what I took from the author, and I'm in no way attempting to speak for him, but rather to restate what I think was said in attempt to test my own understanding:
it's silly to refrain from eating after an hgh shot because the hgh is going to be really doing its thing about 3-4 hours later. So no sense in taking a shot, then waiting an hour to eat, because you're getting a blood glucose response from the hgh shot, then you're getting a second response from the food an hour or so later. You're just prolonging the insulin response over your "fed" window.
So if your goal is fat loss, with the idea to get blood glucose low as fast as possible and as long as possible, then eat and take your hgh at the same time -- you'll get the blood glucose response from both the meal and the hgh and then you've got the next <however many> hours until you eat again to dispose of the glucose and start utilizing the free fatty acids that are still in circulation from the hgh shot a few hours earlier.
IOW...wake up, eat, take your shot, exercise 3-4 hours later. <repeat>
