Actually, I am not sure about the statement regarding the bread. I grew up with bread, every day I went to the local bakery and bought 2 or 3 baguettes. Every time I came back home about 2/3 of one was missing, already in my belly. The stuff is so tasty, the smell so spell-binding when it is still a little bit warm from the baker's oven that you simply cannot help, hungry or not. 30mn later, with almost a whole baguette in my belly, I became ravenous and had to eat half of another baguette at least, but this time with more foods, whether they were french fries, pasta, what-not, bread was there too. When I was old enough to drive a car, I would then drive to the bakery ... but ate even more bread!!
So what was driving my behavior ? something in the bread maybe ? Today, I don't eat bread and I am not ravenous all day long. I eat carbs all right (potatoes, rice, even pseudo-grains sometimes, plenty of fruits in season) yet I am not ravenous. It is the nutrient density I believe, and the very small amount of anti-nutrients. That is what drives your eating behavior: the body's hunger for the needed nutrients and bread offers nothing but a fake impression of nutrition
