Is multigrain bread more filling than white bread?!

yes more fiber therefore more filling

Sam,

It will depend on the bread... and the eater! With modern food processing techniques, even multi-grain breads can be very light and fluffy. But sometimes even very dense breads filled with seeds and nuts can fail to satisfy. It depends in part on the eaters expectations.

Thanks for asking this question. I'll be very interested in what people have to say about it.
For me, it depends on the bread.

Multi grain not only fills youup better but keep you fuller longer than white bread.

YES. Read the chart on the packages and compare then it becomes obvious.
