I agree with the opinion of not worrying about it until you are done breast feeding, as breast feeding helps the body recover as well as is the best nutrition for your child. Once you are done with that, then get on a clean eating program. Dump the slim-fast shakes immediately. They are FULL of sugar. They are all marketing and no help, IMHO. I started a clean eating lifestyle back in January, and I am down 18 pounds since then, and feel fantastic. It's quite amazing how much better you feel when the stuff you are putting into your body is good. There is a lot of info on the net about clean eating. Ours (my wife and mine) is very similar to a paleo style diet.
