This diet sounds reliable… until you realise that just drinking lemon water for 10 days can turn you into a skeletal mess.

Its origins date back to the 1940s, and became mainstream in 1976 with Stanley Burrough’s book, The Master Cleanser. Several Hollywood stars claimed to have tried it with huge success and the diet went viral online.

But what this diet does on top of cutting your body mass, is depriving your body of the essential nutrients it needs. Those who’ve tried the diet for up to 40 days have reportedly become so weak that they can’t even move. So no… this one’s not worth trying.

Its creator, US celebrity personal trainer Tracy Anderson, describes it as “a cleanse where you still eat” and stars such as Jennifer Aniston and Lady Gaga were said to be on it.

You basically eat only one meal a day and replace the other two with several jars – up to 14 or 16 of them, according to some sources – of baby food.

However, baby food lacks fibre, so you’re not doing your digestive system any favours.

Also, not all baby foods are low in calories and what you eat in your one “grown-up” meal affects the end result too.

Naturopath Dr Peter D’Adamo came up with this diet and even wrote a book, Eat Right For Your Blood Type, which became a New York Times bestseller.

The diet follows the premise that people of different blood groups should eat different types of food, as our genetic make-up makes us predisposed to certain sicknesses so we should eat the right foods to lower these risks. However, there is no actual scientific evidence to back this up.

Just the name of this one alone sends shivers down our spines.

Famous stars like the opera legend Maria Callas and supermodel-host Tyra Banks have reportedly tried this diet. 

You consume a “worm egg pill” which hatches in your digestive tract and latches onto your intestinal wall. As the tapeworm grows it will start to “feed off” the nutrients from the food you eat, so that your body does not convert these into fats. The diet goes on for a few months until you’ve reached optimal weight and then you have the tapeworm removed from your body with medication and it passes out of your body.

If just reading the above description does not put you off, we don’t know what will…

Victoria’s Secret model Adriana Lima is a big fan. Unfortunately, we all can’t look like her just by following it.

The rules of this diet? Drink several ready-to-drink fruit and vegetable juices throughout the day, up to six a day.

While there’s a high chance that you will lose weight, what you’re actually shedding is water weight, not fat. And it’ll be really easy to put it back on once you’re back to solids.

If you want to follow this seven-day diet, you’ll have to eat cabbage soup every day.

While cabbage soup is low in calories and fat, it’s also not packed with nutrients, which means you’re not going to have a lot of energy.

And because the soup is so bland, there’s a high chance that you’ll reach for flavourful foods – which often equals to salt and sugar – once you’re done with this diet.

So unless you have the willpower to eat healthy after you end this diet, it’s not going to be of much use.

Reportedly made famous by Elvis Presley, the rationale of this diet is that if you’re asleep, you can’t eat, so you’re not going to put on weight as your body works to burn off the calories that you have stored.

Also, studies have shown that a lack of sleep results in an increase in body fat, so the more sleep you get, the less fat there’ll be in your body, right?

Well, wrong, actually.

Going for a long period of time without food can damage your body, and depriving your body of any physical movement is detrimental to your health too.

Once you take into account the dangers of sleeping pills or other sedatives, you’ll realise that this diet really isn’t good for you.

We’ve saved the craziest – and most dangerous – diet for last.

All you have to do here is dip up to five cotton balls in orange juice or lemonade and swallow them.

It’s meant to curb your hunger so you’ll stay away from unhealthy foods, and you’ll also feel full without a high calorie intake so you won’t gain weight.

The fact that you’re actually ingesting cotton balls should tell you what a bad idea this is.

You could choke on them, plus you’re getting none of the nutrients that your body needs to function properly.

Don’t try this at home!
