Dear Jacinta, It is really dangerrous to throw up after you eat, you could become anerixc or lots of other things. And staving will make you thin but when you start eating again youwill gain back allmost everything. So you should exercise like walk each night, cut down on your food ( I have to work hard on that part),make a rule about junk food like I do only on the week-end( that means chocolate too), and drink lots of water. It works for me I've lost 5 pounds. And it doesn't take that long if you are set on doing it. You can do it! You just have to believe in yourself. Hope I helped.Bye Melanie
