In the beginning, you should be able to lose with higher fat .... especially if you have a lot to lose. Go with that as long as it continues to work for you.
Later, you may get to the point where you might need to lower your fat intake (temporarily) in order to get off that final 15. But I wouldn't worry about crossing that bridge until you come to it.
What my food was like in the beginning and what it is like now are two very different things.
