What’s wrong with the New Year Detox? Well, pretty much everything.

Posted on

It’s coming to the end of the Dead Zone, those few structureless days between Christmas and New Year’s where there are no rules. Nobody knows what day it is or what to do (is it still okay to eat mince pies?) We’re off work but there’s nowhere to go because we’re all broke from festive fiscal excess. And that’s not the only extravagance we are left to contemplate. Three solid weeks of unabashed eating, drinking and being merry have left most of us with a little more abdominal insulation than seems fair – we were having such a good time. Now we have a few long days to rub our bellies in forlorn resignation, lamenting our gustatory largesse and making heartfelt, if vague, promises to put it right on the first Monday in January. So, it’s less of a ‘Dead Zone’ and more a kind of alimentary purgatory where the already devoured sins are weighed up against the promises to repent.

 Repentance comes in the most puritanical of forms, the January Detox, a month of mass mania and ritual self-flagellation. Bodies are pounded on pavements and vile-tasting shots of medicinal herbs are downed in order for the body to be cleansed. This annual penance for the sins of December results in maybe a few pounds temporarily lost but comes at the cost of a month of your life spent in constant self-loathing, misery and deprivation. This is clearly no way to live but it has become a Hunger Game that we play with ourselves, goaded on by the innumerable media outlets and self-styled gurus looking to cash in on this most harmful annual custom. And it certainly is harmful, both physically and psychologically, and it’s about time that we stopped.

 There are so many fundamental problems with the January Detox that, like a chocolate orange, it is better to break it down into chunks.

 The Science Problem

 The first of many problems with the January Detox is the one that is the easiest to expose: it has absolutely no scientific basis. Unless you are addicted to heroin or have been licking lead pipes and require medical intervention detoxing is not a thing. Year after year doctors and science writers valiantly debunk the myth that your body needs the assistance of juices, gels, patches, enemas, orcelebrity endorsed magic water to eliminate waste products. They say things like this:

 “Let’s be clear,” says Edzard Ernst, emeritus professor of complementary medicine at Exeter University, “there are two types of detox: one is respectable and the other isn’t.” The respectable one, he says, is the medical treatment of people with life-threatening drug addictions. “The other is the word being hijacked by entrepreneurs, quacks and charlatans to sell a bogus treatment that allegedly detoxifies your body of toxins you’re supposed to have accumulated.”– The Guardian, December 2014 (1)

 They present reviews of the available literature and conclude: “To the best of our knowledge, no randomised controlled trials have been conducted to assess the effectiveness of commercial detox diets in humans.” (2) That is to say that there is no good quality evidence that any of this stuff works. Or just ‘no evidence’.

We are reminded that no two manufacturers of detox products or purveyors of detox diets can agree on what a toxin is but we blithely trundle on in the pursuit of purity presumably because the idea of a ‘detox’ performs a wholly different function to the reality of it. I’ll get to that in a bit.

As with many other illusions that we like to keep hold of in the face of objective scrutiny (and we all do at times) the wealth of contradictory evidence is casually dismissed in favour of specious subjective experience. During the annual purge detoxers report experiencing symptoms such as bodily aches, brain fog, cravings, acne, poor sleep and digestive problems all of which are referenced on health and weight loss websites as being signs that you are detoxifying (hoorah!). All of which can be more credibly attributed to inadequate caloric intake and a sudden change in diet (oh, wait…).

But, no big deal, right? So maybe it doesn’t technically do anything, there’s no harm done and maybe it will kick-start some healthy changes, yeah? Um..no.

 The Sustainability Problem

 This is where it gets a bit technical (*dusts off A-level biology textbook*). The reason that diets of this kind are indicated for short periods of time is because they are inherently unsustainable. When you drastically reduce your caloric intake below basal metabolic rate (the amount needed to keep the organ systems ticking over) it doesn’t take long for the body to glean that there is something drastically wrong. After about 2-3 days the body’s glycogen (sugar) stores are depleted and metabolism switches to using fat as fuel and the production of ketones that the brain can use for energy. There is still, though, a small sugar requirement. In the absence of dietary carbohydrates these missing sugars are synthesised from the body’s own proteins. The body will begin to break down lean tissue (muscle and organs) because ‘the first priority of metabolism in starvation is to provide sufficient glucose to the brain…Initial sources of protein are those that turn over rapidly, such as proteins of the intestinal epithelium. (3) It is worth knowing then that the cells that line the intestine create a barrier between the contents of the gut (including pathogens) and the rest of the body. Damage to this lining impairs the immune system and exacerbates digestive disorders such as IBS[KW1]  and Ulcerative Colitis (4). In the long term very low calorie diets can cause serious damage to the organs and this is the reason that Anorexia Nervosa is the most deadly psychiatric condition, with death often caused by heart or kidney failure.

Of course I’m not talking here about chronic psychiatric conditions. A detox is only a month, maybe six weeks so the risks of long term damage are low. Except they’re not. A study published in 2011 (5) looked at the long-term effects of short term ‘very-low-energy’ (500-550 calories per day) diets. A year after completing the 8 week diet:

  • Levels of leptin, the hormone responsible for feelings of satiety, were significantly lower than at the start of the study

  • Levels of ghrelin, the ‘hunger hormone’ were significantly higher

  • Peptide YY, an appetite suppressor, was lower

  • Self-reported ratings of hunger, desire for food and urge to eat were higher as were preoccupations with food thoughts

  • Participants expended less energy and felt less full.

So brief exposure to a very low calorie diet resulted in long-term hormonal changes that left the dieters hungrier and more obsessed with food than they had been at the start, increased the likelihood of subsequent weight gain and made it harder to lose the next time. The particular cruelty of this situation is that dieters who regain weight (and 90% of all dieters do) will believe – or worse, be told – that it was their lack of control or the failure of their willpower that is to blame not the powerful biological adaptations to starvation that were set in motion by the diet/detox in the first place. It is a pernicious lie and it makes me angry. Throw the sense of total failure in to the pot with the misery of feeling hungry and deprived the whole time and the fact that this is no long-term solution becomes self-evident.

The irony is that not only does the body resist restriction but the brain does too. In a paper published in 1975(6) restrained eaters – people who tried to rigidly control what they ate and avoided unhealthy foods – tended to overeat when their guard was down. Unrestrained/relaxed eaters ate to their appetites; they stopped when they were full. Making a food forbidden makes us much more likely to overeat when the opportunity arises.

The Psychological Problems

Perhaps longer lasting than the physical effects are those on the mind and these are the ones that I encounter most frequently, in my consulting room. They are multitudinous but I’ll just hit up the main ones.

The social norms around detoxing – its associations with health, celebrity and ‘instaglamour’ – help to cement the denial and perpetuate the essential illusion: that you are doing something healthy for benevolent reasons. In truth you are not ‘detoxing’ you are ‘crash dieting’. It is not because you want to feel good but because you feel guilty and angry with yourself for overindulging during the festive season. It is a kind of open conspiracy; we all know that ‘detox’ is a code word for ‘crash diet’ but we all nod in silent permissiveness of what could more honestly be called ‘elective starvation’. Somehow the word ‘detox’ seems to soften the edges of extreme dieting. If at any other time of the year (except perhaps before a summer holiday) a friend told you that they were restricting themselves to 450 calories per day you’d worry, think these were desperate measures, tell them it was a bad idea, but in January it’s all good, you wish them well and make a date for drinks in a month’s time. In many ways I would be happier for people to call it what it really is, at least that would be honest. It would be real. And we could address it. As it is ‘detoxing’, ‘cleansing’ and elimination diets are a too often a socially sanctioned cover for disordered eating and eating disorders as is attested by the number of high-profile healthy food bloggers who have admitted to having severe eating disorders (7) and those who haven’t…

Also problematic is that this cycle of binging in December and purging in January (sounding disordered yet?) promotes polarised thinking and behaviour. In CBT this is referred to as ‘all or nothing’ or ‘black and white’ thinking, in psychoanalytic theory it’s known as splitting; the setting up of dichotomous states of mind with no room for moderation or shades of grey. It’s absolute triumph vs total worthlessness, virtue vs sin. It’s the two biscuits that ‘ruin everything’ or the additional pound on the scales that means it is going to be a ‘bad day’. Whilst different therapies use different terms for this phenomenon all are agreed that these kinds of extremes are unhealthy. These harsh attitudes make it impossible to experience self-compassion, a trait that is associated with positive mental health outcomes. People who are self-compassionate are happier, more optimistic and emotionally resilient and less likely to be depressed or anxious (8). Self-compassion isn’t about self-pity or lack of discipline and, interesting, it can support attempts to eat healthily. A recent study suggests that rigid diets tend to result in overeating and that self-compassion can reduce this tendency.(9)

Another facet of this particular brand of splitting is that detoxes tend to be predicated on the consumption of foods that either don’t taste good (I’m looking at you, wheatgrass) or don’t taste of anything (two words: Rice. Cakes) strengthening the association between ‘pain and piety’ and pleasure as ‘sin’. Coming, as it does, so soon after the dietary abandon of December the implication is that eating for pleasure is a bad thing and that one should suffer for health. This is both utterly wrong and incredibly unhelpful, particularly when trying to encourage individuals to eat more healthfully in our currently failing attempts to stem the tsunami of obesity.

Rather than helping dieters to understand their personal relationships with food – including the attitudes to food, weight and body shape in their families, schools, society etc. – the January Detox reinforces the two-headed dietary monster of the ‘one-size-fits-all’ and the ‘quick fix’. It should be common sense that genetically (including the gut microbiome) unique individuals with different food histories would benefit from personalised dietary approaches, and that your relationship with your own body is a life-long partnership requiring ongoing investment. But it’s not and that’s because the diet industry, media outlets and some lifestyle bloggers (a few well-intentioned, others not so much (10)) continue to perpetuate the myth that if you just try hard enough with this short-term intervention everything will be perfect. This is oversimplification to the point of ridiculousness and aspiration to the point of sadism.

Psychologically speaking health lies elsewhere. Somewhere between nutritionism (just nutrients on a plate) and hedonism (I think I ate the plate) is a place where food choices are a result of self-respect, self-awareness and self-compassion. Not aggression, external rules or desperation. For many of us it is not an easy place to get to; there are many outlets competing over the right to tell you what to eat and how you should feel about yourself and it’s been happening for a long time. I sit with patients who were put on diets in infancy because their mothers didn’t want a ‘fat baby’ or whose fathers mocked their adolescent body shape. These children then went in to competitive school environments where the aesthetic was king. Somewhere in the midst of these interpersonal challenges the media intervenes to let us know what the standard is and just how far short of it we are all falling. It can be an enormous task to clear through the layers of extraneous commandments and the years of social training to get back to a place of trust in one’s own body. Anyone who has fed a young child will have a sense of this. A spoonful of food can be mid-flight to the mouth when the child stops. No, I’m done. There might be pathetic half of a fish finger on the plate and, unless they are encouraged to ‘clear the plate’, it will remain abandoned because s/he knows that they don’t need it and what the body doesn’t need it doesn’t want. Children trust their bodies because they haven’t yet be taught not to. Sadly this state doesn’t last long and for many adults the external noise is so powerfully intrusive that the assistance of a therapist is essential in helping to create the quiet and the confidence to hear themselves again.

For a lot of those embarking on it the January Detox has nothing to do with food. Instead it symbolises a different kind of panic; not about the waistline but about the timeline. The closing of another year and the start of a new one inevitably evokes reflection on how the time was spent and, unconsciously for some, how much we might have left. If in this retrospection we feel we have not done enough, not succeeded enough, we can feel a need for a quick win. We cannot change our careers/improve our relationships/get out of debt in a month but we can lose a stone! Drastically changing the body becomes a substitute for feeling powerless to change other areas of our lives. But whilst our energy is focused on just making it through this juice fast the real existential challenges remain unchanged and neglected. It’s that reality issue again.

Being aware of what we are eating and, crucially, why is the key to regaining a compassionate relationship with the body and a non-anxious attitude to food and eating. Being mindful of what we are really hungry for (food, comfort, sleep, affection) enables us to make more honest food and life choices. If we ate mindfully throughout the year, including allowing room for the occasional overeating, we would negate the need for radical ‘cleansing’ in January.

The January Detox encapsulates everything that is wrong with the way we think about our bodies, food and eating. It is no way to live and no way to treat someone as important as you.

A big thank you to everyone who came to our first supper club, Memory and Nostalgia. Kimberley and I were just so pleased with the evening. We sold out, almost every plate came back empty and we got some great feedback from our survey – in fact everyone who

We’ve got a load of new events coming in 2016. The first of which is Kimberley’s talk How you Forgot to Eat: The Challenge of Feeding Yourself”, which is being held on January 14. Early bird tickets are available now, so hurry!

Thanks again to all of our supporters and we wish you all a joyful festive season and the most enjoyable new year.

Thoughtful about food

Posted on Updated on

Cookery programmes, food blogs, food porn – we are increasingly food obsessed. In fact, we have more options and opportunities to eat than ever before.

Sure, we eat when we are hungry but physical hunger is only one part of the story. We each have a deeply personal relationship with food that is driven by the social, cultural, and individual meanings associated with it. Food opens the door to memory and emotion, but so often in our lives, food becomes meaningless, just a functional ‘fuel’ or a disposable commodity.

We want to get you back in touch with food. Through a series of events and talks we’ll invite you to explore what food means to you, not just how it tastes, but how it makes you feel
