I'm not a "health nut," but I eat healthy. I don't always take a full 30 minutes in the breakroom, but I eat during 99% of my shifts. The key is to bring several things to eat, none of them large. I usually have a snack around 2100, when I start my charting, then dinner between 0100 and 0300, depending on my schedule for the night and the stability of my pts. My lunch box always has a small leftover entree (think vegetarian pasta), a yogurt, and a cheese product (cottage, string, whatever I've bought), and usually a salad or some fruit. I eat the fruit/salad with either the yogurt or cheese the first time I get free time to chart, and then if my patients become busy or unstable I know that I've already eaten something that night. I take a full break later if they're stable, or eat at my station if they're not (I work ICU). Either way, I keep myself healthy by bringing in real food from home instead of hitting McDonald's or the vending machines. It's really not that difficult, and I've been doing it for a year and a half now. You just have to plan ahead, and prep some meals in advance. Good luck!
