Take your body as a train, and the food you eat is the fuel that drives it. If the train runs smoothly and effectively, your food will be processed and the garbage "dispatched"
on time. However, if the train slows down, the garbage accumulates and becomes stopped at the station, resulting in a "traffic jam." Constipation, like a traffic jam, can cause your digestive system to slow down and make it difficult for waste to be expelled. And, just as a slow train may cause delays, a clogged digestive tract can cause weight gain.
