I think you were a little harsh on Stephen.
Before I go on, be aware that I have read GC, BC/TDD in its UK hardback edition and the American paperback (including the update with the "Afterword" ) many times, read WWGF, listened to Gary's interviews and online lectures, read his blog, and corresponded with him somewhat.
I admire what he has done tremendously. Nevertheless, many questions came into my mind as I was reading it, and one of them was about the insulin response to protein. No matter how many times I re-read GC,BC I was still confused by this.
Yes, the insulin response to protein also causes a glucagon response, and this in turn causes glucose to be secreted from the liver into the bloodstream. So not only do we have an insulin response, we've got a glucose response. Are we to take it for granted that under no circumstances some of that might end up as fat in fat cells? However, I'm not so worried about fat storage at this point but what's going on with glucose control and insulin levels.
And we also know that under certain circumstances, glucose can be synthesised from the amino acids in protein. Some argue that this only happens under conditions of starvation, but that may only apply to people with normal metabolisms. Overweight and insulin resistant people by definitions have broken, or at least bent metabolisms, so how do we really know what might happen to some individuals in response to protein?
Let's look at another quote from that link you posted:
Quote:"For people without diabetes, the insulin and glucagon responses mitigate each other, and we’re looking at a healthy picture. For people with diabetes or impaired insulin response, however, this picture is much different. In diabetics, this crucial equilibrium is damaged. The body not only has difficulty compensating for blood sugar spikes from carb intake, it’s also at a disadvantage when it comes to low-carb, protein-based meals with the lack of insulin-glucagon balance. (Another reason to avoid developing diabetes from the outset.) Nonetheless, diabetics fare better with a low-carb diet."
So basically it's no problem for people with perfectly healthy metabolisms.
But that doesn't describe people who are significantly overweight does it?
As to high-protein diets never causing weight-gain, I'd say be careful when you say never. You only need one black swan to prove that not all swans are white.
By the way, like you, I'm a Brit, and know what you are on about with the BNP, etc.
Back in the 1980s, I was marching against Cruise missiles, and my wife was linking hands around Greenham Common.
Nowadays I leave that kind of stuff to you young hotheads :-)
