Note to self: eat something BEFORE workout. I went to the gym at 2 after only having had breakfast, and what a mistake. I had no energy, dragged my ass through 25 minutes of cardio and 1/2 hour of weights, and staggered back home, where I ate double my alloted calories for lunch. Bad deku.
But on the plus side, I did work out, and I'm still under my daily calorie requirement.
