Introduction: Several studies have demonstrated Hibiscus sabdariffa L administration effects on weight reduction in experimental models. The aim of this study was to evaluate the administration of an aqueous infusion prepared from calyxes Hibiscus sabdariffa L on body mass index, appetite and satiety in type I obese individuals. Materials and Methods: 30 adults with obesity type 1 were randomly assigned to receive an infusion of Hibiscus sabdariffa L or placebo during 3 weeks twice daily. Ponderal evaluation was performed using BMI and the effect of administration of treatment/placebo on appetite and satiety sensation was assessed by visual analog scale (VAS). Qualitative variables were expressed as absolute and relative frequencies and continuous variables as mean ± SD. Student´s t test was performed for differences between means and intragroup comparisons according time (week 1, 2 and 3) was assessed by repeated measures ANOVA´s test (GLM). Results: The individuals treated with Hibiscus sabdariffa L infusion exhibited a significant BMI reduction when compared with those receiving placebo. No significant differences were found in appetite and satiety between placebo and Hibiscus-treated group in any week studied. Conclusions: We demonstrated a short-term reduction in BMI by Hibiscus sabdariffa aqueous infusion administration in type I obesity individuals not related to appetite or satiety changes. A possible thermogenic effect could explain this weight reduction.
