Renea, it really is a tough question! The thing is, each body works so differently! I do best on one fruit and one starch a day, but often eat a lot of carb-heavy beans and don't see any side effects from that. My carbs are usuallly the lowest percentage of my calories, but even on days when it's the highest, I don't see a marked difference in my weight loss or cravings.
I'd try to focus more on what you're eating than how much, per se. Obviously, calories count...and fitday helps you keep those in check. But, IMHO, don't stress too
hard about the percentages of carbs, fat, and protein...okay?
