tlynne - many people continue to lose during P2/3. The idea is to introduce more "real" food and wake up your pancreas. I think you should phase off the way it is set up (my opinion).
Depending on your height and activity level, 1000 calories a day may be way too low for you to be able to get adequate nutrition once you phase off. You might try talking to a nutritionist and try to set up a plan you can follow.
