Txang72,Fat is the about the only way to keep your calories up on Atkins!

Look through the Best of forum or do some searches and you will find a lot of information there.
I believe one link is ..Confused and scared to eat Fat,

There is so much information here that members have researched for us for the last few years, you just need to do a little searching. When I have some more time I will come back and paste a few threads in for you!
Good Luck!
