Effect of cocoa supplementation on body weight, body fat mass, and organ weight. a Body weights were determined over the course of 18 weeks. b The rate of body weight gain was calculated after cocoa supplementation (week 9–18). c Visceral fat mass and d gross organ weights were determined at the end of the experiment. Data were pooled from two identical studies (Experiment 1 and Experiment 2). LF, n = 35; HF, n = 44; and HF-HFC, n = 47. Values are expressed as mean ± SEM. Body weights were compared by two-way ANOVA with Bonferroni’s posttest (an asterisk indicates P < 0.05 compared to HF group). Mice body weights in LF group were significantly lower than HF mice since week 1. All other parameters were compared by one-way ANOVA with Dunnett’s posttest (an asterisk indicates P < 0.05 compared to HF-fed controls)
