I think adding low fat dairy and high fibre fruit is the way to add the
extra calories that you need. I think that a snack of skim milk and an
apple or a bowl of fat free cottage cheese would be a good way to go.

If you are the kind of person that needs to keep up the spartan style
of eating that you have become used to then add olive oil or coconut
oil to your diet to hit your calorie goal.

Congrats on hitting your goal weight. I have a ways to go but I hope to
have a similar problem one day.

For the Maintenance phase of Atkins there's the book "Atkins for
Life".  A whole book about one of the four phases has the chance
to cover that phase better than a chapter.

As to gradually tapering off the fat, I do feel that the process
manages to do that somewhat. After Induction I feel that the Atkins
process fits one of the meanings of isocaloric - same calories.  Not
in the sense of 33/33/33 of calories of carb/fat/protein being equal,
but in the sense of calories being roughly equal week after week.
At you move up in carb counts the carbs that are added are the
ones that are more filling so there's a mathcing taper off in fat or
protein.

How far down the fat level goes, that would depend on the person.
When I've done the arithmatic it may be lower in fat than Induction
but it doesn't approach focusing on lean.  Let's take my approximate
numbers.  My ideal weight is 170-180 so my target calories is 1800.
My CCLL is 50 to lose; my CCLM to maintain is 100.  That's 400
calories from carb during maintenance, leaving 1400 calories.  My
protein minimum according to Protein Power is 77 grams but I tend
to hover a bit over 100.  That's 400 calories from protein in any
phase, leaving 1000 calories from fat.  At 9 calories per gram,
that's 110 grams of fat per day.  Some would call that high fat some
not, but no one is going to call that low fat.  It's also easier to
trade more protein for less fat and end up just in the two digists of
fat grams.
