I'm between 4 and 5 months out, and for me, I don't get hungry yet. However, if I haven't eaten in a long time, I have a vaguely gross/ slightly nauseated feeling that reminds me to eat something. Then I feel better.
Temporarily holding on losing more because I'm gaining! Pregnant with my first baby (a boy!) due June 2013, after two rounds of IVF. SO GRATEFUL!
