dont worry about some extra food you going to be safe.
i had a bad day last Sunday and just made myself an omelet with tuna and bit of mushroom.
instead of normal day you had (I'm guessing) around 20 hour run day and night. It's absolutley normal you will need some more calories.
Keep strong and don't let that one understandable slip ruin your goal.
btw
There's a scientific fact wich explains why we crave for food when we stressed!
-----"Stress: Not Just "In Your Head"
While we tend to view stress as toxic to our minds, we generally don't consider its potentially harmful effects on the body. But the physical effects of stress are profound.
During times of stress, your body gears up to take action. This "gearing up" is called the fight-or-flight response, and it's what causes your heart to beat faster, your breath to quicken, and your stomach to knot. It also causes the skyrocketing of many hormones-a signal to flood your cells with the energy they need, in the form of blood sugar and fat, to deal with the threat.
Stress plays a direct role in how your body responds to the hormones that raise blood sugar levels. "Under stress, your body goes into fight-or-flight mode, raising blood sugar levels to prepare you for action," says Richard Surwit, PhD, author of The Mind-Body Diabetes Revolution and chief of medical psychology at Duke University in Durham, NC. If your cells are insulin resistant, the sugar builds up in your blood, with nowhere to go."------
basically, more stress - more sugar in our blood.... sugar we don't have. Because of that we handle it bit on the negative side.
F*** sugar, we have minimins
