You would not lose weight. You would lose water. You would also damage your esophagus with the acid from your stomach. You would also become malnourished because you are not getting any nutrition. Then you would become sick and die. It's called anorexia.
If you only drink water, and don't eat anything, there is no need to vomit(as you will only vomit out stomach acid), you will already lose weight, and probably be hospitalized sooner or later from problems arising from nutritional deficits.
All of it.
You maybe would lose a little weight but as soon as you eat again your metabolism would kick in and you would start to gain the weight back and some more after that too . You don't have to starve yourself to lose weight . Exercise & lower your portions and then you will start seeing results. Starving yourself or purging are the worst possible ways to try to lose weight .
Vomiting to lose weight is always dangerous. There is no safe way to do it.
No. Starving yourself to lose weight is not safe, nor is it effective in the long term,for weight loss.
What a ridiculous question ! IF it were possible (which is ISN'T) why would you want to deliberately infect yourself with a parasite just to lose weight ?
You don't but you need to stop vomiting to lose weight or you will have bigger problems.
No ; but you won't gain any. But I am sure that you know that it's very UNhealthy...
You should never starve yourself to lose weight, this is very dangerous. A well balanced diet and exercise are the best ways to lose weight.
Lose some weight :)
Practicing habits like that, which are very dangerous to one's health and signs of eating disorder like anorexia and bulimia - which can be fatal - are not good, and WikiAnswers cannot promote such activities.
You need to see a psychiatrist to be evaluated for an eating disorder.
