I do only hit Mickey's on a rare occasion and usually for breakfast. Not because of diabetes but more the 800 fat grams per bite. But, in college, I used live off two things. There was a time there (After a year of CDC pizzas....goot gawt) that I'd alternate every night between a quarter pounder with cheese, large fries and a coke....and Wendy's double with cheese (Mayo, ketchup and mustard) large fries and a coke.
When you're a 20 year old college kid lifting weights and playing every sport under the sun and throwing the Frisbee, running the stairs at Beard Eaves and chasing pus....I mean the dog.....you don't really think about the fat content. But then, when I was 20, nobody knew to worry about it.
