Dose-dependent effect of coconut oil supplementation on obesity indices: a systematic review and dose-response meta-analysis of clinical trials.
Synthesis in BMC nutrition, 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
backgroundCoconut oil has been suggested as a potential dietary intervention for weight management. However, the evidence regarding the effects of coconut oil supplementation on anthropometric measures (body weight, body mass index (BMI) and waist circumference (WC)) remains inconclusive.
objectivewe aimed to assess the overall effect of coconut oil supplementation on these anthropometric parameters and explore potential sources of heterogeneity.
methodsWe comprehensively searched electronic databases using appropriate keywords. We included 15 studies with the following criteria: (1) clinical trials in adults, with parallel or cross-over design, (2) evaluated the effect of coconut oil on body weight, BMI or WC, (3) compared the effect of a specific dose of coconut oil against a coconut oil-free diet or other types of oils, (4) considered the change in anthropometric parameters as the primary or one of the secondary outcomes, (5) provided mean and standard deviation (SD) of change in anthropometric parameters across study arms, (6) reported the number of participants in each study arm.
resultsThe trials included 620 participants and assessed the effects of coconut oil supplementation on body weight, BMI and WC. Our meta-analysis revealed statistically significant effects of coconut oil supplementation on weight and BMI, with mean differences of 0.04 kg (95% CI: 0.01 to 0.08 kg) and 0.01 kg/m2 (95% CI: 0.00 to 0.02). However, the effects were not clinically meaningful. There was no significant effect of coconut oil on WC. Subgroup analyses suggested that the duration of the intervention may influence the effect of coconut oil on body weight. In the sensitivity analysis, we found that the result of one study influenced the associations between coconut oil supplementation and weight or BMI.
conclusionsOverall, our findings suggest no clinically significant effects of coconut oil supplementation on weight loss. Further research is needed to clarify the issue. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD420251031291.
