i saw something on the Today Show (don't ask me why i was watching) that said you have to lose the baby fat within 3 months of having the baby. the hormones in your body will help you get back in shape. but after the 90 days, it's not gonna be easy.
i know that's not really relevant info. i just thought i'd put it out there for other expecting moms.
btw amanda, way to go!! 68 lbs is a lot of weight to lose. if 115 is your goal, and you want to keep the weight off, maybe you should think about putting on a little muscle. maybe be even more healthy than you were before you had your son. lean muscle uses a lot of energy, even at rest. it will raise your metabolism and make it less likely that you'll gain back fat that you've lost.
heavy dieting not only reduces fat, but can also reduce muscle mass. make sure you're eating a lot of protein!
