Tapeworms are not a sane or reasonable method of obtaining weightloss. They may carry rather nasty illnesses as well, being creatures that live in the intestines.
You need to find a way to alter your diet to lose weight instead of ingesting filthy parasites. A visit to a mental health professional might also be a good idea.

tapeworms r mostly found in meat if u don't wash ur hand after touching the infected meat or if u eat unproperly cooked meat,ur possibility of getting tapeworms is very high.u can use it 4 lossing ur weight as this isn't the right way n very risky to do that too,better u do more exercise 4 settling ur weight loss.

your discusting do you know it comes out your *** in the future, you can get it from eating raw fish that have paracites.

Getting any type of parasite or illness in order to lose weight is a really, really bad idea. If you would like to lose weight, why not just exercise and eat healthy?
Concentrate on health first and appearances later, it's easier to be happy with yourself when you're healthy than it is if you're the host to parasites.
