Some doctors advise their patients to lose weight before attempting to
get pregnant. Other doctors simply recommend that patients maintain a

You may not gain as much weight over the course of your pregnancy as a
thin person might. However, it is a very bad idea to deliberately try

these things for thin women's babies.
