Starting a Diet

So, I've decided to join my friend and start a diet. She's been counting calories for a month and a week, and lost 12 lbs. We are about the same height and she allows herself 1200 calories a day. I did some research on webMD and to loose 2 lbs. a week, I should only consume 1200 calories a day. I am adding a workout each morning to my diet and hope I get to my goal a little faster. Well, hopefully this works!
