What are you eating? Choose healthier foods...? Cut down on pop, desserts, and vegan junk food if you eat these things.
Also how often do you actually eat? I know people who say they eat all day, but they actually eat less often than I do.
I really doubt you're protein deficient if you're eating all day, though.
