What you need is an In-Case-of-Emergency-Break-Glass plan that saves you—but only if there's something of value behind the glass. Otherwise, you're just left with an additional mess to clean up amongst all the other chaos.
So, take steps now to plan for when your plan falls through. Help yourself expect the unexpected. I mean, you know it’s going to happen. Not preparing it for it is giving up before you even begin; it is—let’s be frank—preloading excuses for your lapses. (“Well, I was going to ace my nutrition today…but something Important came up. Really, it’s not my fault; there was nothing I could do about it. Really.”)
What you know is that the contingency plan has to be reasonable, speedy, and, depending on your circumstances, perhaps non-perishable. Come up with some snacks and meals that you know you can keep on hand. Or even parts of meals, with a plan to complement them with things you know you can forage for even under the pressure of deadlines, tight schedules, demanding children, and the mid-afternoon munchies.
That might mean that you keep a can of tuna, sardines, or bag of jerky for your protein and then head for the cafeteria to scare up a garden salad or a random piece of fresh fruit. Or, keep the carbs handy in the long-shelf-life form of a Lara bar or a small quantity of dried fruit.
If you keep some reliable staples on hand as a regular practice, you can always toss together a few blocks of balanced fuel on a moment’s notice. Stock the fridge at the office with some of the following, and you’ll be set for even the unplanned meals and snacks you might need. Keep nuts on hand (macadamias have an excellent fat profile), or even a small bottle of olive oil, to make sure you can get a small fat dose with any meal.
