Being vegan means no animal products and it means no one in your family will understand, which is probably the reason you did it in the first place. Not eating meat, fish, dairy or eggs is just the beginning. Vegan literature describes honey as off limits because it "enslaves bees." Famous vegans include Bill Clinton, who dropped a ton of weight and Anne Hathaway, who stopped wearing underpants. Maybe she dropped the panties because of the increased pooping?

This is a brilliant socially-acceptable way to say you want to eat anything that doesn't run away fast enough. This diet basically gives the middle finger to vegans, the planet and your arteries.

A pescetarian is a vegetarian that has no problem slaying and chowing down on things with eyes, as well as fins and tasty aquatic invertebrates. So while you feel the glow of not eating mammals, you are still going to feel like a jerk for depleting the ocean. The world's most famous pescetarian was the late Steve Jobs, which isn't exactly gonna sell a lot of people on the diet.

Choose this diet and expect to be eating a buttload of rice and fake cheese. Although the GFCF diet is often touted to help children with autism, the American Academy of Pediatrics wrote, "there is little evidence to support or refute this intervention, and reviewers have determined that meaningful conclusions cannot be drawn from the existing literature." Bummer. Mostly though, the diet is taken up by adults who desperately want to tell you about their special tummies and dubious allergies.

The problem with being a vegetarian is that it involves so much explaining. Are you doing it for ethical, political, environmental, heath or religious reasons? Are you ovo-vegetarian? Lacto-vegetarian? Will you avoid marshmallows because there may be hooves in there? We can see why you might go full-on vegan because at least then the world knows what flavor of nuts you are.

You could lump in all diets for religious reasons here. Basically, it's odd to think the almighty has enough time to monitor your snacks, but whatever floats your boat. We choose Kosher not because it annoys us, but because it's annoying to practice. You not only have to avoid certain animals and have others killed in the right way, you also need foods blessed in production and have an extra set of dishes. On the up side, bats are not kosher to eat, which probably won't cramp anyone's style.

People who practice this diet believe cooking food is bad for you. They believe heating food depletes nutrients and makes them downright dangerous. There have been many studies done on the pros and cons, but this diet can kill because when a raw foodie starts talking about their grub, you will want to throw yourself out a window.

While it's true we need sodium to live, too much of it can be dangerous. How much is too much is open to debate. New studies say that in some cases lower salt leads to higher risk of death. All we know is that those no-salt added soups make us want to give up on life.

The paleolithic diet is also known as the caveman diet. It instructs one to eat like the ancient hominids for better heath. But since our ancestors lived 20-35 years, should we be taking a page from their recipe book? Any hunter-gatherer would've set fire to their wooly mammoth jerky for even a taste of a buttered baguette.

It's like being a vegan except you can have some fish and have to chew your grains more. Two boosters of the diet, Michio Kushi and its founder George Ohsawa, smoked cigarettes. Kushi claimed lung cancer could be traced back to dairy products trapping the tars. We're not saying that's crazy... but we're strongly implying it.

A fruititarian makes a vegan look like a killing machine. In this diet you eat fruits, nuts and seeds but only if taking them doesn't harm the plant. Gandhi reportedly was able to practice this diet for five years. But that dude also drank his own urine every ding dong day. He not only wasn't picking veggies, he wasn't very picky, period.

According to Wikipedia, "Freeganism is the practice of reclaiming and eating food that has been discarded." It's a fancy way of saying dumpster diving. Some people who abhor waste do it for environmental reasons. Some people are just cheap, don't want to work and don't get grossed out easily. The author of this gallery has a freegan brother who fits into the latter category. He said the worst part about the recession was that delis now hold onto their sandwiches a lot longer. Remember that next time you pop out for lunch.

If you went low fat because your heart was screaming as loud as your doc, good for you. But there's a school of thought that the whole low-fat craze may have caused the obesity epidemic. In the 80's people were so concerned with fat as enemy that they carb and sugar-loaded. Check out the New York Times article "What Really Makes Us Fat" to make you doubt everything you know about calories.

Simmer down people who truly need to control sugar levels for medical reasons. This diet is only annoying when healthy people go on it and then ruin your summer BBQ telling everyone watermelon is a high glycemic food that should be shunned.

You are a vegetarian who occasionally eats meat? The vegetarians won't like you and the meat eaters will laugh in your wussy little face, but you're still probably more fun to be around than people who practice any of the other diets. (And hey, Thanksgiving with you doesn't make smoke come out of Aunt Ida's ears.) The only annoying thing is that you need a fancy name for not overdoing the meat thing, but if you must, go on with your bad self.
