It happens every year - a celebrity tweets about a diet and before long we're typing the key words into Google and replacing every item of food in our fridge.
We know it isn't necessarily the best approach to healthy eating, but there's no denying that these so called quick fixes can be very tempting.
In 2014 the Mediterranean diet and the Raw Food diet were big news, while the 5:2 diet continued to be popular both inside and outside celebrity circles.
But in 2015 expert nutritionists are predicting celebrity diet trends may take a bizarre and sometimes unhealthy turn.
The British Dietetic Association (BDA) have now released their annual list of the celebrity diets to avoid in the coming year.
From the utterly gross Urine Therapy diet to the downright dangerous Clay Cleanse diet, scroll through the slideshow to read all about them.

Celebrity Diets to Avoid in 2015
Urine Therapy(01 of05)
Open Image ModalCelebrity Link: Bear Grylls has reportedly drunk his own urine (for his TV show).What's it all about? Urine Therapy, or urotherapy, includes the drinking of one's own urine for cosmetic or medical/wellbeing purposes. Some claim that the urea component of urine can have an anti-cancer effect.BDA Verdict: Literally, don't take the proverbial! Emergencies, only as Urine Therapy has no scientific evidence that it adds anything beneficial to the body and its safety has not been established. As for any anti-cancer claims made in favour of Urine Therapy, this is simply not backed up by scientific studies. (credit:ASSOCIATED PRESS)
Paleo Diet(02 of05)
Open Image ModalCelebrity Link: Miley Cyrus and Matthew McConaughey have reportedly followed this 'diet'What's it all about? The Paleo diet (also known as the Paleolithic Diet, the Caveman diet and the Stone Age Diet) is a diet where only foods presumed to be available to Neanderthals in the prehistoric era are consumed and all other foods, such as dairy products, grains, sugar, legumes, 'processed' oils, salt, and others like alcohol or coffee are excluded.BDA Verdict: Jurassic fad! A diet with fewer processed foods, less sugar and salt is actually a good idea, but unless for medical reason, there is absolutely no need to cut any food group out of your diet. In fact, by cutting out dairy completely from the diet, without very careful substitution, you could be in danger of compromising your bone health because of a lack of calcium. An unbalanced, time consuming, socially isolating diet, which this could easily be, is a sure-fire way to develop nutrient deficiencies, which can compromise health and your relationship with food.

Sugar Free Diet(03 of05)
Open Image ModalCelebrity Link: Tom Hanks and Alec Baldwin have reportedly followed this 'diet'.What's it all about? The Sugar Free Diet is when you exclude all types of sugar (and often all carbohydrates too) from your diet.BDA Verdict: Not a total sweetener for success! We encourage cutting down on free sugars, adding sugar or products already containing added sugar, in addition to being label aware, because as a nation, we consume too much sugar on the whole. Some versions of the Sugar Free Diet call for you to cut out all sugar from your diet which is not only almost impossible, but would mean cutting out foods like vegetables, fruit, dairy products, nuts – not exactly a healthy, balanced diet. Also beware, substitutes some of these plans recommend like agave, palm sugar or honey, are actually just sugar in another form and a huge contradiction. (credit:Greg Allen/AP)
VB6 Diet(04 of05)
Open Image ModalCelebrity Link: Beyoncé and Dita Van Teeese have reportedly followed this 'diet'.What's it all about? The VB6 Diet (vegan before 6pm) of Chegan Diet (cheating vegan) is a diet that calls on you to follow a vegan eating plan most of the time/before 6pm, then after 6pm, nothing is off limits.DA Verdict: VB careful! By virtue, this should set you on course to eating during the day, at least, less processed food, more plant based foods like beans, pulses, wholegrains and nuts (watch your portion sizes) and much more fruit and vegetables which is a good thing overall as we should be aiming for at least 5 portion of fruit and veg a day and more fibre. Having said that, following a vegan diet doesn't automatically translate into a healthy diet. The danger here is, post-6pm becomes a window of opportunity to hoover up a myriad of foods high in calories, saturated fat and packed with added salt and sugar, undoing your earlier healthier choices. The reality is, eating different food groups at different times of the day doesn't matter, in terms of your health, its nutritional balance that's important. (credit:Evan Agostini/Invision/AP)
The Clay Cleanse Diet(05 of05)
Open Image ModalCelebrity Link: Zoe Kravitz has reportedly followed this 'diet'.What's it all about? A spoon of clay a day will remove toxins from the body and remove negative isotopes, helping you detox and stay in shape.BDA Verdict: Clay away from this diet! The Food Standards Agency issued a warning about clay after high levels of lead and arsenic were discovered in products saying: 'We remind consumers, especially pregnant women, about the dangers of ingesting clay, clay-based detox drinks and supplements'. The whole idea of detox is nonsense. The body is a well-developed system that has its own built-in mechanisms to detoxify and remove waste and toxins. Nuff said! (credit:Jordan Strauss/Invision/AP)
Speaking to HuffPost UK Lifestyle, BDA spokesperson and consultant dietitian, Sian Porter says our desire to follow a celebrity diet may come from pressure by the media, a longing to feel connected to the celebrity world and the yearning for an easy weight-loss solution.
"We are bombarded by this image of perfection that doesn't exist- most celebrity images are airbrushed or edited in some way. There's a lot of pressure about looks rather than health," she says.
"Everybody is looking for that magic bullet that's going to give maximum results with minimum effort, but I think deep down we all know that doesn't really exist."
It's important to remember that following some celebrity diets may do damage to your long-term health.
Porter says the best way to lose weight is to create a food plan that works for you, that doesn't cut out any essential foods or result in deficiencies.
"The whole mindset of 'I'm going on a diet' suggests it has a beginning and an end, and to lose weight healthily you have to make small, sustainable changes," she says.
"A diet that will work is a diet that you can stick to, as long as you're not harming your health in the process."
