This ignores all research already done on the brain and nutrition, and also common sense. Its pretty well understood that the brain runs on glucose. Now of course if you eat too much or eat shitty food, you're going to have an insulin spike and sugar crash, and if you're eating too much you probably have other health problems that aren't helping. Healthy eating, good body weight, and regular exercise sharpens the brain. Edit: The number of people jumping on board with this "theory" in his blog comments makes me despair for the state of nutrition and health education. Learn you a physiology:

On Common Sense:
The human brain/body evolved to run on minimal glucose. Of the past 2million years of human evolution, only 10,000(from the agrarian revolution) of those years have we consumed excess carbohydrates in the forms of grains etc. Prior to that we were hunter gatherers and ate copious amounts of fat and meat with some vegetables (very low in carbohydrates) and every now and then fruits when they were in season.
We also didnt have the luxury of eating as soon as we woke up, we had to hunt for our food, so missing breakfast would have happened more times than not. Again our bodies adapted to that.
On All Research:
As mentioned in comments below our bodies run perfectly well in states of ketosis. With ketone-bodies providing a much more efficient longer energy burn than carbohydrates. (Think of carbohydrates as kindling and ketones as the logs). Many athletes (particularly the CrossFit athletes) run on ketogenic diets and get better performance. Here are some papers/articles etc. I dug up quickly, but there are many more.
