What is the Healthy Amount of Weight to Lose Per Week?

Right now I'm trying to do a 500 calorie deficit per day so that I lose about a pound per week. I was thinking of doing a 750 calorie deficit, which would be 1.5 lbs, but I don't know if anything over a pound per week would be healthy. What would Daniel and Kelli consider to be a healthy weight loss goal per week?
