text: 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.\n\nSo, start eating more in routine, and the ups and downs of your appetite should regulate.
