When you aren't already cooking for a spouse/kids, it can be hard to eat right (btdt). I always had my fave healthy snacks on hand whenever my dh was deployed. A fridge full of deli meat turkey, lettuce, celery/babycarrots whatever little things you can eat without cooking. Handfuls of nuts (in pre-portioned servings) yoghurts, cereal, stuff like that is easier to grab and convince yourself to eat than chicken breasts that require cooking and side dishes. I also like cup a soups, protein shakes, edamame and sweet peas (with salt and vinegar, yum!) and there are individual box servings of flavoured veggies in the freezer section at the commissary/walmart, I can't think what they are called but little boxes of flavoured veg you microwave. Again, it's an individual serving, and relatively healthy. Pack your cupboards/freezer with foods like this that require little to no effort and you'll find it easier to remember and easier to grab something to eat. Good luck!
