The amounts of weight that women gain during pregnancy vary widely. When you eat well, your weight will take care of itself. Pregnancy is not a time to diet. In fact, it is important that you gain enough weight so that your baby can grow to a healthy weight.
Women who enter pregnancy at an average weight usually gain between twenty and thirty five pounds. If you are underweight, you may gain more; if heavier, you may gain less. To help maintain your own healthy weight, balance the amount of food you eat with your activity levels and your body's needs.
