It's actually very easy!! Almost too easy. There are many ways to get that fat! Olive oil, salad dressings, heavy cream and my favorite of all, cheese!!!!
I put up my fitday menu for a couple of people already. Here it is:

Don't click on the link. You have to copy and paste it into the address bar. Yahoo wont let me hot link it.
I am only 139 and I am a female so it wont be like yours, but you should be able to get the picture.
Fitday is invaluable. Start off by picking your favorite high fat foods and get as close to MR.X's #'s as possible. When I started I thought the same thing, but now I find that I can easily add up the fat.
Some people will advise peanut butter and nuts. I did that for my first week and it definetly slowed my progress, so I cut it out for week 2 and 3. Now I am seeing a big difference. Not in weight but in BF.
Also, try to stay away from protein shakes. If you have too much protein you body will start using that for energy instead of the fat. I only have one once a week. That's on day 3 when your protein intake is almost the same as your fat intake.
Oh and if you are not lower than 15% BF then you may want to skip your carb up day the first week or two.
And one more thing; the first week is really HARD. You may experience lethargy, depression, irritability...after the first week it's cake, so stay strong.
If you have any questions, please don't hesitate to contact me. There are a few of us doing it on the board and everyone else is pretty helpful as well.
Good luck!!! Have fun playing with those numbers!!
