If I eat 3000 kcal from foods that are high in protein, high in fat, or high in fiber, and I burn 2000 kcal, what's going on with the excess calories? How works automatic weight loss?

How the very low insulin levels will limit total caloric intake? And what's very low insulin level? In principle, the insuline level is adequate to the kind of eaten food and to its absorption speed/time. Please, explain what you mean.

Again I can't understand the main principle.

1. You confused me on the first one. I just call it "automatic" since the foods help regulate most people's appetite. That is protein, fat, and fiber are more satiating than high-glycemic carbs. Typically, most people don't eat more calories than they burn on the diet, although mqgeek is apparently an exception. By that I mean that only if they're not consciously trying to eat more. The rules may change somewhat for an athlete, etc. But when changing to this diet from the typical American diet, it tends to regulate total calorie intake (by regulating appetite) without the need for people to count calories.
2. Low insulin doesn't lower calorie intake. (In fact, some would argue that it has an opposite effect.) However, even relatively low levels of insulin inhibit your body's ability to burn fat. We keep insulin levels low, we keep the rate of fat oxidation high. Low-carb diets, and especially, very-low carb diets keep insulin levels very low. I can try to quantify it somewhat using information from Jeff Volek. Keep in mind, I'm no expert on this, but if numbers mean anything to you, I'll throw them out there (someone who knows a lot about this could ask me a lot of questions that I wouldn't know how to answer, so remember, this is just reference material from me, not by me):
*Moderate increases in insulin after an overnight fast can decrease fatty acid levels from 500 micromoles/L to less than 10 micromoles/L. So this demonstrates how powerful insulin is.
*On the flipside, inhibition of insulin secretion can allow fatty acid levels to increase to more than 1000 micromoles/L.
*Also, when insulin levels drop below 25 micro Units per ml, you see a marked increase in free-fatty acid turnover. It literally "spikes".
So the bottomline is that if you can keep your insulin levels as low as possible, you'll signficantly increase the rate of fat oxidation. Obviously, you can still lose weight withoug doing this, but doing it helps to maximize and speed fat loss.
3. The main principle is regulating total calorie intake without counting calories, while at the same time "maximizing" fat loss. Of course, the diet shown here doesn't completely maximize fat loss--that would require ketosis!! [img]smile.gif[/img]
Also, between you and me, we only recommend "lean" meat b/c it's politically correct here in the US
