The Claim

Daily supplementation with pasteurized Akkermansia muciniphila MucT for 24 weeks reduces weight regain by approximately 2.0 kg compared to placebo in adults with overweight or obesity who have previously lost at least 8% of their body weight, with mean weight regain of 1.2 kg in the intervention group versus 3.2 kg in the placebo group (P=0.012).

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In adults who lost at least 8% of their body weight, taking a daily supplement of pasteurized Akkermansia muciniphila MucT for 24 weeks resulted in 2.0 kg less weight regain compared to taking a placebo.

See the scientific wording

In adults with overweight or obesity who have previously lost at least 8% of their body weight, daily supplementation with pasteurized Akkermansia muciniphila MucT for 24 weeks reduces weight regain by approximately 2.0 kg compared to placebo, with a mean regain of 1.2 kg versus 3.2 kg in the placebo group (P=0.012), suggesting a probable causal role in maintaining weight loss after dieting.

Why this might work

After weight loss, the pasteurized bacteria interact with the gut lining and trigger changes in fat tissue that make it burn more energy instead of storing fat. At the same time, the bacteria reduce how much energy the body pulls from food, so more calories leave the body in feces. Together, these two effects create a sustained energy deficit that prevents weight from coming back.

  1. Study: Pasteurized Akkermansia muciniphila MucT for weight loss maintenance in people with overweight and obesity: a controlled randomized trial

    After losing weight, people who took a special pasteurized bacteria supplement regained 2 kg less than those who took a sugar pill, meaning the supplement helped them keep off more of the weight they lost.
