I love breakfast! No, I mean I love breakfast. I would eat eggs all day long if I could. I say these things to let everyone understand that what I am going to talk about next slowly kills me with every word because I absolutely love my breakfast.

We have all heard the old adage that "Breakfast is the most important meal of the day", now while this may be true in some cases as far as just kicking off the morning in a ritualistic manner and elevating your mood. We have also heard that breakfast is important for those of us who want to look good nekkid, because it kick starts the metabolism and reverse the catabolic state your body is in upon waking. But studies have begun to surface lately that are contradicting this once held truth.

I am beginning to see more and more evidence that proves to me that skipping breakfast may be a viable option to improving body composition. The first convincing piece of evidence that sold me on the idea is the hormones at work and their relative levels upon waking in the morning. One of the important hormones to consider is Cortisol, which is the hormone responsible for breaking down glycogen stores in the muscle and liver. Cortisol levels naturally elevate throughout the nigh and peak just upon waking. This had led most people to believe that because Cortisol levels are high and Cortisol is a catabolic hormone that are bodies are in a state of breakdown, but what the individuals failed to take into considerations is the relative amount of other supporting hormones at this period of time. Insulin is an importnat hormone that has to be in synergy with Cortisol to provide a proper breakdown of glycogen, but Cortisol is elevated in the morning and Insulin levels are relatively low meaning Cortisol does not perform in its normal capacity. Instead high levels of Cortisol in the morning triggers the breakdown triglycerides into free fatty acids for metabolization and lipolysis. Which means that waking and waiting to eating will kick start fat-burning, which is completely opposite of what most have believed for the past 5 to 10 years. Studies have also been published showing that Ghrelin, hormone responsible for hunger, levels raise throughout sleep and peak also upon waking. But what most don't know is that it also stimulates increased release of growth hormone and as growth hormone levels increase the amount of fat being used for fuel increases and the amount of protein being broken down decreases.

With all this evidence presented to me as to the hormonal interactions occurring upon awakening one can only come to the conclusion that prolonging your morning meal until cortisol and growth hormone levels return to normal may be a beneficial technique for losing fat. This conclusion I found out was also backed up by a study done by researchers looking at the difference between a group of participants that ate a big number of calories early in the day and a group of participants who skipped breakfast and ate majority of their calories later in the day. What the researchers saw was that the group that skipped breakfast lost more total weight and lost almost exclusively fat. While the other group did lose weight but lost it from a combined source of fat and muscle.

It may seem crazy, but what I am saying is that if you are someone who is struggling with body composition alteration you may want to consider changing your morning routine to allow you to put off breakfast until a few hours after waking. YEAH I SAID IT! TRY SKIPPING BREAKFAST. I have been experimenting with it myself and have seem some definite improvements as far as my own body composition goes.
