Background: Only few studies have investigated the role of probiotics in the development of obesity. We aimed to determine the efficacy and safety of an intake of K50 () on body fat and lipid profiles in people with obesity.

Methods: This randomized, double-blind, placebo-controlled, clinical trial involved 81 adults with a body mass index of 25-30 kg/m who were assigned randomly to a diet including 4 × 10 colony-forming unit of or a placebo. Changes in body fat, anthropometric parameters, and biomarkers of obesity were compared using a linear mixed-effect model.

Results: After 12 weeks of treatment, body weight, fat mass, and abdominal fat area did not change significantly in the two groups. However, total cholesterol levels decreased from 209.4 ± 34.4 mg/dL to 203.5 ± 30.9 mg/dL in the group, but increased from 194.7 ± 37.5 mg/dL to 199.9 ± 30.7 mg/dL in the placebo group (P = 0.037). Similarly, triglyceride levels decreased from 135.4 ± 115.8 mg/dL to 114.5 ± 65.9 mg/dL in the group, with a significant difference between groups. supplementation also tended to decrease leptin levels compared with placebo. It also changed the distribution of gut microbiota significantly, with an increase in and a decrease in , both of whose changes in abundance were correlated with changes in visceral adiposity, with borderline significance.

Conclusion: A 12-week consumption of reduced the total cholesterol and triglyceride levels significantly with favorable alterations in microbiota, suggesting potential benefits for controlling blood lipid profiles.
