Simply can't do one meal a day. But I don't think of food in units particularly. As for snacks...one little piece of 70% bittersweet chocolate has 50 calories and that works for me.
Not eating for most of the day was difficult at first, but it became fairly easy after about two weeks, and it's the only form of dieting I can pull off (I find life rough enough without treating food as units and penalties). I'll sometimes pop a dextrose tablet, or grab a slice of Wasa.
I'm a bit leary about the daily weighing thing. Bizarrely, my own weight hasn't budged in months, although there's no question that the spare tire I had in the spring is now gone, and my abs are all visible, and very 'displayable' again.
As for the daily weighing thing...I resisted doing it for about 50 years now. Ed weighs himself every day. And then adjusts his food slightly by the results. He never talks about it. I am not aware of his actions really. It is his 'way' and for him it works. This is basically my last hurrah and if it will help this time, well, I'll do it.
Congrats on your displayable abs. It's too late for me I fear. Enjoy it!
