I don’t count calories. I’m so obsessed with numbers in other ways that it would be too much. I eat when I am hungry and I eat what I am hungry for. I don’t sweat the splurges, and my friends don’t judge me for eating all the things when we eat together.
If you’re interested in runner nutrition, I suggest “Performance Nutrition for Runners” by Matt Fitzgerald. He discusses he correlation between performance and body composition as well as fueling pre-, during, and post-workout. You could also check out these links:
