SouthernWorldwide.com – A new study suggests that a specific type of gut microbe might hold the key to achieving long-term weight loss goals.
Researchers investigated whether a pasteurized gut bacterium, known as Akkermansia muciniphila MucT, could assist individuals in maintaining their weight after shedding pounds. The findings were published in the journal Nature Medicine.
The study involved 90 adults from the Netherlands who were classified as overweight or obese. For eight weeks, they followed a low-energy diet designed to help them lose approximately 8% of their body weight.
Following the initial weight loss phase, participants entered a 24-week weight maintenance period. During this time, they were randomly assigned to receive either the gut bacterium or a placebo.
The results indicated a significant difference in weight regain between the two groups. Those who received Akkermansia regained an average of 2.6 pounds, while the placebo group regained an average of 7.1 pounds. This difference was deemed statistically significant.
The researchers also noted that the effectiveness of this treatment appears to be influenced by an individual’s existing gut microbiome composition. Importantly, no serious adverse events were reported during the study.
However, the study team acknowledged certain limitations. The relatively short duration and the small number of participants might not be sufficient to confirm long-term benefits. Additionally, participants were allowed to eat whatever they chose during the maintenance phase, rather than adhering to a standardized diet.
Dr. Peter Balazs, a specialist in hormones and weight loss based in New York and New Jersey, described the trial as “well-designed.” He highlighted that pasteurized Akkermansia is not a live probiotic but functions through its components, particularly a protein called Amuc_1100.
According to Dr. Balazs, this protein plays a crucial role in strengthening the gut barrier, reducing low-grade inflammation, and supporting healthy metabolic functions. He explained that after weight loss, the body naturally tends to regain fat. Akkermansia appears to help mitigate some of these biological signals, thereby making it easier to sustain weight loss results over time.
While these findings are encouraging, Dr. Balazs cautioned that Akkermansia should not be viewed as a “miracle pill.” He clarified that its benefit lies in aiding weight maintenance rather than initiating weight loss. The long-term efficacy beyond 24 weeks remains unproven.
He further emphasized that this intervention does not substitute for established strategies like diet, exercise, or professional medical advice.
