Cheryl, I usually hear to cut out 500 calories per day, but I think it's different for each person. If you sign up for an online program like My Fitness Pal or Fitday, it will tell you how many calories you should aim for based on your height, weight and age. When you first start out, you will lose quickly, then it will slow down, hopefully to a steady pace. Some people get anxious to see a loss and cut back too far. That's not a good idea, because if you aren't eating enough you will get hungry and end up binging. Eat foods that give you the best bang for your buck. Slow and steady wins the race.
Good luck to you.
