This is getting a little bit easier, though I am knocking on wood. I find that it helps to have things to do to avoid downtime, where food fantasies can kick in. I had a giggle last night - I'm unabashedly a foodie, and in that context, giving up food altogether for a month is extra crazy.
I do find that I have trouble concentrating and focusing for long stretches of time. I wonder, though, whether that will ever change. I read an article (a published paper) somewhat recently which attempted to make the case that depression and obesity are actually ideal fitness for the performance required to sit and program for long stretches of time - the depression helps create a desire for isolation, the obesity (and the sugar binges which precede it) help create a constant high level of blood sugar, which (according to the paper) helps in concentration on abstract problem solving. Basically, it seems like "spending all day sitting and programming difficult things" can be intrinsically unhealthy.
I realize it's only day three, and I further realize that weight-loss is not the focus of this fast, but... my clothes fit me today. They're not tight. I'm not holding my breath and stomach in all day. Though I know this will probably go away when the fast is over, I do wonder... if healthiness in the body comes from loving your body (cue masturbation joke from Taisuke, Francisco, Joe...), then doing something which may be temporary but gives you a taste of feeling good and proud and happy with yourself can't be bad? I feel like this is a way of laying groundwork for actually preferring eating mostly vegetables, instead of truly craving chicago-style pizza every day. (Which, of course, I do).
