I love it when people have the good sense to divorce getting healthy from meeting a certain beauty standard, and still more when they point out why that standard is unreasonable. Great story about J. K. Rowling too.
If you need encouragement to lose weight for health, not some artificial standard of beauty, this might be the blog for you.
ETA: J. K. Rowling's take on weight in her own words. Great story!
