Obese and Pregnant: Is Rapid Weight Loss safe?

Sara

Is it safe for an obese woman? My current BMI is 34.8 (178 lb at 5') and my goal is 120lbs/23.4 BMI. I will be in a wedding come next May, and it will also be 6 months postpartum. Do I wait to lose most of my weight after the baby? I don't mind losing slower now since I know that's safe for me and the baby.
