Absolutely excellent advice from that blog. Being fat is no indicator of our value, spirit, intellect, or importance to others. Hinging our self worth or even our documented life HISTORY on how we think we look is to miss a lot of beauty. Worse, it robs the people we love of their memories, too, by forcing US (their loved one) out of the frame.
I lost the weight for a lot of good reasons and some mediocre ones. But I never hated myself and never stopped living because I was fat. I was a whole lot more than just that one attribute of my body!
