The world's top ten best (worst) fad diets

Cabbage soup, tapeworms and imaginary food - all healthy and effective ways to lose weight, if you believe the women's magazines.

Being as you are a bunch of keyboard-pestering internet potatoes, you will all undoubtedly know how notoriously difficult it is to lose weight. Oh, would that becoming your lithe, slimmer self were as simple as the mere task of burning off more calories through exercise than you take in through cheese snaffling! Unfortunately, and despite what mendacious vegetable-eating tosspot Jamie Oliver would have you believe, combining a healthy diet with regular physical activity barely makes any difference to your flabby, gelatinous arse, which is why you should accept that chowing down on your five-a-day and frantically zumba-ing your way to a slimmer, sexier you whose thighs don't rub agonisingly together as you walk is a fool's errand. Instead, why not try one of those totally non-mental faddy diets, brought to you courtesy of Every Women's Magazine Ever?

The Cabbage Soup Diet

This classic diet is a must-try for every slimming masochist. Everyone knows that cabbage smells like arse, but not only does this diet make you shit molten cabbage-lava, it also makes your house (wherein you have been preparing the devilish concoction) extremely unpalatable to gentleman callers. If you've been craving celibacy as well as IBS, and are prepared to eat unparalleled quantities of boiled cabbage (perhaps you are Russian?), then this is the diet for you.

The French Women Don't Get Fat Diet

Hear that, ladies? No French woman has ever experienced the indignity of portliness, despite the fact that this is a nation that eats cake and cheese for breakfast and whose lunchboxes contain pig's head fried in butter. Apparently, this is because these women are able to enjoy the country's gourmande delicacies, such as baked camembert, in moderation, while spending every weekend subsisting on leek water (a mild diaretic) until they poo themselves thin. How the French have managed to combine faecal incontinence with a reputation for chicness remains one of life's great mysteries.

The Lemon Detox Diet

Starvation is the name of the game, with dieters replacing food with a lemon juice and maple syrup mixture that can ultimately rot your teeth and constipate you. This diet will not only make you unpopular when you visit restaurants with friends and order hot water for your "mater cleanse lemonade", but is also based on what Dr Ben Goldacre probably calls "unadulterated detox bollocks". You're unlikely to lose anything except water-weight before your body kicks into starvation mode and starts clinging onto every last molecule of fat like a toddler to a shinbone on the first day of school.

The Dukan Diet

Offer someone on the Dukan Diet a sausage sandwich and they will probably reply "No. I'm on phase two of the Dukan Diet and can only eat pork on every second Wednesday providing it's a full moon." The reason for this is that the vagaries of the Dukan Diet and its various phases are harder to grasp than the most complex branches of theoretical physics. Even the Schrodinger's cat thought experiment (which, let's face it, most people only pretend to understand because - SPOLIER ALERT- barely anyone's brain can comprehend a cat in a box that is simultaneously both dead and alive) is liable to become as unchallenging as an episode of Button Moon when compared with a Dukan dieter trying to work out whether they're allowed yoghurt on Tuesday. From what we have been able to glean from the esoteric mumblings of the Daily Mail website, the Dukan Diet is based mainly around cottage cheese and allowed Suzanne Southall from Birmingham to lose seven stone, which, considering the fact that cottage cheese is composed entirely of the cellulite waste removed through liposuction, deserves a famous paradox all to itself.

The Tapeworm Diet

If you're one of those women with a big event coming up and are praying for a spot of slimming Norovirus to help you on your way (hot tip: try the oysters at the Lord Stanley), you could do a lot worse than a tapeworm. How exactly you're supposed to go about 'catching' a tapeworm doesn't really bear thinking about (although according to our research on the internet it invariably involves giving a Mexican $1,500 - a bit dear considering pig shit costs nothing), but once you've got the bugger in it can apparently lead to a weightloss of 1-2 lbs per week. Side effects may or may not include the tapeworm bursting out of your stomach while you lie on a spaceship breakfast table after an artificially induced deep sleep. Speaking of.

The Sleeping Beauty Diet

This crackpot diet has been being peddled for over fifty years, on the basis that your body is forced to use up extra reserves of fat while you sleep. Perfect for the ultimate lazy dieter, it involves the bare minimum of effort and crops up regularly in newspapers and women's magazines. When taken to an extreme conclusion, however, this diet involves 24/7 sleeping following medically- assisted sedation, in order to get your abs fairytale firm. Yeah. Expect to awake from your three day Temazepam snooze to discover that you are not only 12lb lighter, but that a homosexual in a cape is leaning over you, clutching an engagement ring as he wet-breathes on your face.

The Hallelujah Diet

The regime of choice for Bible-bashers, this diet is based on something God apparently said in Genesis about how 85 per cent of your food should be raw and plant-based, or something (it's essentially veganism with added sanctimony). It's not the most balanced of diets, revolving as it does mostly around mung beans, and flagrantly ignores the fact that cooking kills off some of the bacteria that lives in food. God also later renegs on the veggie-deal by saying: "every living thing that moveth shall be meat for you", which basically means that you can go ahead and eat that tapeworm mentioned earlier.

The Air Diet

Perhaps tiring of their daily leek juice, a couple of years ago French Grazia featured the Air Diet, an eating plan which involves.not-eating. Basically, you hold your food up to your mouth but instead of consuming it, you just pretend (to yourself and others) to be. It's a regime that sounds even less satisfying than the well-publicised Mastication Diet, involving involves chewing food before spitting it out. Whether or not the magazine were engaging in self-referential post-modern irony by covering this remains something of an unanswered question, but considering that the same article featured a recipe for "water soup" which apparently helps you "lose four dress sizes before the summer", we can only conclude the answer to be no.

The Purple Diet

This diet involves the unique consumption of only purple food (can you tell that we're losing the will to live?)

The Liquid Diet

This is the part where, after exhausting all dieting options, you drink two bottles of Pinot and four tequila shots, while weeping to your best friend about how your life is so miserable and devoid of joy and chocolate mousse that you have become an empty husk of a person. In a sense, you have become a human Shrodinger's cat- alive, yet dead, and in a box filled with cyanide.

Which brings us to The Serious Bit - while we may have been flippant earlier on, a very important point lies at the very heart of this poor excuse for an article. Which is this: next time you think of embarking on a fad diet, you need to ask yourself why so many of them exist in the first place. Surely if such a diet worked then the pseudoscience diet fascists would have stopped their evil schemes long ago? Aside from their vested interest in keeping you fat, these diet gurus (and the magazines that publish them) care little for your health and wellbeing. This is less amusing than it is terrifying once you realise that health is really all you have.

Will Euroscepticism prove an unbeatable advantage in the Conservative leadership race?

Conservative members who are eager for Brexit are still searching for a heavyweight champion - and they could yet inherit the earth.

Put your money on Liam Fox? The former Defence Secretary has been given a boost by the news that ConservativeHome’s rolling survey of party members preferences for the next Conservative leader. Jeremy Wilson at BusinessInsider and James Millar at the Sunday Post have both tipped Fox for the top job.

Are they right? The expectation among Conservative MPs is that there will be several candidates from the Tory right: Dominic Raab, Priti Patel and potentially Owen Paterson could all be candidates, while Boris Johnson, in the words of one: “rides both horses – is he the candidate of the left, of the right, or both?”

MPs will whittle down the field of candidates to a top two, who will then be voted on by the membership.  (As Graham Brady, chair of the 1922 Committee, notes in his interview with my colleague George Eaton, Conservative MPs could choose to offer a wider field if they so desired, but would be unlikely to surrender more power to party activists.)

The extreme likelihood is that that contest will be between two candidates: George Osborne and not-George Osborne.  “We know that the Chancellor has a bye to the final,” one minister observes, “But once you’re in the final – well, then it’s anyone’s game.”

Could “not-George Osborne” be Liam Fox? Well, the difficulty, as one MP observes, is we don’t really know what the Conservative leadership election is about:

“We don’t even know what the questions are to which the candidates will attempt to present themselves as the answer. Usually, that question would be: who can win us the election? But now that Labour have Corbyn, that question is taken care of.”

So what’s the question that MPs will be asking? We simply don’t know – and it may be that they come to a very different conclusion to their members, just as in 2001, when Ken Clarke won among MPs – before being defeated in a landslide by Conservative activists.

Much depends not only on the outcome of the European referendum, but also on its conduct. If the contest is particularly bruising, it may be that MPs are looking for a candidate who will “heal and settle”, in the words of one. That would disadvantage Fox, who will likely be a combative presence in the European referendum, and could benefit Boris Johnson, who, as one MP put it, “rides both horses” and will be less intimately linked with the referendum and its outcome than Osborne.

But equally, it could be that Euroscepticism proves to be a less powerful card than we currently expect. Ignoring the not inconsiderable organisational hurdles that have to be cleared to beat Theresa May, Boris Johnson, and potentially any or all of the “next generation” of Sajid Javid, Nicky Morgan or Stephen Crabb, we simply don’t know what the reaction of Conservative members to the In-Out referendum will be.

Firstly, there’s a non-trivial possibility that Leave could still win, despite its difficulties at centre-forward. The incentive to “reward” an Outer will be smaller. But if Britain votes to Remain – and if that vote is seen by Conservative members as the result of “dirty tricks” by the Conservative leadership – it could be that many members, far from sticking around for another three to four years to vote in the election, simply decide to leave. The last time that Cameron went against the dearest instincts of many of his party grassroots, the result was victory for the Prime Minister – and an activist base that, as the result of defections to Ukip and cancelled membership fees, is more socially liberal and more sympathetic to Cameron than it was before. Don’t forget that, for all the worry about “entryism” in the Labour leadership, it was “exitism” – of Labour members who supported David Miliband and liked the New Labour years  - that shifted that party towards Jeremy Corbyn.

It could be that if – as Brady predicts in this week’s New Statesman – the final two is an Inner and an Outer, the Eurosceptic candidate finds that the members who might have backed them are simply no longer around.

It comes back to the biggest known unknown in the race to succeed Cameron: Conservative members. For the first time in British political history, a Prime Minister will be chosen, not by MPs with an electoral mandate of their own or by voters at a general election but by an entirelyself-selecting group: party members. And we simply don't know enough about what they feel - yet.
