The pressure to be thin, which causes guilt and obsessiveness around food, is terrible and starts so early. For me, it started at sixteen when I left home and gained weight for the first time and was told by a slightly older boy, out of the blue, that I was "too plump." The shock of that lasted a good long time.

As an adult I generally feel this pressure to be thin, not from men, but from other women. As a silent or not-so-silent competition, a constant monitoring of who's thinner, comments about it - either compliments or veiled insults doesn't matter - it always drives me nuts.

Sometimes I think of blogging as finger exercises for a violinist; sometimes I think of it as mulching a garden. It is incredibly useful and helpful to my "real" writing.

When you're sixteen and struggling to forge an identity out of a morass of hormones and daydreams, remarks like that cut a deep groove in the brain. I trace the ongoing, victorious-feeling semi-starvation of my twenties directly back to adolescence - as a way of showing those assholes that I could control my appetites... Which is so sad, in retrospect, because of course no one cared.

I was also writing in a tradition and trying to do something different with it, something that hadn't necessarily been done before, which was a risk, but it made it interesting. My relationship with food has been complicated and rocky and not always wonderful, and it's a lens through which my entire life and identity are refracted.

Blogging is different from both journal-writing and writing for print. It's more fun than either of those. The freedom to write whatever I want and the unmediated connection with readers are the payoff.

Starting the blog was a way for me to generate this nonfiction first-person voice naturally, gradually, without feeling performance anxiety. It felt a bit like keeping journals when I was younger, but connecting to an instant readership without having to wait for publication made it also immediately satisfying.
