I finally updated my after pic and just wanted to share. I've lost a total of 45lbs and went from a size 12 to a size 4 comfortably. I'm 5'4 and before children I was a size 0 or a 2, but realize that I will never be that small again, so I'm happy with where I'm at. I have a very petite frame and have always been small, and I have always caught hell for looking "sick" or "anorexic", but that's just how I'm built. Now that I'm no longer having children, I figured I would do my best to get back into shape. So... Here I am.
EDIT - for those who are asking, it took 7 months for me to lose the weight. I stuck to 1000-1200 calories a day and did cardio (walking, treadmill, etc.) as well as sit-ups and squats every night.
