                                A 2016 systematic review found that while many probiotic strains aid in weight loss, *Lactobacillus gasseri* L66-5 was observed to promote weight gain in experimental models. This highlights a crucial but often overlooked detail about probiotics: their effects are highly dependent on the specific strain.
