7. Tapeworm diet



Sounds gross, doesn't it? It certainly is! People on this diet ingested tapeworm eggs, which grew into long worms that lived in their digestive systems. The worms decreased appetite and interfered with the absorption of food, thereby enabling weight loss. Once the person reached their target weight, they would take medicines to help them expel the worm.

8. Red Bull diet



A woman in New Zealand invented her own diet in order to lose all her post-pregnancy weight. She drank about 14 cans of Red Bull per day, and ate only a little bit of cereal now and then. She had a heart attack shortly after and still suffers from severe cramps, anxiety attacks and heart issues.

9. Wine and eggs diet



The basic components of this diet are eggs, wine and black coffee, with a couple of other fruits and supplements thrown in. It was developed for lazy or busy people who love wine and cannot give it up.

10. Sleeping beauty diet



If you're not awake you can't eat, right? The sleeping beauty diet puts its victims under heavy sedation for long periods, to enable weight loss!

11. Fletcherism



This one isn't a diet exactly, but rather a way of eating that was developed by Horace Fletcher. Slow eaters tend to eat less than fast eaters, because it takes the brain about 20 minutes to realise that the stomach is full. But Fletchism takes the concept a little too far. Fletcher recommends that you chew each bite 100 times, until it is liquefied, in order to lose weight.
