After screening obese subjects who met the inclusion and exclusion criteria, the investigators randomly assigned the two treatment arms and one placebo arm at 1:1:1 ratio. At baseline, anthropometric and biochemical evaluations were conducted including body weight, body composition (DXA and Fat CT), lipid profiles, and liver function test. The tablets were supplied to each participants under double‐blind conditions. The investigators obtained blood and stool samples both baseline and final visit at 12 weeks.
