Brief Summary

Recent data suggest that gut microbiota can function as an environmental factor that modulates the amount of body fat and obese individuals have an altered gut microbiota.The results of previous animal studies have suggest that a probiotic strain Lactobacillus paracasei K56 have reduced high-fat diet induced obesity. In this before-after pilot study, the participants were randomly assigned to 8 groups to compare the fat-reducing effect of the Lactobacillus paracasei K56 by continuously supplementing different product prototypes , and screen the best probiotic K56 prototype with the effect of fat reduction.
