Keep in mind this is just a guess but maybe your body is programmed to think it needs a certain level of body fat which you have dropped below and its trying to compensate by telling you it needs to eat to get back to that level. If you have been losing steadily you might want to go to a maintenance level of eating for a week and let your body get used to its new weight.
Probably not what you want to hear since you are pretty close to your goal weight.
The only way of finding the limits of the possible is by going beyond them into the impossible. -- Arthur C. Clarke
