I agree with the recommendations to get your calories up, as the level at which you're consuming risks slowing your metabolism (automatic way your body compensates for what is perceived as starvation). Make sure you're eating healthy whole foods emphasizing foods that contain healthy fats and above-ground vegetables. With the right combination for you, you will continue to progress without feeling hungry or sluggish. Remember, no one can tell you what your optimum caloric level should be. We're all different, but there are common ranges that serve as useful guidelines. You'll find your optimum level at some point with patience and eating the right foods.
