i would start at about 1500 calories a day, making sure that the food you eat is nutritious and healthy, and also spread it out throughout the day. having more small meals throughout the day keeps your metabolism going, instead of having 2 or 3 big meals - you never want to stuff yourself because that is when you start adding on the weight. see what happens...if you lose 1-2 pounds after one week with 1500 calories a day, you are on the right track. if you dont lose, drop it down to maybe 1300 or 1400, if you lose more than 3 pounds a week, then you are eating too little and you might end up losing muscle instead of fat, which is unhealthy...then you should up the calorie intake to maybe 1600 or 1700. everyone is different and has different calorie needs, you will just have to play around with it to see what is a good number for you. also remember to drink lots of water because it helps break down fat, and also when you are dehydrated your body actually retains water. good luck!!
