Gotcha. Since leaning out and conditioning are your primary goals, carb timing is probably less important than if you were doing traditional BBing-type training. Instead of carb timing, I would concentrate on calorie control. Now, it so happens the easiest way for me to control calories is to keep carbs low. Like most people, I find fats and protein more filling/satiating, and (like some, but not all, people) I find carb intake makes me hungrier. For me, carb intake tends to beget more carb intake.
If you don’t want to go full-on low-carb (and who could blame you–it kind of sucks), one technique that has worked for me in the past–and that I think I might employ if I were in your situation–is called The One Hour Window. Per this approach, you would eat low-carb all day (including before and after your two conditioning workouts). However, at dinnertime, you’re allowed to eat carbs, the rule being that you complete your carb intake over the course of one hour. This technique minimizes insulin release, but still allows you to indulge your ‘carb tooth.’ Note that the one-hour window should not turn into 60 unbroken minutes of nonstop carb-gorging. Rather, eat a normal meal’s worth of carbs; just make sure you’re done eating them within an hour. This rule would apply to off-days as well. So long as you keep total calories in check, this technique will allow you to lean out nicely.
Anyway, consider giving it a try. Whatever you decide, please give us an update at some point and let us know how it’s going. And thank you for your service.
