Another possibility is that the heavier a person is, the more liver enzymes they have to clear medications from the body, causing a drop in circulating blood levels of the drug. A third theory is based on the fact that the active ingredients in oral contraceptives – the hormones estrogen and progesterone – are stored in body fat. "The more fat a person has, the more likely the drug is sequestered, or trapped, in the fat instead of circulating in the bloodstream," (epidemiologist Victoria) Holt said.
