Anne, I think you could try eating up to that range, as long as you are exercising. What I've found is that what I eat is as important as how much. If I'm eating whole grains, plenty of protein at each meal or snack and very little to no sugar, I drop weight easier than if my diet is including sugary things or any white flour through out the day. Everyone's body is different, sometimes you just have to experiment with what works for you. For some people, eating on the high end of their calories one or two days a week is okay, but not every day.
