It's not about controlling insulin it's about controlling calories. Protein, by itself, causes insulin release. More than carbs, by themself. However, try to eat 1,000 calories of chicken breast in one setting. I dare ya! 1,000 calories of pasta is much easier. 1,000 of calories of pizza is easier still. Control calories and you control insulin.
Granted, this is a vast over simplification, because many other factors play into it. Protein and fat are more satiating is the primary factor. Insulin resistant people will have the output side of the energy equation affected by carb heavy meals is another big one.
Correct me if I am wrong, because my understanding is purely based on my own health rather than being interested in low-carb debates.
From what I understand, eating food will create an insulin response (yes, we agree). It will take carbohydrates and since glucose is a component (usually of that carb) the insulin will effectively "tell" the cells to take it and make into glycogen and store it somewhere. People who are insulin resistant can't properly secrete enough or secrete too much insulin so the storage isn't working perfectly. Glucose remains in the blood, which then causes problems -- to cells themselves, arteries, organs, and so on. This elevation of the glucose in the blood is what eventually causes/creates/is defined to be diabetes (if the blood sugar levels don't drop to normal levels).
Food -- in general -- causes this response. Carbohydrates more than protein or fats, because proteins and fats are broken down differently because of the different levels of glucose that they contain. I agree that protein increases blood sugar levels, because I've read on this very board about people who are struggling to manage their BGL who are just eating beef or chicken and not improving their numbers.
I do agree that calories matter, but I think that the quality of the carbohydrates matters as well, especially if you're dealing with possible problems with your insulin response.
I didn't know I had issues with IR and assumed I was normal, except I could easily pack 3000 calories in one day between fats/proteins/carbs and still be hungry at the end of the night. It all stemmed from my blood sugar crashing and being overly elevated when I ate, and so on until I reached 200 lbs and a doctor finally told me what was going on in my body.
Maybe as nutritional science and more studies on diabetes, metabolic syndrome and insulin resistance are done (and I know they are being conducted even as we speak) this will be clearer. And maybe insulin alone is not the only one responsible for what happens -- in fact, I'm sure it's not the only hormone that is involved in all of this. But it does have an effect and I think it also affects the other signals we get for satiety and fullness.
*sigh*
All I really know is that Paleo style of eating works for me. When I eat refined carbohydrates and grains, I gain weight and I can't lose the weight I've gained. I'm learning that lesson again right now. The 7 lbs I gained from December are 100% based on my denial/belief that I am "normal" and I can eat like "normal" people.
