"It's an irrational concept, yet an intriguing idea, that modern life so fills us with poisons from polluted air and food additives that we need to be periodically "cleaned out" ("detoxified").

Air pollution facts from the United States Environmental Protection Agency

Fine particles are easily inhaled deep into the lungs where they may accumulate, react, be cleared or absorbed.

Scientific studies have linked particle pollution, especially fine particles, with a series of significant health problems, including:

premature death in people with heart or lung disease,
nonfatal heart attacks,
irregular heartbeat,
aggravated asthma,
decreased lung function, and
increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing.

Fasting isn't going to get rid of particles in the lungs.
