B. thetaiotaomicron ameliorates obesity in mice by suppressing intestinal lipid absorption
we performed an intervention study in HFD-fed mice gavaged with either sterile PBS, live B. thetaiotaomicron (LBT), or heat-killed B. thetaiotaomicron (HKBT). Notably, mice receiving LBT exhibited a significantly reduced body weight gain compared to both PBS and HKBT groups.
