Figured I would post this here instead of an IM for everyone to see. When does the body begin to produce cortisol...is it during the workout or after when the body rests?

Cortisol is a hormone your body produces in response to stress. As the stress is increased, such as the stress you put your body through with a hard workout, this is what happens. As more and more glycogen and glucose is burned up for energy, blood glucose levels begin to drop-off, which in turn cause insulin levels to drop drastically.
These drops give rise to the catabolic hormone Cortisol. So, the harder you train, the more is released. Cortisol is the last thing you want to let go post-workout. Cortisol is the chief hormone responsible for “burning” muscle up for energy. Cortisol literally converts muscle tissue to proteins for conversion into glucose. This is your body’s way of producing energy when all readily available energy (glucose) and stored forms (glycogen) of energy have been expended. To make up for this fall off of energy(depletion) your body will go into a process called gluconeogenesis to produce glucose from amino acids in the liver. The result is disastrous to us. Hard earned muscle is broken down and used as energy, and diminishing any potential gains, not counting what you could lose during your workout.

yeah I know that, but can you start your insuline spike 'during' your workout. These are questions I'm getting at my gym and I need a snappy comeback.

If you are dieting for a contest, and calories are tight, the last thing you want is muscle breakdown of any kind, as you are not taking in enough nutrients of to build muscle at this time. Preservation of mass is essential while trying to sway your body toward fat burning. In this case, it may be wise to supplement beforehand and during your workout with amino acids and glutamine, thus preventing cortisol(breakdown). You cannot afford breakdown of tissue because you cannot rebuild it. But if calories are at a premium, meaning you are trying to gain, it would be much more anabolic to have your post workout shake, the effectiveness of it would be much greater. You are rushing nutrients to start the rebuilding process immediately. One other note, in some folks, "eating" during training takes needed blood flow away from the muscles as it is needed for digestive purposes, so vital energy is consumed. So, in conclusion, if dieting, limit cortisol as much as possible with supplementation, BCAA's and glutamine are good, you can sip on a small mixture of simple carbs and protien(but after has been proven to be best), but if not dieting, then the post insulin spike is the most anabolic thing you can do.
