(as an aside - $15 on fast food a day! for your sake I hope it's relatively healthy stuff!)
I try to stick to just the burgers, not soda or fries often. The jalapeno bacon fries at Wendy's have been an exception though.
I feel like it's not really that unhealthy considering fat's actually not bad for you and dietary cholesterol doesn't become blood cholesterol, which was surprisingly still good for me despite this diet last it was tested. Results vary depending on the genetic lottery.

I'm thinking a generic McDonalds burger here with a wilted piece of lettuce, a slice of tomato and some gherkins. You could probably construct a healthy veg burger, I have no idea where you'd buy one. Something like subway seems like a better bet.
This [1] suggests vitamin C would be the big problem for a Big Mac (1% RDA) followed by vitamin A (4% RDA). 100 burgers a day sounds quite hard to stomach, so the question becomes how bad the western diet is.

I'd recommend you go and buy some real food. Regardless of macros, McDonalds is full of garbage, especially in the US.
