AI Summary

A small trial found that a daily postbiotic supplement containing dead bacteria increased levels of the appetite‑suppressing hormone GLP‑1, which may help people lose weight. The study suggests the supplement could offer a cheaper, more convenient alternative to GLP‑1 drugs such as semaglutide, or help maintain weight loss after those medications are stopped. GLP‑1 drugs are widely used for weight loss but many patients discontinue them within a year because of high costs, shortages and side effects like nausea, vomiting and stomach pain.
