The promotion of anabolism is more a function of protein sparing than a direct stimulus. Using Nitor on a hypo-caloric diet you spare protein for energy via an increase in fat oxidation and lipolysis.
Gotcha. This is true of other effective thermos - for example, good old EC does this also. By promoting insulin resistance, fat oxidation and lipolysis are enhanced since that's what insulin resistance does in a deficit, shifting substrate oxidation away from carbohydrate use during exercise - a very strong positive when you're trying to burn the fat off your ass!
In a surplus of course, this is a negative. That's why such thermos are generally counterproductive during a bulk. In this situation, insulin resistance prompts our cells to downregulate receptor activity in an effort to protect themselves against the toxicity of elevated insulin.
First to be affected with insulin resistance in this situation is the liver, then muscle and finally fat cells. In a surplus, this means means partitioning toward fat cells will be enhanced while liver and muscle uptake are both compromised. (Heh - that's right, it makes you turn into a GURL. <cries>)
So interesting that - at least where insulin resistance is concerned -precisely what you
want for a cut is precisely what you
DON'T want in a surplus!
I will also state for the record that the above is theory on my part and based upon my personal experience and the experience of others I have worked with who have used the product. Via empirical observation, it seems that the product can actually help you to build muscle while losing body fat.
My feeling is that your observation-based conjecture has merit. For newbies in particular, where some small muscle gain and significant fat loss can indeed coincide, I can see how the use of an insulin-resistance promoting thermo such as Nitor might be a way to enhance the effect, particularly under the conditions of a lower-carbohydrate or targeted-carbohydrate diet, correct training protocols and of course sufficient dietary protein intake.
