What is the worst way to lose weight quickly?

I was reading a site about eating disorders, so short of bulemia and anorexia, what are the worst ways to lose weight? Weight has to be lost quickly, and it cannot be "eat less, exercise more-lose 1-2 lbs/wk." This questioned does NOT concern any one in particular, as I am just curious about some of the crappiest ways people have gone about trashing thier health.Crappy ways:So called liquid diets.Replacing meals with vitamin pills.Taking diuretics or laxatives.Can't help you with scources.All my info is from stuff I've seen idiots, I mean people put themselves through.The absolute worst way to lose weight is to stop eating. The best way is to eat healthy foods in moderation and combine a mixture aerobic and anerobic (spelling?) excersize into your daily routine
