(Relaxnews) – As we get closer and closer to the end of 2012, let’s take a look back at some of the craziest, not to mention least effective diet fads which our fave celebrities tried in their never-ending efforts to fit in with the Hollywood glamour. The fads included diets encouraging our celebs to sit in a cold bath until 10 am, binge drinking, and passing a feeding tube through the nostril in order to pump a liquid formula into the stomach. Let me just say, no thanks, and pass me the cookies.

What is at the top of the British Dietetic Association’s list of the worst fad diets to avoid? The famous protein-heavy Dukan Diet popularized by celebrities such as Carol Middleton (mom to Kate Middleton), Jennifer Lopez and Gisele Bundchen comes in at the worst diet craze of the year.

Here are the top five worst diets popularized by celebs in 2012 (according to the British Dietetic Association):

5. The 6 Weeks to OMG Diet

The diet calls for skipping breakfast, exercising first thing in the morning after drinking black coffee, then sitting in a cold bath to encourage the burning of stored fat until 10 am. Snacks and fruits are off limits, foods are protein-heavy and carbs can come from cola or broccoli. Any diet which allows colas should send off an immediate red flag.

4. Alcorexia or Drunkorexia Diet

Basically, a diet based on alcohol and little else. Followers save their caloric intake from food and instead get their calories from beer, wine, spirits. Not hard to find the madness in this. And why follow a diet which sounds eerily similar to anorexia.

3. ‘Party Girl’ IV Drip Diet

Followers of this diet get hooked up to an IV drip rich in vitamins like B, C, magnesium and calcium, a misguided principle given that the best sources of nutrients are in fiber-rich foods. Side effects can include dizziness, infection, inflammation and anaphylactic shock. The combo of dizziness while plug to an IV is enough to blacklist this diet for me.

2. The Ketogenic Enteral Nutrition Diet or KEN

For 10 days, followers are banned from eating and are hooked up with a feeding tube through the nose that pumps a liquid formula into the stomach. Dieters must carry the pump and liquid wherever they go, most likely in a bag or backpack, and can only unhook themselves for an hour a day to drink water, tea, coffee or sugar-free herb teas.

Seriously? And this came in at only #2? I hate to see what #1 is…

1.  Dukan Diet

The diet which trumps IV drips, feeding tubes, cold baths and alcoholic regimes is perhaps one of the most popular diets around the world. Simply called the Dukan Diet, the regimen created by French physician Pierre Dukan bears striking similarities to the Atkins diet for being protein-heavy. According to the BDA, the diet is confusing, time consuming, rigid, and hard to sustain. Side effects are likewise unappealing, with everything from lack of energy, constipation and bad breath. Next time you envy the svelte bodies of Jennifer Lopez and Gisele Bundchen — just imagine their horrid breaths and appreciate your awesome self as you are. Unless you have bad breath.
