Those meals are not on the atkins fat fast list. But if you keep the fat to calorie and carb ratio, I suppose you could modify it. For fast food, somethign deep fried, or a greesy cheese burger w/ bacon is all I can think of. But fast food is bad and I dont think you eat it on the fat fast, its only for a few days! Dont do the fat fast if you want pancakes and fast food, if you are going to do it, do it right!

there is the link for the atkins fat fast. There are no easy paths to losing weight, you get out of this diet what you put into it. Its just for a few days, I think you can give up those foods that you shouldnt be eating anyways. Best of luck to you.
