I am trying to lose weight I watch what I eat and drink. I stay away from fast food I work out but it doesn't seem to be working out I am not losing?

Cut out carbs. You may be eating too many carbohydrates. You only need about 150 grams per day. When you eat more than you need for fuel it goes to fat stores. Don't count fat or protein calories, just carbs.
Not enough time. The most common cause is that people give up too quickly because they become discouraged. Base success on the number of months using the diet rather than pounds lost.
