What's your experience with keto for an already fit person to go from fit to shredded? I'm doing a fitness contest and while for now, I'm mostly just doing the old CICO/high protein approach, I am thinking ahead about how to take my results up a notch in the last few weeks. I always see obeasts singing keto praises, and have seen some smallfats get human on it, but I wonder if it's effective for someone who's already fairly lean.
