You can always do a little trial and error. If 1500 seems to low - try 1600 or 1700. Also, watch the quality of you are eating - meaning, 100 calories of crackers is a lot different than 100 calories of broccolli.
I am finding that it doesn't have to be all or nothing - if 1500 is too low, I can try 1800. It doesn't have to be 1500 or foget it and go off plan. If one day, I need an extra snack, that is ok. If I have a "bad" meal, then I just need to be more dilligent about my veggies the next day.
If you are hungry in the evenings - try planning a larger dinner (with more veggies!) or try planning for a healthful snack in the evenings.
