementation and impact on dietary change and weight loss.
