Salted Peanuts. While peanuts won't necessarily cause you to gain fat, the salted variety can contribute to temporary water weight gain when they are part of a high-sodium diet. An extra 400 milligrams of sodium leads to 2 pounds of water weight -- and a serving of salted peanuts has almost 200 milligrams of sodium.
Castor Oil starts the diarrhea two to six hours after drinking the oil. The contractions should begin shortly after that. Some midwives and mothers swear on this method and have repeatedly used this to conclude an overdue pregnancy.
It works well because castor oil is used as a natural laxative so when taken in larger amounts it will contract your bowels which will then upset your uterus into contracting. This, though, will only work if you are close to labor and your body is ready for it.
