About seven years ago, I resolved to ignore any desire and to forgo any offer of fast food to the extreme of even refusing to enter a McDonald's to use its restroom. For the first few years, I was successful, but later on, I was more relaxed on this personal dietary policy. I started to participate in base fast food affairs again, but to a point. Then a few years ago, I returned to my fling with Dunkin' Donuts. It doesn't help that I've only recently taken coffee somewhat seriously. Still, I don't routinely drink coffee as a casual beverage or for its bitter, over-sweetened flavor; I only drink it when I need it (on the order of once a week), which is different than my approach to alcohol. With alcohol, it's completely reverse. I do not drink beer or wine, etc., for their utilitarian effect, but for flavor and taste (mainly because light-weights like me can't hold alcohol well, but then again, I am stereotypically not expected to).
I am now turning to devoid myself of soda (I had unsuccessfuly tried this before), potato products, and junk food (namely sugar conglomerates like soda, chocolate, and cookies). I was going to declare it a vegetable-and-water diet, but it wouldn't be correctly named. I don't know what kind of name it deserves besides simply "eating well," but I do know that I'll get right on it as soon as possible ... just after I finish these last two Entenmann's donuts for breakfast.
(I've been consistently drinking about 2.4 L of water a day.)
