Question 152 of 433
Should a lean, healthy person “microdose” a GLP-1 for longevity?
The short answer
The evidence does not yet justify it.
This idea is popular, and I have written about it with more enthusiasm than I would today. The reasoning is that these drugs lower inflammation and protect the heart and kidneys beyond their effect on weight, so a small dose might help anyone. It is a reasonable hypothesis. But every outcome trial so far enrolled people with obesity, diabetes, heart disease, or kidney disease. In lean, fit people we have no trial, and the known costs, including gastrointestinal side effects, expense, and possible loss of lean tissue, are real. Their likelihood and severity vary, and the clinical benefit in this population remains unproven.
If you have metabolic disease, these are among the most important medicines of our time. If you do not, wait for the data.
