Hello from Cape Cod, MA!!

Hi, my names Sara and I am new to MFP. I am 5'4 and weigh 177lbs (yikes!) I have always weighed 110 until I had my daughter a year and a half ago. I am trying to go back down to around 120 so I have to lose 57lbs! I'm new at this whole eating healthy and weight loss stuff and don't have anyone to really keep me motivated so that's why I joined this site. I just started a diet on Monday of this week and I try to eat around 1200 calories a day, per my dr's orders. Any tips, tricks, pointers would be greatly appreciated!! Look forward to talking to some of you! =o)
