A greater reduction in BMI was found with multiple species of probiotics .
Consuming probiotics  could reduce body weight and BMI , with a potentially greater effect when multiple species of probiotics were consumed , the duration of intervention was ≥8 weeks , or the objects were overweight
OBJECTIVE To assess the efficacy of probiotic therapies on body weight and BMI  using a meta- analysis of r and omized , controlled trials .
Regulation of abdominal adiposity by probiotics (Lactobacillus gasseri SBT2055) in adults with obese tendencies in a randomized controlled trial
Background / Objectives : In spite of the much evidence for the beneficial effects of probiotics , their anti-obesity effects have not been well examined . We evaluated the effects of the probiotic Lactobacillus gasseri SBT2055 ( LG2055 ) on abdominal adiposity , body weight and other body measures in adults with obese tendencies . Subjects/ Methods : We conducted a multicenter , double-blind , r and omized , placebo-controlled intervention trial . Subjects ( n=87 ) with higher body mass index ( BMI ) ( 24.2–30.7 kg/m2 ) and abdominal visceral fat area ( 81.2–178.5 cm2 ) were r and omly assigned to receive either fermented milk ( FM ) containing LG2055 ( active FM ; n=43 ) or FM without LG2055 ( control FM ; n=44 ) , and were asked to consume 200 g/day of FM for 12 weeks . Abdominal fat area was determined by computed tomography . Results : In the active FM group , abdominal visceral and subcutaneous fat areas significantly ( P<0.01 ) decreased from baseline by an average of 4.6 % ( mean ( confidence interval ) : −5.8 ( −10.0 , −1.7 ) cm2 ) and 3.3 % ( −7.4 ( −11.6 , −3.1 ) cm2 ) , respectively . Body weight and other measures also decreased significantly ( P<0.001 ) as follows : body weight , 1.4 % ( −1.1 ( −1.5 , −0.7 ) kg ) ; BMI , 1.5 % ( −0.4 ( −0.5 , −0.2 ) kg/m2 ) ; waist , 1.8 % ( −1.7 ( −2.1 , −1.4 ) cm ) ; hip , 1.5 % ( −1.5 ( −1.8 , −1.1 ) cm ) . In the control group , by contrast , none of these parameters decreased significantly . High-molecular weight adiponectin in serum increased significantly ( P<0.01 ) in the active and control groups by 12.7 % ( 0.17 ( 0.07 , 0.26 ) μg/ml ) and 13.6 % ( 0.23 ( 0.07 , 0.38 ) μg/ml ) , respectively . Conclusion : The probiotic LG2055 showed lowering effects on abdominal adiposity , body weight and other measures , suggesting its beneficial influence on metabolic disorders
