There are 2 theories of post workout nutrition. One says that you need to replenish your glycogen stores right away and another that says that carbs will stop any benefit from growth hormone stimulation.
Here's one source in the first camp.http://en.allexperts.com/q/Nutrition-Di ... orkout.htm
Here's one from the second camp.http://www.articlesbase.com/outdoor-spo ... 65152.html
I use to be in the first camp. I believed that spiking insulin levels post workout and reloading glycogen was the way to go. There is something to that.
However, after reading DiPasquale's thought on it (Anabolic Diet/Metabolic Diet), I decided to for go any post workout carbs.
I followed the no carb post wrokout program for close to a year. I haven't noticed any changes in my recover between the two.
As DiPasquale noted, in a 24-48 hour period you're body will restore glycogen back to the muscle cells, via gluconeogenesis. So, don't worry about it.
My feeling is that if your performing in an even in the morning and then later in the afternoon on the same day, you better off reloading carbs back in immediately after the event.
Gluoconeogeneis won't cut it for quickly restoration of muscle cells with glycogen.
As for getting a boost in HGH by not taking in any carbs. I question exactly how much HGH is released. In other words, Is enough released to make much of a difference?
My answer to that question is, I DON'T know.
It does make sense that abstaining from post workout carbs will allow you to continue to burn body fat much longer after your workout is over.
I feel (meaning I am guessing) that abstaining from carbs post workout was a contributing factor in my dropping from 202 lbs down to a svelt 184. :)
