First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a probiotic (Lactobacillus paracasei) or the drug semaglutide can help overweight or obese adults lose weight and improve metabolism. Over 12 weeks, 140 participants will follow a reduced-calorie diet and lifestyle program while taking one of these or a placebo. The goal is to see which approach works best for weight loss and long-term health.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Lactobacillus paracasei LC-19 (a probiotic) and semaglutide (a weight-loss drug)

What this could lead to

If successful, this could show that a specific probiotic helps with weight loss and metabolic health, offering a natural alternative or complement to drugs like semaglutide.

What could go wrong

This is a small, early-stage trial (140 people) with no phase designation. Results may not apply to everyone, and probiotics often have modest effects. Side effects or lack of long-term benefit are possible.
