I found the recent article "Fat City" to be very informative and gripping, and thought that as a reverse thinspo, or as something therapudic for those of us who have suffered from binge eating/being overweight in the past, to post what it actually takes to be fat (so we know that these fatties talking about 'metabolism' are full of shit). Here's an article to get it started. It's gross, so just warning you (or egging you on if you want to be turned off of food)
