Last month I said white flour at breakfast made me hungry all day. Well... that's not exactly the case...
As long as I eat a good bit of protein and not a lot of white flour, I do fine. For example, this morning I ate about 3 oz of turkey sausage and 1 slice of white bread toast. And I wasn't hungry till lunch! That's been the pattern.
I'm pretty happy about that :) It means I can eat a slice of toast or a biscuit without compromising the rest of the day's food.
