Does probiotic supplementation aid weight loss? A randomized, single-blind, placebo-controlled study with Bifidobacterium lactis BS01 and Lactobacillus acidophilus LA02 supplementation.
Trial report in Eating and weight disorders : EWD, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeProbiotic supplements are gaining popularity worldwide. This trend is especially present in females, and a common motivation for consumption is weight loss, no matter the BMI. The aim of this study was to investigate the effects of probiotic supplementation on weight loss in healthy, young adult females and to put claims made by manufacturers of such products to the test.
methodsThe study utilizes a randomized, single-blind, placebo-control design. 53 females aged 19-33 were enrolled, and 38 completed the trial. A 6 week supplementation with Bifidobacterium lactis BS01 and Lactobacillus acidophilus LA02 or placebo was conducted. Anthropometric measures (body mass, BMI, body fat percentage, arm skinfold fat, waist circumference, and WHR) were applied pre and post-treatment.
resultsNo significant changes in anthropometric measures were observed in both supplementation and placebo groups.
conclusionThe results of this investigation do not support claims made by probiotic products manufacturers, that they aid weight loss. Our results seem to support an argument that weight loss is mostly associated with food habits and dietary behaviors, not probiotic intake. It is possible that probiotic supplementation may play a facilitating weight loss but has no effect without dietary intervention. Another possible explanation is that due to strain specificity-bacteria strains used in this study are not effective for weight loss. LEVEL OF EVIDENCE: I: randomized controlled trial.
