I'm going to comment line by line for the discussion here. Please tell me if doing it this way is too confusing
I agree with everything you wrote. IMO part of the reason I don't get fat is simply carb timing and the use of short acting insulin. I only use Humalog, which is in and out in roughly 4 hours, whereas a diabetic uses insulin all day.
The thing is the only source of insulin a diabetic has is what they are injecting (assuming Type I insulin dependant diabetic, type II's are a bit different). What I think is happening is you are taking exogenous insulin, your body is not sensing hyperglycemia as a result of that insulin keeping blood sugar in check, so you aren't secreting insulin while its being metabolized. It's out of your system relatively quickly, so then your "normal" production returns.
In my case I take Humalog first thing in the morning with a preworkout shake, train with another shake, drink my post workout shake and then wait 45 minutes before eating a solid carb/protein meal. The rest of the day is simply protein, fibrous veggies and EFAs.
Like i said above, you are taking in substantial carbohydrates in a relatively short period of time. The exogenous insulin will be used first to metabolize these carbs---this is to fat and muscle cells, so dont forget that. The thing is your deficit the rest of the day probably is a huge factor also. I have to wonder if you arent going to reach a point with that approach where you are going to actually inhibit muscle growth over time. Remember, most strenght and size gains occur hours after you are out of the gym. I dont' know this, its just a thought.
The other thing I'd like to see is what your blood glucose levels relative to your endogenous insulin levels are doing during this time--like an every 5 minute blood glucose curve. Blood glucose is a dynamic entity, meaning it goes up and down all day long within that tightly controlled normal range. Consuming 400 grams of relatively simple carbs over a 2-3 hour period will drive it up slightly even in a nondiabetic. Not consuming enough carbs with the exogenous insulin may be resulting in subclinical hypoglycemia.
I'm actually surprised you dont' have a 'rebound" collapse from this approach.
IMO the fact that I'm training certain muscles and blood flows directly to those locations is another part of the reason the carbs go there over fat. IDK, but it works.
I can eat 400g of carbs around my workout without a problem. If I didn't use insulin and spread those carbs out over the day, I would get fat as hell.
I don't know.
Adding in GH, T3 and Anabolics, even at relatively low doses has a huge synergistic effect. I recently jumped about 15lbs in weight and got leaner at the same time. It was the first time I had used all those compounds at the same time so that's probably part of the reason I had such a good reaction.
GH and anabolics have an insulin desensitizing effect (GH more than anabolics, but anabolics at certian doses do), so this comes back what I've been saying with bodybuilders taking drugs that inhibit insulin function.
To me this gets very, very complex with many small variables that need to be considered.
