Eating for Appropriate Weight Gain During Pregnancy
Some women may think of pregnancy as their ticket to eat anything they want, indulging any and all cravings and leaving portion control by the wayside. Put aside the thought you are eating for 2. It may sound ideal, but that kind of thinking is not an ideal way to approach nutrition when making food choices during pregnancy. Both inadequate weight gain and excess weight gain during pregnancy pose risks to both mother and child. A balanced diet can help you maintain a healthy weight and provide the best nutrition for you and your unborn baby. The following guidelines can help you find a nutrition balance for your pregnancy.
Guidelines for Weight GainExactly how much weight gain to aim for will vary among women and depends on several factors, including the mother’s pre-pregnancy weight, height, age, and health status, as well as whether or not the pregnancy will involve twins, triplets, or more. See your doctor to determine the best weight gain goal for you. In general, the following Institute of Medicine and National Research Council guidelines are used for women with a single-baby pregnancy:
- Women beginning pregnancy at a normal weight (defined as body mass index [BMI] of 18.5-24.9) are advised to gain 25-35 pounds during pregnancy.
- Underweight women (BMI 18.4 or less) are advised to gain 28-40 pounds.
- Overweight women (BMI 25-29.9) are advised to gain 15-25 pounds.
- Obese women (BMI 30 and over) are advised to gain 11-20 pounds.
