Does my PCF Target change through the course of my pregnancy? My goal is to keep body fat to a minimum without affecting the health of my baby.

It's good to hear you say that the health of the baby is a priority over vanity. Remember you can always do a little work in getting back into shape after she or he is born, but you can't turn around your baby's health as easily if you (and the baby) have not been properly nourished during pregnancy.

During pregnancy you do have a need for more protein. The physical structure of a 3.5kg baby requires on average an extra 20g of protein for each day of pregnancy.

Over and above that, you as a mother need extra protein to (internally) support the baby and increase your strength for carrying the baby. I recommend an increase of protein of between 30g and 40g per day.

There is also increased need for calcium and many other micro-nutrients. Essential fatty acids (such as those from linseed, fish oils, avocado, olive oil) also need to increase by about 10g a day.

If you are getting the protein and EFAs (essential fatty acids) right, you probably will not need extra carbs. Therefore you are less likely to store too much fat.
