I JUST read something about this today and decided to try it. I got a printout from a website where I put in my weight, height, age, etc. and it gave me a calorie total for Mon-Sun. For example, today was 1349, tomorrow is only 1068, but Wednesday is 1695. So it zig zags back and forth (I think I found it by Googling "zig zag calories"). I really don't want to hit the dreaded plateau so I thought I would give it a try. I think it will be great on days I know I'm going to eat out or go to an event or something.
