First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a probiotic called Akkermansia muciniphila can help overweight and obese adults lose weight and improve their metabolism. Over 12 weeks, 76 participants will take either the probiotic or a placebo, while following a low-carb diet. Researchers will measure changes in body weight, body fat, and blood fats like cholesterol.

- What this could lead to
- If it works, this could point toward a natural supplement to help with weight loss and better metabolic health in overweight adults.
- What could go wrong
- This is a small, early-stage trial with only 76 people. The probiotic may not cause significant weight loss, and results may not apply to everyone. No serious risks are expected, but digestive discomfort is possible.
