How to not let your parents or friends find out your not eating? Please read?

I'm fat. Everytime I look in the mirror all I see is that I'm fat. I want to stop eating and I plan on doing so I'll still have to eat dinner tho because my mom will make me! But all of the other meals she won't know if I ate them or not because she is at work! I really don't want to eat dinner but I plan on eating just a little, i know I have to eat something or else I can die, but when I'm at my friends how what do I tell them when I don't want to eat? Because I don't want them to find out I'm not eating I don't want them to worry about me. I play soccer so I realize I still need to eat a little which is why I'm eating dinner. If I'm eating dinner I won't pass out or get hospitalized right?! I don't want tohage to go to some gay treatment center over the summer or during the school year!! I think 1 meal is fine and I will stil lose weight. & don't go into crap like I'll gain weight and "your body goes into starvation mode" because I've heard stories from people who don't eat and they say you do lose weight!
