Quick answer

Bottom line

Not competitors. Lifestyle medicine is the soil; ketamine is a tool that works far better in well-prepared soil. Treat them as complementary.

This page compares Ketamine and Lifestyle medicine across the same fixed dimensions - mechanism, evidence, onset, duration, side effects, access, suitability, and limits. It does not name a winner and does not recommend either option for you.
