Sure, anything can be a placebo effect. However I myself prefer to understand exactly what is happening rather than believing fairy stories, and I think it's fairer to patients as well. Unfortunately there is a lot of dubious science out there, and a lot of patients who prefer the fairy stories. Having said that, doing things like exercising and having a good diet will certainly improve health. Exercise has proven to be very beneficial for depression, although I don't think that inflammation has been proven to be what mediates the effect.
