Administration of specific probiotic strains (e.g., Lactobacillus gasseri SBT2055, L. curvatus HY7601, Akkermansia muciniphila) reduces body weight gain and visceral adipose tissue in high-fat diet-induced obesity models and some human trials, primarily through modulation of gut microbiota composition and energy homeostasis.

If you are overweight, adding specific probiotic strains (like L. gasseri or L. curvatus) to your routine may help reduce visceral fat and slow weight gain, especially if you eat a high-fat diet. However, this is not a universal fix; the strain matters significantly. It works best as part of a broader strategy including diet and lifestyle changes, rather than a standalone solution.

ModerateSupportsMEDIUM confidence
Convincing evidence from animal studies suggests that probiotic administration may reduce, at least in part, the amount of weight gained in response to a high-fat diet (HFD)... In recent multicenter, double-blind, placebo-controlled trial administration of fermented milk containing Lactobacillus gasseri SBT2055 for 12 weeks lead to significant reduction of abdominal visceral and subcutaneous fat areas... daily administration of A. muciniphila to HFD-induced obese mice for 4 weeks reduced body weight and improved body composition... with no changes in food intake

Why this rating

Strong preclinical evidence (animal models) but mixed/limited clinical evidence in humans; strain-specific effects vary.
