PURPOSE: An antiobese composition and food including the same are provided to be effectively used in suppressing obesity as the composition showed an anti-obesity effect when used in mice. CONSTITUTION: An antiobese composition is an extract that is manufactured by mixing 25 to 35 wt% of Coix lacryma-jobi, 10 to 20 wt% of Poria cocos, 5 to 15 wt% of glycyrrhizae radis, 15 wt% of Carthamus tinctorius, and the rest portion of Cinnamomum loureirii, adding the mixture in refined water of 5 to 20 times the weight of the mixture, heat-extracting the mixture at a temperature of 90 to 110>;= for 1 to 3 hours, and filtering the resultant.
