Structured higher protein meal replacement plans for weight loss and metabolic health: A qualitative narrative evidence review of Medifast interventions.
Review in Obesity pillars, 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
Background: Excess body weight and impaired metabolic health increase chronic disease risk, necessitating effective weight management strategies. Commercial weight loss programs are widely used, but impact on body composition and cardiometabolic markers requires evaluation. The objective of this narrative review was to assess the efficacy of Medifast's structured higher protein meal replacement plans with comprehensive lifestyle intervention. Methods: In this narrative qualitative evidence review, publications (2010-2025) utilizing Medifast meal plans (800-1000/80-120; 1100-1300/120-150; 1300-1500/140-170 kcal/g protein/day) as a weight loss intervention were identified Results: Seventeen publications representing nine unique randomized controlled trials (RCTs) and additional secondary analyses and chart reviews were included (n = 20-816; 4-26 weeks duration). Participants were adults living with overweight/obesity, including older adults and those with coexisting conditions (e.g., post-prostatectomy, post-ischemic stroke). Thirteen of 14 studies reported clinically meaningful weight loss (≥5%) with 7 reporting ≥10%. Total fat mass (FM) was significantly reduced in all reporting studies (3.2-11.0 kg; 11/11 studies; Conclusions: Medifast's structured, higher protein meal replacement plans with comprehensive lifestyle interventions yield clinically meaningful short-term weight loss and favorable body composition changes; cardiometabolic outcomes vary. While long-term durability data are needed, clinicians may consider these plans as options for the dietary foundation within the obesity care framework, tailored to individual patient needs.
