I reread part 1, and it talks about set point theory.
From personal experience, this may be valid, but keep in mind, all this advice is given as a possibitiy, not a certainty. Your body may react this way, and want to gain some weight back to a higer "set point" or it may not.
The advice is good, find out what your recommended intake is for maintaining your current weight, if you are where you want to be. Don't increase your calories all at once, just adding a few hundred a week and see where you are at the end of the week will allow you to ease into your new plan.
The recommendation to continue or even increase activity is also valid, you may have noticed during the losing phase that your activity level and or intensity level of your workouts had to increase to continue to lose at the same rate. Our bodies seem to need to switch up activities to get the same benefits over time. You can just rotate cardio activities if you like, bike for a few weeks, run after that, back to the bike, or try a cardio class.
