A common, erroneous explanation for why we weigh less in the morning is that the undigested food eaten throughout the day is absorbed into the body during sleep. The problem with this theory is that it fails to explain where the mass goes; once a meal is digested, it is still in the body. The correct explanation is that we lose water weight through breathing and sweating. Also, we constantly breathe out carbon dioxide, and the mass from the released carbon adds up throughout the night. A combination of breathing, sweating, and releasing carbon, therefore, makes us lighter in the morning.
