Tapeworms
Unfortunately, you can buy pills with tapeworm eggs inside to purposefully swallow them. The idea behind this dangerous fad is that a tapeworm will “eat” the food you consume, making it possible to lose weight while eating whatever you want. It sounds too good to be true because it is.
A tapeworm is a parasite — and you do not want a parasite living inside you even for a short amount of time. Healthline says tapeworms can disrupt organ function, block bile and pancreatic ducts, and enter and damage your brain.
