Understanding Participants' and Health Professionals' Perceptions and Experiences of Time-Restricted Eating: A Systematic Review of Qualitative Evidence.

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
backgroundTime-restricted eating (TRE) limits food intake to a specific daily window and has gained popularity, showing modest benefits for cardiometabolic health. However, perspectives and experiences from adults and healthcare professionals about TRE remain underexplored but are vital for successful implementation in research and clinical practice.
objectiveTo synthesize qualitative evidence on participants' and healthcare professionals' experiences and perceptions of TRE, with a gender-based analytical lens.
methodsA systematic search was conducted on four databases from their inception until March 2025, searching for studies reporting qualitative analysis of the perceptions and experiences associated with TRE in adults and healthcare professionals. Methodological quality was appraised using the CASP checklist. Thematic synthesis was applied to extract overarching themes, with additional gender-based analysis. Confidence in the findings was assessed using the GRADE-CERQual approach.
resultsThirteen articles including 225 participants (aged between 18 and 74 years), of which 22 were health professionals and dietitians were included. Three themes were found: motivation; barriers and facilitators, including three subthemes in each: biological, psychological and socio-cultural. Women's perspectives were commonly related to disappointment with previous diet and body dissatisfaction as motivators, food craving and emotional eating behaviors as barriers, and improvement of healthy eating habits and hunger control as facilitators. Otherwise, men were more motivated by managing appetite with shorter eating windows and found routine and day planning as key facilitators.
conclusionPerceptions and experiences of TRE are shaped by diverse motivators and challenges. Tailored, gender-sensitive approaches to support TRE integration in clinical practice are needed. PROSPERO Registry Number: CRD420250649633.
