Calley Means on depression: what the evidence says · JRE #2210
SUBJECT: DEPRESSION

Study after study shows they have two courts of people. They've got people that exercise and eat whole foods, and then they have people that do antidepressants and go to therapy. The people that don't go to therapy, no drugs, but exercise and eat better food, demonstrably better outcomes
What the evidence says 01 / RECORD
Head-to-head evidence does not show exercise demonstrably beating antidepressants plus therapy. A systematic review and network meta-analysis of randomized trials in non-severe depression found no significant difference between exercise and antidepressants (standardized mean difference −0.12, 95% CI −0.33 to 0.10) and no treatment superior to another, though all beat controls, and exercise had higher dropout (relative risk 1.31). A large 2024 network meta-analysis (218 studies) reported that some exercise forms (walking or jogging, Hedges g −0.63) had point estimates numerically comparable to or larger than SSRIs alone (g −0.26) and CBT (g −0.55), but rated confidence in nearly all results as low to very low due to lack of blinding and high risk of bias, and positioned exercise alongside, not clearly above, medication and psychotherapy. So exercise appears roughly as effective as antidepressants for milder depression, but the claim that lifestyle without drugs or therapy produces demonstrably better outcomes than combined drug-plus-therapy care overstates what the trials show.
