pregnancy weight gain

We can never underestimate the importance of balanced diet for our body. And when it comes to the diet during pregnancy, it is surely one of the major concerns for us. What we eat, how much we eat, purely affects our unborn child. But, with this “are we eating right?”, comes another question: “how much pregnancy weight gain is normal?”

Most of the times, you can trust on your appetite and taste for the food that your body wants. However, if you are obese, you should control your weight gain to limit the problems that you can face.

The process of your weight gain during pregnancy depends on a number of factors including your BMI (or the Body Mass Index, which is the measure of a person’s weight with respect to his/her height. Read more about it here), activity levels and genetics. The American College of Obstetricians and Gynecologists (ACOG) has given general guidelines on the pregnancy weight gain as per the BMI. The guidelines are as follows:

  • Women with a pre-pregnancy BMI under 18.5 should gain 28–40 pounds during their pregnancy
  • Normal-weight women with BMI in the range 18.5–24.9 should gain 25–35 pounds
  • Overweight women with their BMI in the range 25–29.9 should gain 15–25 pounds and,
  • Obese women with BMI 30 or more should gain only 11–20 pounds

Generally, it is recommended that during the first 3 months of pregnancy, women should gain only 1-4 pounds. Later, they can gain around 1 pound per week which can be achieved by consuming approximately 300 calories per day.

Weight gain during pregnancy is also attributed to a number of factors including size of the fetus, enlarged breasts, enlarged uterus, placenta, amniotic fluid, increased blood volume, increased fluid volume in the body and fat stores.
