So I recently read this article:
http://www.leangains.com/2012/06/why-does-breakfast-make-me-hungry.html
Tl;dr, the author posits that hunger pangs post breakfast are a serious issue for low bodyfat people, and that eating breakfast at the peak of your cortisol levels (30-45 minutes post waking) leads to significant hunger pangs. For the average joe (meaning the truly average, overweight, out of shape etc person), breakfast can be a good thing because at their body fat levels, the "cortisol awakening response" pushes their insulin sensitivity higher in the mornings (to levels of ~20 nmol, as opposed to 2-5 nmol later in the day and evening).
Although the feeding-induced insulin peak comes much faster and is much higher, due to the meal coinciding with the circadian cortisol peak, the net effect should be that average insulin secretion and blood glucose in the post-prandial period post-breakfast is lower than later in the day, under a low-cortisol fed condition. In a way, Average Joe’s sluggish pancreas might actually benefit from the augmented insulin response in the morning.
Eating (higher glycemic index things more than low GI things obviously, which is what many of us do eat with breakfast, including milk, toast etc) during this period causes you to have a more pronounced effect to the extent of hypoglycemia, which causes significant hunger pangs. These become more pronounced when you're leaner.
I do notice the effect as being real, and as it stands, Ive been having most of my nutrition in/around/after the time of my workout. Anyone care to share any thoughts on the authors analysis, or personal experiences?
