Healthy days and not so healthy days?

i don't think you're really causing your body that much harm with your unhealthy foods, since it's not like you're eating a box of donuts and 5 servings of chinese food on your unhealthy days. you just have one indulgent meal. so i'd say you're feeling bad because your body prefers your healthy meals. perhaps little indulgences throughout the week would suit you better--like a cookie or a frozen cornmeal pizza (you can get them at whole foods, if you live near one...they're soo yummy and healthier than normal pizza)
