The 6 Most Insane Crash Diets of All Time

The practice of throwing up after a meal is actually older than Hollywood and photographic airbrushing techniques, although Julius Caesar's attached psychological issues may have varied slightly from those of young women today. From accounts such as Cicero's, which explained how Caesar escaped an assassination attempt by vomiting after dinner in his bedroom instead of in the bathroom where his assassins expected him, it seems this sort of practice was common enough in Rome that no one batted an eye. Then again, so was watching a prisoner and a bear fight to the death for fun.

Now, people keep quoting "fun facts" about how ancient Romans threw up so much that they had special rooms to do it in, called "vomitoriums." Not so. While they did vomit a lot, and they did have rooms called vomitoriums, they were actually unrelated. Vomitoriums were just hallways in large stadiums where people exited all at once (so they "vomited" people out onto the streets when the event was over). Although, if they had just come out from watching a bear tear a man's arms off, they might have actually vomited in the vomitorium, but that would just be coincidence.

The Theory:
The idea is straightforward enough--to get rid of the food before you have time to digest it and turn it into fat. In the context of the Romans, they seemed to really enjoy eating and thought of it as a way to make room for more. They were type-A, impatient people who had a continent to conquer and couldn't bother with waiting for it to go out the other end.

The Reality:
By now most people are aware of the health consequences of repeated vomiting. But, just for the record, it causes tooth decay, osteoporosis, heart problems, kidney problems, damage to the esophagus, and fainting from low blood pressure. You know how when you throw up, it sort of feels like you're dying? That's your body trying to tell you something. Despite that, people still do it and we call it bulimia.

The Results:
Caesar was, as you probably know, murdered before any of these symptoms really had a chance to show themselves. As for others engaging in the practice at the time, we're not sure, since complaints about bulimia symptoms probably would have gotten lost in complaints about syphilis, gout, parasites and the other 5 million diseases people picked up by age 30 back then.

These days, we've figured out that the practice can make you die, so on the scale of sensible diet solutions it's about the same as sticking a bear in your kitchen to keep you from getting to the fridge.

The Results:
While a fair amount of people were pretty sure Graham was insane, others bought into his philosophy, which didn't cause much ruckus as long as they were only putting themselves on the diet. However, in 1840, the leadership of Oberlin College was convinced to adopt and enforce Graham's diet on its student body.

Dissatisfaction reached a turning point when one professor was fired for scandalously bringing a pepper shaker to lunch. Things went downhill after "Peppergate," as the press at the time would not have called it, and the grand experiment was canceled.

Graham's legacy was a bland, tasteless whole-grain cracker he invented as a staple of the diet, which became known as the "Graham cracker," a name so clearly evocative of delicious flavor that Nabisco later named its completely different, enriched-flour, honey-flavored cracker after it. Due to the extreme changes from the original recipe, modern-day Graham crackers no longer have the ability to cure lustful thoughts.

Fletcher felt it was very important to know exactly what was going into your body, and that one of the best ways of evaluating this was to examine what was coming out of your body. He advocated teaching kids to inspect their own "product" after defecating to be sure they were eating a healthy diet.

The Reality:
Reasonable experts, today, still suggest you take your time to chew your food, as it's a good idea not to send huge chunks down to the stomach. And, eating slower isn't a bad idea if you're looking to lose weight.

However, the problem with Fletcher's diet was that there are some components of food, like fiber, that don't break down into liquid despite all attempts at frenzied mastication. Fletcher's solution was not to eat fiber. This may explain why people were known for being uptight in the Victorian era.

Extensive scientific studies at the time also concluded that examining your own poop is gross.

The Results:
Fletcher lost a lot of weight, and at age 58 allegedly beat a number of college athletes in physical fitness tests in a staged event that he set up. On the other hand, he died of a heart attack.

Fletcher also had a good friend by the name of Dr. John Harvey Kellogg who was on board with his diet and even made up that stupid "Fletcherizing" term. However, the one thing Kellogg did not buy into was the no-fiber rule, so much so that he was inspired to invent a high-fiber breakfast cereal known as "corn flakes."

Fletcher's only other legacy is chewing, which people would no doubt not be doing today if it hadn't been for his amazing discovery.

As humans gained knowledge about tapeworms, parasitic worms that attach themselves to the digestive system of a mammalian host and consume its nutriment, most people observed that this was horrible and disgusting. However, demonstrating that female body image problems are by no means unique to our time, some desperate women skimmed past the words "worm," "parasite," "lay eggs inside your digestive system," "severe health danger" and pictures of this:

... and fixated on the phrase "causes severe weight loss."

The Theory:
The idea is that if tapeworms are digesting your food, you're not. You can eat as much as you want and this will go into the worm's tummy, not yours. The tapeworm will get fat and become an outcast in tapeworm society, but that would be its problem, not yours.

The Reality:
What do you think the worm is doing with all that food? It's not a dimensional portal. That worm is using the food to grow bigger and stronger, and maybe lay some eggs. Although most people with a tapeworm in their guts do not show any symptoms, the tapeworm is probably consuming some vitamins and nutrients you need, and has been known to share with its hosts the gifts of diarrhea, nausea and bloating. But that's not all! If the larvae manage to spread to other tissues in your body, such as the nervous system, they can affect your brain, or cause seizures, meningitis or dementia.

Also, if you are having a good time and forget about the worm for a while, don't worry! It will remind you by shedding segments of itself to show up in your poop.

A tapeworm is kind of like an acquaintance you agree to room with because you don't know them that well. They seem nice, and they will be a good workout buddy for you as you try to lose weight, but after a month, they are using your toothbrush, drinking your milk out of the carton, and following you around on dates saying how nice it would be to wear your skin.

One would think that it's not necessary to point out that there are drawbacks to having a disgusting meter-long parasite embedded in your intestines, but apparently some people need it said.

The Results:
After decades of observing ill-health effects and complications, not to mention the difficulties in removing the tapeworm when all is said and done, people now realize the foolishness of this method and--oh, no, wait, they're still doing it.
