text: does anyone know why sometimes i pig out for a few days, then other days i cant eat anything at all? this happens to me alot... i would have 4 dayss of eating alot and feeling hungry all day then after that a few days where sometimes i forget to eat or im disgusted of food..btw: i hate drinking water and i feel like im gonna throw up after half a cup, it's a metabolism thing...you need to start regulating yourself and eating more regularly, both in time (eat at the same times each day) and in amount. ever wonder why you feel hungry right after a big meal sometimes? it's your metabolism speeding up to cope with a big meal and digesting quickly. then the next day you don't feel like eating anything because your metabolism is sluggish after the indulgence.  so, start eating more in routine, and the ups and downs of your appetite should regulate.
