It would seem through peoples expereince here that if you are doing a crossfit type workout and getting enough protein VLC seems to provide all the energy you need. Increasing carbs seems to offer no advantages.
If you are lifting weights to failure or near failure it would seem that increasing carbs does offer an advantage in both recovery and the actual lifting.
You will get different answers from everybody here.
For me, I can't lift at the intensity I like when I am under 50g of carbs and I am sore/tired all the time. Over 150g though I start to get ravenous all the time. I just need to eat and at that point it does not matter what.
So I keep carbs around 75g except for the 2 days I go to the gym I up it to over 100g but below 150g.
I always assume people know what I am talking about. Big mistake.
Not that I think you should know what I am talking about. Bah! See what I mean haha!
