What all this pushing does to some of us is simply create the will to resist. They’d have to get my jaws open with a crowbar now to get dessert down me. These are the things I long to say (but haven’t yet) when badgered by the dum-dums: ‘No, I do not have a wasting disease. Yes, I love good food. Yes, my taste buds are normal as yours. Yes, I could get through that plate of spaghetti carbonara like the garbage scow working Madison Avenue if I took a notion. No, I am not out of my mind or even particularly neurotic (about food anyway). Staying slender is a deliberate act of will and I do it not so much for health reasons but because five extra pounds or three or two go straight to my stomach and it becomes distended as though a whole watermelon were in there. I have always had a stomach problem, and heavy exercising–I do an hour a day–does no good whatever unless I also keep the weight down. My mother was pear-shaped. I am potentially pear-shaped. Two reputable, conservative doctors have both recommended I stay at this small weight. It takes a great act of willpower to eat little enough to keep my stomach flat and my hips from expanding, despite all the exercising, so please get your beady eyes off my clam broth and go jump into your own potage Saint-Germain with cheese croutons, you creep!’ Everybody thinks skinnies have some special metabolism (and some perverse skinnies encourage them to think that). This idea is reassuring to fatties because how could anybody expect them to stay slim without that old special trick metabolism. Sadly there is no trick metabolism–just self-discipline, which is maybe the neatest trick of all.
