Oral administration of live Parabacteroides goldsteinii reduces obesity, improves insulin sensitivity, and enhances thermogenesis in high-fat diet-fed mice.

This study suggests that Parabacteroides goldsteinii is a beneficial gut bacterium that can help reduce obesity and improve metabolic health. While you cannot currently buy this specific strain as a commercial probiotic supplement, the findings highlight the importance of supporting beneficial gut bacteria through diet (prebiotics) to potentially improve metabolic health.
