This 2007 interview with Linda Bacon, author of Health at Every Size
From New York Times writer Gina Kolata, a discussion of various types of medical studies and how to read them (skeptically). The accompanying graphic is cool too.
From Noël Figart, The Unfit Person’s Guide to Fitness. I found this to be a useful starting place when I began exercising after a few years of not exercising. Lots of fitness resources assume you can already do a pushup or run a few miles. This one doesn’t.
Living ~400lbs 
That fitness guide would be awesome if the author didn’t repeatedly equate “fat” with “unfit” and vice versa. It was quite confusing to be told that because I am out of shape, my muscles are supposedly working much harder than other people’s. I re-read that sentence five times until I finally moved on to the next and figured out that “out of shape” meant fat in this case. Argh!
Well, I don’t intend unfit as a synonym for fat. Perhaps I should reword.
I mean, I can swim a mile, I’m 5’2″ and weigh over 200 lbs. I’m certainly fitter than most.
