Hello and welcome !!
I can so relate to the holiday sabotage
Everyone is different so what I would do is check with your doctor first. You can't believe everything you read.
I don't know anyone who has maintained a lc diet while pregnant unless they had some medical reasons.
IMHO, babies need all the nutrients they can get, if I were to get pregnant again I would not be on any sort of restricted diet unless the doctor called for it. To me, a healthy baby is worth the weight I gain. I would eat a diet full of fruits, veggies, healthy whole grains, lean meats and stay away from the junk. Taking a prenatal vitamin is soooo important as well. But thats just MY opinion. Remember most of all, folic acid is SOOOOOO important to take even before you get pregnant as well as during your pregnancy.
HUGS TO YOU !!!!!!!
