Objective　Lactobacillus gasseri（L. gasseri）SBT2055 inhibits dietary fat absorption in rats, and exerts preventive effects on abdominal adiposity in both rats and humans. We evaluated the effects of the L. gasseri SBT2055 on body fat accumulation in obese subjects.
Methods　Volunteers（n＝101；54 male, 47 female；BMI of 25 to 30 kg/m²）were given 100 g of fermented milk containing L. gasseri SBT2055（10⁷ cfu/g）or placebo daily for 12 weeks.
Results　After 12 weeks, abdominal visceral fat area in the test sample group was significantly reduced compared with the placebo group.
Conclusions　These results indicated that SBT2055-fermented milk reduces the abdominal adiposity including visceral fat.
