Probiotic May Help Lower Body Fat in Pre-Obese People
Obesity is a growing problem worldwide, and previous research has found a link between gut microbiota and the development of obesity. A recent study suggests that dietary supplementation with the probiotic Bifidobacterium breve B-3 may help lower body fat levels in healthy, pre-obese individuals.
Participants in the study included 80 pre-obese but healthy Japanese adults who were given either 20 billion CFU of B. breve B-3 or a placebo daily for 12 weeks. All had a BMI between 25 and 30.
The researchers noted significant increases in visceral fat in the placebo group at both four and eight weeks. There were no significant changes in the probiotic group. They also noted significant changes in percent body fat and body fat mass in the supplement group at weeks 8 and 12. By the end of the study, the supplement group had an average 0.6 kg reduction in body fat mass and 0.7% reduction in percent of body fat.
The researchers did not note any significant differences in blood markers between the two groups. They did, however, note slight decreases in triglycerides and increases in HDL cholesterol levels in the supplement group, when compared with baseline.
Researchers from Morinaga Milk Industry Co. in Japan conducted the study. It was published online ahead of print on May 8, 2018, in Bioscience of Microbiota, Food and Health.
