Insulin promotes MANY anabolic activities, including lipogenesis (as you mention), as well as acting as gatekeeper for the entry of glucose, amino acids, fatty acids, etc, into cells. And ALL of these activities are necessary steps in the process of gaining fat. So you’re right, it’s probably misleading of me to focus inordinately on any one of insulin’s actions as being the insulin-dependent activity I’m trying to avoid by eating in the manner I do.
That said, and until/unless someone can show me research to the contrary, I still maintain that the concomitant increase in glucagon induced by a high-protein meal does little to offset the potential fat-storing activities of the insulin that is also released. In fact, by promoting gluconeogenesis in the liver, glucagon acts as an ‘unindicted co-conspirator’ in the process of turning excess dietary protein into fat.
Any way you slice it (if you’ll pardon the expression), too much protein intake will lead to fat gain. Now, can people get lean eating in the manner you suggest; ie, gnoshing on protein all day (with the caveat that they must run a caloric deficit)? Absolutely–many BBers have gotten freaky lean doing so. Calories in/calories out trumps all.
In a nutshell, all I’m trying to do is eke out an extra percent or two of fat-burning. By avoiding carbs and protein in the early part of the day, I can keep insulin levels near baseline, which (the thinking goes) will have the effect of prolonging the fasting state that developed overnight.
