Without knowing your current stats (height, weight, bodyfat) I'm just wildly shooting in the dark here. But unless you're a really small person that's not a lot of calories, and that's a pretty low ratio of protein. Wild guess would be a more protein, bringing your overall calories up and giving you a ratio in the ballpark of 10%carbs/40% protein/50%fat.
You might be shutting down your metabolism by eating too little. Are you hungry all the time? Do you feel comfortable after eating?
