Promising Gut Microbe May Aid in Weight Maintenance
A new study suggests that a gut microbe could support people in keeping off the weight they’ve lost. The research, published in Nature Medicine, focused on Akkermansia muciniphila MucT, a non-live bacterium that may play a role in weight maintenance.
Study Overview
The study involved 90 overweight and obese adults from the Netherlands who participated in an eight-week low-calorie diet, aimed at losing 8% of their body weight. After the diet, participants entered a 24-week maintenance phase, during which they were divided into two groups: one took the gut bacterium, and the other received a placebo.
Key Findings
Results showed that those taking Akkermansia regained significantly less weight compared to the placebo group—about 2.6 pounds versus 7.1 pounds. Researchers noted that the effectiveness of this treatment could depend on individuals’ existing gut bacteria, and no serious side effects were reported during the study.
Expert Insights
Dr. Peter Balazs, a hormone and weight loss specialist from New York and New Jersey, praised the study as “well-designed.” He highlighted that Akkermansia stands out because it’s not a standard live probiotic, but works through specific components that help support gut health.
“This protein strengthens the gut barrier, reduces inflammation, and aids metabolic health,” Dr. Balazs explained. He pointed out that while this gut microbe could help combat natural weight regain after dieting, it shouldn’t be seen as a “magic solution.”
Limitations
While results are promising, Dr. Balazs emphasized that Akkermansia should not replace diet, exercise, or medical guidance. He noted that the study’s short duration and modest size may limit its findings. Moreover, participants were allowed to eat freely, which could affect outcomes.
Conclusion
The findings on Akkermansia muciniphila provide hope for individuals looking to maintain their weight. However, more research is needed to confirm these benefits in the long term.
