I think that life's too short to get worked up about others having differing opinions. I think someone railing against "unsupported opinions" of others doesn't have a leg to stand on when offering his contrary unsupported opinions. And I think there's always going to be this back and forth, and so I'd better do what I have been doing, which is making up my own mind.

I have type 1 diabetes and can most defiantly confirm that high intakes of protein will require a does of insulin at almost a rate of about 35% of what carbs normally require! But if you are eating only 30grams of protein per meal then this is going to be a negligible amount of insulin and protein will NOT cause spikes in blood sugar that require a-lot of insulin (causing a "blood sugar roller-coaster") if eaten alone, which is actually what I think the authors of these "low carb" book were getting at.
Also agree with the fact that exercise is important as I can eat as low carb as I like and I will require less insulin if I am eating low carb, but my ratios of the amount on insulin to carbs (eg, 1 unit of insulin to 10grams of carbs) will not change unless I exercise. So basically what I am saying here is that exercise will make a person much more sensitive to insulin- hence, they will use less and less insulin does actually mean you will store less fat as insulin is a fat storage hormone (it allows the sugar in your blood to be changed into energy your body can use/store as fat). Obviously, in order for you not to have much sugar in you blood that can be turned to fat you need to be eating less over-all and as high carb sugary food is easy to over eat, it should probably be restricted/not eaten if someone wants to lose weight. BUT insulin is only responsible for the conversion of about 40% of sugar to energy in the body. Your brain and exercising muscles can actually convert sugar to enery via different methods. Also fat is converted via a different method.
So what the man is saying is true. But he is also twisting what others say about a low carb diet. I mean who doesn't realize that for good health you are probably going to need to combine exercise with a healthy diet... and yes in a way sugar does cause type 2 diabetes, but only if combined with the right genetic and lifestyle factors...
I mean it's kinda obvious to any person that an athlete who eats 300grams of carbohydrate a day in the form of potatoes and rice is probably not going to develop type 2 diabetes and that a fat, sedentary person who consumes 300g of carbs in the form of sugar/donuts/cereal has a much higher chance of developing type 2...
