I've recently moved to my grandparents' house for a while, I used to be able to just spend alot of time without eating and lost alot of weight. (which makes me feel good even though I know it isn't healthy.) But now I can't just lie about eating since they are home all the time. 

They make good meals and force me to eat, I make myself throw up afterwards, but I still feel like I'm retaining some food. I'm not done losing weight, yet. 

I guess my question is, is throwing up the same as not eating?

Sorry for wasting your time.
