Question 272 of 433
Should a healthy person take a GLP-1 medicine for longevity?
The short answer
If you have obesity, diabetes, or heart disease, these drugs extend healthy life and probably life itself. If you are lean and well, there is no trial to support it.
Semaglutide reduced heart attacks, strokes, and cardiac death by 20 percent in people with obesity and heart disease, slowed kidney failure, and improved heart failure, sleep apnea, and fatty liver. Those are longevity outcomes by any definition.
For healthy people, the “microdose” approach is unproven, and the costs are certain: possible lean-tissue loss, which includes more than skeletal muscle, and a need to protect nutrition and function, stomach side effects, expense, and probable weight regain on stopping. The largest trial in early Alzheimer’s disease was negative. See Part 11 for the details.
