Results: The meta-analyzed mean differences for random effects showed that cholecalciferol supplementation deceases the BMI by −0.32 kg/m2 (CI95% −0.52, −0.12 kg/m2, p = 0.002) and the waist circumference by −1.42 cm (CI95% −2.41, −0.42 cm, p = 0.005), but does not statistically affect weight loss −0.43 kg (CI95% −1.05, +0.19 kg, p = 0.17). Conclusions: This meta-analysis lays the foundation for defining the potential clinical efficacy of vitamin D supplementation as a potential therapeutic option for weight loss programs, but further studies are needed to confirm the validity of these findings and delineate potential underlying mechanisms.
