Everyone has given you good advice. One more thing is don't be afraid to eat some "bad" carbs right after your workout. Bad meaning sweet potatoes or steel cut oats or something like that. Also you didn't say how much fat you are eating but for me, I eat 3-4 times the amount of an "average" Zoner. If you workout hard you need adequate fat and carbs for recovery. I think that may be why are noticing a strength loss. Sounds like you have a good handle on things but just need to tweak it.
