I always liked the book Fat is a Feminist Issue and I find the notion that women are expected not to take up space in the world or be big enough to take care of themselves to be a compelling reason to try not to (I still do) worry about whether I am too large or too small. Women (I know men have weight. body issues too but they are not as targeted as women) get to eat and be healthy and be strong enough and big enough to take care of themselves. It is sort of like the clothing and shoes for women (dainty, fragile, not good for running or walking etc but instead constricting and deforming etc). I don't know, this kind of winds me up.
