Welcome! I'm like you; I definitely want to know how long will it take me to lose the weight and be a whole new me! But I'm trying to look at things differently and just make small changes I can live with forever. I don't want to feel like I'm on a diet forever, but I'd like to be healthy forever! Be good to yourself and don't push yourself too hard! I think you'll find small changes to your eating habits and lifestyle will have a big effect on the way your body feels.
Look forward to seeing you here at 3FC and good luck!
