The minimum dietary preparation is seven days of strict adherence for someone already eating cleanly. Pork should stop two weeks before. Marijuana and recreational substances should stop one month before. Serotonergic medication washout is determined by the specific drug and must be managed with a prescribing doctor, typically four to six weeks or longer. For someone transitioning from a stimulant-heavy or processed-food diet, thirty days of clean living is a more honest preparation (Berlowitz et al., 2018).
