IIFYM was never intended to be a diet. It originated as just something that was said when people asked on the bodybuilding forum about if they could eat a certain type of food such as a mars bar etc. The response mainly being, yeah if it fits your macros.......bro. Shortened and bam.
It is meant to be used to get foods in that are normally classed as "cheat" or "bad". It isn't meant to be used for 90% of your cals. That is where people fuck it up fierce. You hardly see someone who looks decent that follows it with that attitude.
[MENTION=7082]jzpowahz[/MENTION] ; can most likely comment on this as well. He posts a large amount of his foods that look great but I would assume the stock standard stuff he doesn't post is a large amount of his diet as well.
And lastly, wtf is wrong with some of you kunce, try not to fuck up one thread with that shit for once
