I remember the whole pink slime thing grossed me out when I first heard about it. And it's true , when you get away from junk food , and other things like baloney and cheeseburgers and fast food , you'll feel like crap if you eat it again. Back in college when I was lifting all the time , I spent about three months eating perfectly clean .
I had one cheeseburger at the end of all that, and I thought I was going to throw up . I was sick the whole day . I also have had family members and friends eat clean for several weeks, and the first time they ate a hot dog or frozen pizza they became severely nauseous .
And it's true that if you do go without certain foods and drinks for an extended period of time , you won't miss them. I haven't had Kool-Aid or cake or pop tarts in probably seven or eight years. Once you get through those first few months without something, you're out for good if you want to be. I once went three years without a hotdog , but I screwed up and had some for July 4th. They made me feel like crap and I had to cut them out all over again. It's been well worth it though.
I've got an advantage though, in the fact that my family never really did eat fast food when I was a kid and we still don't. So I really don't have any desire for it.
