Losing the remainder of my baby weight

Yay!! Today is the first day of my diet officially, its currently 5:26pm and I am starving. The diet I am doing is the special K diet and thus far it has been ok. ith this particular diet you can eat one REAL meal a day-- today I am choosing dinner for that. I am 24 years old and 5'10", I weigh 175 and want to drop 15 lbs and get to 160. This is all new to me because before I had my child (she is 18 months) I never had any sort of struggle with my weight...and now I cant seem to get this last few off, so here I am. Wish me luck.
