During pregnancy, women often change their eating styles to support fetus's growth. Postnatal nutrition is often important, especially for breast-feeding women. But if not handled properly, postnatal body weight can easily increase.
In order to prevent postnatal weight gain, you should focus on vegetables, fruits and whole-grain foods. You should also avoid or limit high-fat and high-calorie foods.
Proper postnatal workout is also important, because it helps women restore and maintain a healthy body weight. But first you should consult your doctor, and see whether you can begin a postnatal workout.
