Giving this one in its own thread. It's the typical sort of nonsense that confuses lifters.
It's not possible not to have carbs before weight lifting. You can't utilize your stored body fat for energy in such a short amount of time (during weight training session). You need the energy that carbs provide you with. You should consume carbs about an hour prior to lifting... How can you say "0 carbs" before workout?!
I made a remark that I don't eat carbs before lifting, and haven't for about 5 years now.
