Question

Quizplus · Accepted Answer

Laxatives primarily act on the large intestine, where they expedite the movement of the intestinal contents. However, most nutrient absorption occurs in the small intestine. By the time the digested food reaches the large intestine, most calories have already been absorbed. Therefore, using laxatives affects water and mineral absorption more than it does calorie absorption, making them ineffective for weight loss.
