Across 3 studies (2 RCTs, 1 meta-analysis), 2 reported small beneficial effects of Lactobacillus gasseri BNR17 on reducing hip circumference in obese adults, while 1 found no effect. The predominant effect size is small, and the most commonly studied population is obese adults, though dose and duration data are incomplete.
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One study found no significant effect on hip circumference while two found small benefits, indicating possible inconsistency. Doses were not consistently reported, limiting dose-response conclusions.
The two groups had no special or severe adverse reactions.
