I kinda sorta did it that way too, but not intentionally. I stopped drinking soft drinks, then later thought "What else can I change?" Cut out fast foods. Cut out salt and processed foods first, at my doc's suggestion - either that or go on blood pressure meds. That got the ball rolling for more changes. More organic foods, more fresh stuff, smaller meals, etc.
I keep promising myself a pint of Hagen-Daas a month, but it's been longer than that now. I'm afraid I'll go crazy if I break this stretch without it. It's been almost a month since I've eaten meat, too, but I'll soon take care of that, I promise you, and whatever it is, it's gonna have bacon and cheese on it.
