Congratulations to the royal family on the birth of the royal baby.

Kate Middleton (or should I say The Duchess) is an excellent example of how much weight a woman should gain when pregnant.  Here are a few important notes for pregnant women to remember:

You are NOT eating for two. It is a myth! A pregnant woman only needs about 300 extra calories a day.

The weight gain during pregnancy provides nutrition to your developing baby and is also stored for breastfeeding after your baby is born.

Weight gain in pregnancy is based on your pre-pregnancy weight.

If you are “normal” weight then you only should gain about 25-35 pounds.

If you are underweight, you should gain around 28 to 40 pounds.

If you are overweight or obese then you may only need to gain around 10- 15 pounds.

Where does all the weight gain go?

The average weight of a full term baby in the US is 7 pounds, the placenta weighs about 2 pounds, the amniotic fluid (the fluid around the baby) weighs about 2 pounds, a woman’s blood volume doubles when she is pregnant and this accounts for about 4 pounds of weight gain, breast gain is about 2 pounds, and finally, a woman’s body will retain fat, fluid, and nutrients in order to breast feed the baby when it is born, this accounts for most of the weight gain, which is about 10 pounds.

Add up all those numbers and you get 27 pounds. Voila!

Any additional weight gain is just that: weight gain or fat.   The more excess weight gained during pregnancy, the harder it is to lose after pregnancy.

Breast feeding is the best way to lose the pregnancy weight and the best thing for your baby.

I am sure within 2 months we will see a lean new mother in Buckingham palace. (Way to go Kate!)
