An interesting study on the macronutrients of your day's first meal setting the type of fuel you'll burn the rest of the day.  Link is here: Bacon+Eggs For Breakfast

...research team found that fat intake at the time of waking seems to turn on fat metabolism very efficiently and also turns on the animal's ability to respond to different types of food later in the day. When the animals were fed carbohydrates upon waking, carbohydrate metabolism was turned on and seemed to stay on even when the animal was eating different kinds of food later in the day.

"The first meal you have appears to program your metabolism for the rest of the day," said study senior author Martin Young, Ph.D., associate professor of medicine in the UAB Division of Cardiovascular Disease. "This study suggests that if you ate a carbohydrate-rich breakfast it would promote carbohydrate utilization throughout the rest of the day, whereas, if you have a fat-rich breakfast, you have metabolic plasticity to transfer your energy utilization between carbohydrate and fat."

I don't avoid carbs, but I do avoid breakfast carbs (and a max of 50g / day).  You will feel the difference if you try, and you'll not be 'dying for lunch'.  Experiment with yourself, we're all an experiment-of-one.
