BACKGROUND: Cocoa and dark chocolate (DC) have been reported to be effective for health promotion; however the exact effect of cocoa/DC on anthropometric measures have not been yet defined.

METHODS: A comprehensive search to identify randomized clinical trials(RCT)s investigating the impact of cocoa/DC on body weight, body mass index (BMI) and waist circumference(WC) was performed up to December 2017. A meta-analysis of eligible studies was performed using random effects model to estimate pooled effect size. Fractional polynominal modeling was used to explore dose-response relationships for cocoa/DC supplementation.

RESULTS: A total of 35 RCTs investigated the effects of cocoa/DC on weight, BMI and WC were included. Meta-analysis did not suggest any significant effect of cocoa/DC supplementation on body weight (-0.108 kg,95% CI -0.262, 0.046 P = 0.168), BMI (-0.014 kg/m95% CI -0.105, 0.077, P: 0.759,) and WC (0.025 cm95% CI -0.083, 0.129, P = 0.640). Subgroup analysis revealed that that weight and BMI were reduced with cocoa/DC supplementation‚Č•30g chocolate per day in trials between 4-8 weeks. Chocolate consumption resulted in WC reduction in non-linear fashion (r = 0.042, P-nonlinearity = 0.008).

CONCLUSION: Cocoa/DC supplementation reduced body weight, BMI and WC. Dose and duration were important determinates for favorable effects on anthropometric measures.
