It can get a little carb centric. You do need to make sure you eat a varied diet, high in complex carbs. If you eat a good variety of fruits, vegetables, nuts, seeds, beans, legumes and whole grains you'll be fine. I know when eating on the run it's easy to just do the carb thing, but you'll feel better if you balance it out a little. Especially with Veggies. Lottsa veggies- They technically are carbs, but they are high volume, low cal, high in nutrients. If you eat a few servings of veggies with your hummus, pita, rice, beans, whatever, you'll be getting more nutrition, and also feel full faster without overdoing it. I find it easiest to do simple whole foods. Beans + rice + veggies in any combination works well for me, and has all the things you need, and with a few spices, you can make almost infinite combinations of food.
It does get easier. You'll find after a few months, it comes more naturally, and you'll have developed an arsenal of quick, easy, tasty meals to make. After a few years, it's as natural as breathing.
