Im lactose intolerant. eventho i watch intake, iget diarrhea sometimes if i overdo it, does my body excrete the food just ate along w/those calories?

Lactose intolerant: If you are lactose intolerant, you will have diarrhea and/or other symptoms every time you eat dairy products. Your body will retain some of the other food, but you'll be losing some nutrients and electrolytes from the diarrhea. There are other milks available -- such as almond, coconut, and soy. Some people use lactaid (lactose free) products too. http://www.lactaid.com/products.
