Hi, Colby, I can relate. Last year, when I was training for the marathon was the only time in my life I felt annoyed about "having" to eat. Seemed like it was constant. Craving sugar is often (IMHO) a sign of needing more protein. I know it's true in pregnant women, so why not in a woman who's breaking down/building muscle on a weekly basis? I agree with the advice to eat more often. Eat about every 2-3 hr. Walnuts and almonds are protein + good fat, and easy to carry, along with some raisins if you like. Those yogurt drinks they sell in the grocery store are easy, too, no spoon needed. Definitely make your midday meal a decent sized one. 200 calories is nowhere near enough for lunch when you're marathon training. L.
