In Precision Nutrition, John Berardi has a whole seciton on how to sneak calories in or out of your diet. For instance, if you're eating 1/2c. 1% cottage cheese, switch to 4%. It's easy to do with dairy. It also looks like you could add in some more carbohydrates - a whole wheat roll would add in 140 or so calories, easy. Or you could do a piece of toast with breakfast, or an extra banana here and there. Add in some almonds, walnuts, or flaxseed meal.

30% carbs is pretty low carb in the grand scheme of things. You should feel free to play around with your macros to find what works best for you.

When you eat more, you may find you get hungry for the additional food. Your metabolism adjusts upward with food intake if you've been undereating. Eat more, and your body will respond to that additional energy, especially if you're using it.

If you'd like really specific advice, why don't you post what you ate yesterday or today? There may be easy ways to sneak in some additional calories without adding to the volume of your meals.
