angie!
hey there, welcome to 3FC! Kudos to you for making a change in your life, you're on your way to a healthy new you!
first off, 1200 cals? no no no, thats way too little for u, esp if ur exercising...heres a link, one of the other ladies on this site posted...its easy to follow and gives you how many cals you should eat based on your weight, height, activity level...but in my opinion they are a bit too high, and until you see your trainer you should stick to the stationary life style caloric intake values even though your exercising...heres the link...

another thing, keep doing what your doing exercise wise, you dont want any drastic changes before meeting with your trainer...you dont want to go in there with sore muscles or an injury bc you're trying to impress your trainer...
so, eat lots of fruits, veggies, lean meats, low fat dairy, and healthy carbs, stick to your exercise regimn, and good luck to you with your trainer!
