No, it IS true, but what he doesn't tell you is the 40-80IU's of insulin they use to make up for it. I'd much rather take more gear than that much insulin!
Do you know a lot about insulin?
How does insulin's effect on its receptor effect oxidation of fatty acids? I've always been curious about that.
I'm guessing that because you know so much about it, you'll be able to tell me that.
Does insulin have a pronounced effect on glycogenesis? If it does, why is this important?
Actually, you're so lean right now it may not be safe for you to use the precious amount of glucose it would take to explain the intricate details of the physiology of insulin to me.
Just focus on your show for now.
When the show is done, and the ability of your neural synapses to conduct proper chemical messages is restored, you can inform us all about the true effects of insulin.
