- Treated mice ate 24% less, lost weight, and showed better physical health and slower aging signs.
- GLP-1 drugs reduce hunger by mimicking a natural hormone that makes people feel full and slows digestion.
- About 1 in 8 Americans used GLP-1 drugs in March 2026, coinciding with a decline in obesity rates.
- Experts say the results in mice are promising but translating this to humans is more complex and requires safety checks.
- Some benefits might come from reducing calorie intake, improving heart health, and lowering inflammation.
