Doubt this too...as an increasingly sedentary population we have little need to fuel up for our mornings. Our daily routines are nothing like they were when many of our breakfast traditions were formed. As late as 1930 around 30% of U.S. workers were farmers, eating big breakfasts and doing hard physical labor, another 30% or so worked in manufacturing and construction. Today the average worker sits most of the time, doesn't walk to work or anywhere else.

When you take on a load of calories and then don't immediately begin a physical task to utilize those calories the body has to store them, ramping up insulin and often overshooting causing a hunger spike, that notorious doughnut break at 10:30...cue another insulin spike and it's no mystery why insulin tolerance and chronic metabolic syndrome/type 2 diabetes are so prevalent.
