Low-Carbing When Life Hands You Lemons

I read somewhere once that the key to maintaining a low-carb lifestyle is taking advantage of the heightened energy you get from having a stable blood sugar in order keep up the hard work of planning and preparing more healthy food so that you continue the process. It made total sense to me, since sugar and carbs make me feel way too sluggish and lazy to even think about spending time in the kitchen.

For the last week, though, I've been under the weather with a nasty cold, and until yesterday, I've been all too happy to use my lack of energy as an excuse to go back to eating fast food, sugary treats, and instant boxed meals. Part of me knew that eating better would probably make me feel better faster, but the thought of toiling in the kitchen while in my drowsy, congested, cold-medicine-induced state was so unappealing that I just gave in to the temptation to get food in the easiest way possible.

So how do you stay on track when you're thrown for a loop? Are there any strategies you use when you find yourself in a position where you have little time or energy to plan for healthy eating? Or if you allow yourself to slip a little when life gets tough, how do you get yourself back on track?
