Fighting Flab

In my last post, I underwent a scientific ramble upon the subject of fat, going into a little of the basic chemistry and biology of the whole business. However, what I did not touch so much on is the giant elephant in the room that surrounds all talk of fat in our modern world, and looks poised to become one of the defining issues of the twenty-first century- that of obesity and overweightness.

I am not, however, about to analyse obesity as a whole in this post, but instead intend to consider why attempting to counteract this, and the slimming industry in general, have become such major bones of contention for so many people. There’s no denying that the slimming industry is worth a veritable fortune- one analyst I saw on TV the other day estimated that a simple cure-all for the world’s obesity problem could be worth up to four trillion dollars, particularly given the boom in public obesity in countries like Brazil and China. However, this doesn’t mean that slimming is popular or that everyone goes in for it- if slimming down weren’t such a problem for so many people, there wouldn’t be an obesity problem worth speaking of, and it’s an open secret that around 99.9% people attempting a new diet fail to keep any weight off in the long term.

To begin, let us consult the very basics. For practical purposes in terms of losing weight, fat is basically energy stored by your body in physical form; the formation of the triglyceride molecules that make up fat requires energy, ‘using up’ any excess energy your body may have, and breaking them apart (the leftover ‘bits’ of the broken-down triglyceride molecules are effectively waste products that are transported to the kidneys via the bloodstream, and are later eliminated from the body in urine) releases this stored energy for your body to use, in order to keep your various bodily functions going and allowing you to move around and do things. Thus, any difference between the amount of energy your body consumes (in food, mainly; a ‘calorie’ is nothing more than an old unit of energy, just like the ‘joule’ unit used in modern science) and uses is offset by your fat reserves- if you put in more than you get out, your fat stores increases, and vice-versa. Thus, the only real challenge facing a slimmer wanting to shed their excess fat is to expend more energy than they consume (leaving to one side for this post various claims that certain foods make you fatter than equivalents of a similar calorific value). Just so we’re all clear on this.

The first concern to raise its ugly head when considering this problem is the simple question of ‘how much energy do we actually expend per day?’. Many people will look to the little table of government-issued Guideline Daily Amounts of various nutrients that you find on the side of most food packaging, but it must be remembered that these are only ‘Guidelines’ after all and a more personal evaluation may be of use. The amount of energy your body uses per day is known as your Metabolic Rate, and a good starting point for an aspiring slimmer would be to calculate your Resting Metabolic Rate (RMR). One’s RMR is a measure of how much energy a person of your gender, age, height and weight would normally (some people may have unusually fast or slow metabolisms, but these people are rare and ‘I have a slow metabolism’ is more often an exuse than reality) expend per day were they utterly at rest; not moving, not doing anything, this is the minimum amount of energy your body needs in order to function. RMR calculators such as this one are freely available online, and that one also features a separate calculator (under ‘Calorie Calculator) that allows you to (very roughly) estimate your total calorie consumption per day. The final number you get out of this latter process is a very useful guideline to the aspiring slimmer.

However, simply aiming to eat less than that number is no guarantee of long-term weight loss. For one thing, many people give up on diets because they can see no immediate results, but this is because ‘burning’ fat is an inherently slow progress. Depending on your source, fat stores between 7500 and 9000 calories per kilogram, meaning that if you are on a diet in which you eat 500 calories less than you expend (and I’m being generous here; a 500 calorie shortfall will leave you feeling very hungry), you can only expect to lose a kilogram of fat every 2-3 weeks. Even this may be  masked if our hypothetical slimmer decides to exercise a bit more too; regular exercise will cause a person to put on muscle (which weighs more than fat) and thus make the loss of weight seem less impressive- but we’ll come onto exercise in a minute.

The other major issue facing those who try to lose weight by dieting is the fact that diets are really, really unpleasant. For one thing, the constant calorie-counting provides unwanted mental strain for many (hence the popularity of points-based diets and similar that do the calculations for you), and this mental fatigue can serve to only exacerbate the gnawing hunger in our empty bellies at the end of a day when we’ve eaten enough calories but not enough to satisfy our stomach. Not only do dieters frequently feel hungry, they also have to deal with a bland diet of lettuce and cottage cheese- and however much we can pretend that we find these delicate things delicious, they don’t quite compare to the stomach-filling satisfaction of a thick, fatty, meaty burger.

The problem is that our hunger is not dictated by how many calories we have consumed, but by how physically full our stomach is, and whilst there are a few tricks that can be used to try and counteract this (a personal favourite is to down a pint of water when feeling peckish, just to give my stomach a large physical amount of stuff to process) none of them really compare to everyone’s dream of being able to eat as much as they like and still not get thin. So, if attempting to limit our intake of energy alone isn’t enough (although diet is most certainly a vital part of keeping our weight down), our only remaining option is to increase the amount of energy we expend, and that means exercise.

The benefits of exercise in relation to weight loss are generally poorly understood by most people; whilst the very act of getting our bodies moving does expend energy, as the little calorie meter on an exercise regime may show, the actual amount of excess energy expended by this process is usually very little; a half-hour run may only expend a cupcake’s worth of energy. No, the real benefits to exercise concern the metabolism; exercise and leading a generally active lifestyle causes your overall metabolic rate to rise, which is why relatively short but regular bouts of exercise (which constantly ‘top up’ one’s metabolic rate) are generally more productive than a four hour long weekend blowout that only boosts the metabolic rate for a small portion of one’s week. This is why the oft-quoted adage instructing people to do 10,000 steps per day has hung around for so long; I honestly believe that were everyone to follow this advice, there would not be a serious obesity problem. Not only that, but as mentioned before exercise, particularly intense exercise such as sprinting or weight training, will build muscle- muscle whose cells will need to be constantly provided with energy in order to stay alive, thus increasing one’s metabolic rate in the long- as well as short-term.

One final pitfall to be noted with attempting to lose weight in this fashion involves attempting to keep it off. It must be borne in mind that people of a lower weight have a lower RMR and thus need less energy, meaning that if a successful dieter reverts to their pre-diet practices they will be eating too much and will just balloon back to the weight they were. Thus, when one makes a commitment to exercise or better eating it has got to be a genuine change in lifestyle (something very few people are willing to commit to) in order to work for the long-term.

That’s one of two reasons why an unpleasant diet of celery sticks probably isn’t a great weight loss solution; the other reason concerns the other benefit of exercise. Someone who regularly exercises isn’t just likely to be slimmer than a similar person who doesn’t, but to be healthier as well- their heart will be healthier, their muscles more able to perform practical real-world tasks, and their body is generally less likely to suffer from the ravages of time and disease. A lot of the stated health problems that come from being overweight or obese are merely symptomatic of people who eat bad food and don’t exercise sufficiently, rather than being directly caused by being overweight. That’s why very few people worry after the cardiovascular health of Jonny Wilkinson, World Cup-winning rugby star and shining light of Toulon RC: a man whose BMI classes him as morbidly obese.

3500 calories per pound

This looks set to be the concluding post in this particular little series on the subject of obesity and overweightness. So, to summarise where we’ve been so far- post 1: that there are a lot of slightly chubby people present in the western world leading to statistics supporting a massive obesity problem, and that even this mediocre degree of fatness can be seriously damaging to your health. Post 2: why we have spent recent history getting slightly chubby. And for today, post 3: how one can try to do your bit, especially following the Christmas excesses and the soon-broken promises of New Year, to lose some of that excess poundage.

It was Albert Einstein who first demonstrated that mass was nothing more than stored energy, and although the theory behind that precise idea doesn’t really correlate with biology the principle still stands; fat is your body’s way of storing energy. It’s also a vital body tissue, and is not a 100% bad and evil thing to ingest, but if you want to lose it then the aim should simply be one of ensuring that one’s energy output, in the form of exercise  exceeds one’s energy input, in the form of food. The body’s response to this is to use up some of its fat stores to replace this lost energy (although this process can take up to a week to run its full course; the body is a complicated thing), meaning that the amount of fat in/on your body will gradually decrease over time. Therefore, slimming down is a process that is best approached from two directions; restricting what’s going in, and increasing what’s going out (both at the same time is infinitely more effective than an either/or process). I’ll deal with what’s going in first.

The most important point to make about improving one’s diet, and when considering weight loss generally, is that there are no cheats. There are no wonder pills that will shed 20lb of body fat in a week, and no super-foods or nutritional supplements that will slim you down in a matter of months. Losing weight is always going to be a messy business that will take several months at a minimum (the title of this post refers to the calorie content of body fat, meaning that to lose one pound you must expend 3500 more calories than you ingest over a given period of time), and unfortunately prevention is better than cure; but moping won’t help anyone, so let’s just gather our resolve and move on.

There is currently a huge debate going on concerning the nation’s diet problems of amount versus content; whether people are eating too much, or just the wrong stuff. In most cases it’s probably going to be a mixture of the two, but I tend to favour the latter answer; and in any case, there’s not much I can say about the former beyond ‘eat less stuff’. I am not a good enough cook to offer any great advice on what foods you should or shouldn’t be avoiding, particularly since the consensus appears to change every fortnight, so instead I will concentrate on the one solid piece of advice that I can champion; cook your own stuff.

This is a piece of advice that many people find hard to cope with- as I said in my last post, our body doesn’t want to waste time cooking when it could be eating. When faced with the unknown product of one’s efforts in an hours time, and the surety of a ready meal or fast food within five minutes, the latter option and all the crap that goes in it starts to seem a lot more attractive. The trick is, therefore, to learn how to cook quickly- the best meals should either take less than 10-15 minutes of actual effort to prepare and make, or be able to be made in large amounts and last for a week or more. Or, even better, both. Skilled chefs achieve this by having their skills honed to a fine art and working at a furious rate, but then again they’re getting paid for it; for the layman, a better solution is to know the right dishes. I’m not going to include a full recipe list, but there are thousands online, and there is a skill to reading recipes; it can get easy to get lost between a long list of numbers and a complicated ordering system, but reading between the lines one can often identify which recipes mean ‘chop it all up and chuck in some water for half an hour’.

That’s a very brief touch on the issue, but now I want to move on and look at energy going out; exercise. I personally would recommend sport, particularly team sport, as the most reliably fun way to get fit and enjoy oneself on a weekend- rugby has always done me right. If you’re looking in the right place, age shouldn’t be an issue (I’ve seen a 50 year old play alongside a 19 year old student at a club rugby match near me), and neither should skill so long as you are willing to give it a decent go; but, sport’s not for everyone and can present injury issues so I’ll also look elsewhere.

The traditional form of fat-burning exercise is jogging, but that’s an idea to be taken with a large pinch of salt and caution. Regular joggers will lose weight it’s true, but jogging places an awful lot of stress on one’s joints (swimming, cycling and rowing are all good forms of ‘low-impact exercise’ that avoid this issue), and suffers the crowning flaw of being boring as hell. To me, anyway- it takes up a good chunk of time, during which one’s mind is so filled with the thump of footfalls and aching limbs that one is forced to endure the experience rather than enjoy it. I’ll put up with that for strength exercises, but not for weight loss when two far better techniques present themselves; intensity sessions and walking.

Intensity sessions is just a posh name for doing very, very tiring exercise for a short period of time; they’re great for burning fat & building fitness, but I’ll warn you now that they are not pleasant. As the name suggest, these involve very high-intensity exercise (as a general rule, you not be able to talk throughout high-intensity work) performed either continuously or next to continuously for relatively short periods of time- an 8 minute session a few times a week should be plenty. This exercise can take many forms; shuttle runs (sprinting back and forth as fast as possible between two marked points or lines), suicides (doing shuttle runs between one ‘base’ line and a number of different lines at different distances from the base, such that one’s runs change in length after each set) and tabata sets (picking an easily repeatable exercise, such as squats, performing them as fast as possible for 20 seconds, followed by 10 seconds of rest, then another 20 seconds of exercise, and so on for 4-8 minute) are just three examples. Effective though these are, it’s difficult to find an area of empty space to perform them without getting awkward looks and the odd spot of abuse from passers-by or neighbours, so they may not be ideal for many people (tabata sets or other exercises such as press ups are an exception, and can generally be done in a bedroom; Mark Lauren’s excellent ‘You Are Your Own Gym’ is a great place to start for anyone interested in pursuing this route to lose weight & build muscle). This leaves us with one more option; walking.

To my mind, if everyone ate properly and walked 10,000 steps per day, the scare stats behind the media’s obesity fix would disappear within a matter of months. 10,000 steps may seem a lot, and for many holding office jobs it may seem impossible, but walking is a wonderful form of exercise since it allows you to lose oneself in thought or music, whichever takes your fancy. Even if you don’t have time for a separate walk, with a pedometer in hand (they are built into many modern iPods, and free pedometer apps are available for both iPhone and Android) and a target in mind (10k is the standard) then after a couple of weeks it’s not unusual to find yourself subtly changing the tiny aspects of your day (stairs instead of lift, that sort of thing) to try and hit your target; and the results will follow. As car ownership, an office economy and lack of free time have all grown in the last few decades, we as a nation do not walk as much as we used to. It’s high time that changed.

Why the chubs?

My last post dealt with the thorny issue of obesity, both it’s increasing presence in our everyday lives, and what for me is the underlying reason behind the stats that back up media scare stories concerning ‘the obesity epidemic’- the rise in size of the ‘average’ person over the last few decades. The precise causes of this trend can be put down to a whole host of societal factors within our modern age, but that story is boring as hell and has been repeated countless times by commenters far more adept in this field than me. Instead, today I wish present the case for modern-day obesity as a problem concerning the fundamental biology of a human being.

We, and our dim and distant ancestors of the scaly/furry variety, have spent the last few million years living wild; hunting, fighting and generally acting much like any other evolutionary pathway. Thus, we can learn a lot about our own inbuilt biology and instincts by studying the behaviour of animals currently alive today, and when we do so, several interesting animal eating habits become apparent. As anyone who has tried it as a child can attest (and I speak from personal experience), grass is not good stuff to eat. It’s tough, it takes a lot of chewing and processing (many herbivores have multiple stomachs to make sure they squeeze the maximum nutritional value out of their food), and there really isn’t much of it to power a fully-functional being. As such, grazers on grass and other such tough plant matter (such as leaves) will spend most of their lives doing nothing but guzzle the stuff, trying to get as much as possible through their system. Other animals will favour food with a higher nutritional content, such as fruits, tubers or, in many cases, meat, but these frequently present issues. Fruits are highly seasonal and rarely available in a large enough volume to support a large population, as well as being quite hard to get a lot of down; plants try to ‘design’ fruits so that each visitor takes only a few at a time, so as best to spread their seeds far and wide, and as such there are few animals that can sustain themselves on such a diet.  Other food such as tubers or nuts are hard to get at, needing to be dug up or broken in highly energy-consuming activities, whilst meat has the annoying habit of running away or fighting back whenever you try to get at it. As anyone who watches nature documentaries will attest, most large predators will only eat once every few days (admittedly rather heavily).

The unifying factor of all of this is that food is, in the wild, highly energy- and time-consuming to get hold of and consume, since every source of it guards its prize jealously. Therefore, any animal that wants to survive in this tough world must be near-constantly in pursuit of food simply to fulfil all of its life functions, and this is characterised by being perpetually hungry. Hunger is a body’s way of telling us that we should get more food, and in the wild this constant desire for more is kept in check by the difficulty that getting hold of it entails. Similarly, animal bodies try to assuage this desire by being lazy; if something isn’t necessary, then there’s no point wasting valuable energy going after it (since this will mean spending more time going after food to replace lost energy.)

However, in recent history (and a spectacularly short period of time from evolution’s point of view), one particular species called homo sapiens came up with this great idea called civilisation, which basically entailed the pooling and sharing of skill and resources in order to best benefit everyone as a whole. As an evolutionary success story, this is right up there with developing multicellular body structures in terms of being awesome, and it has enabled us humans to live far more comfortable lives than our ancestors did, with correspondingly far greater access to food. This has proved particularly true over the last two centuries, as technological advances in a more democratic society have improved the everyman’s access to food and comfortable living to a truly astounding degree. Unfortunately (from the point of view of our waistline) the instincts of our bodies haven’t quite caught up to the idea that when we want/need food, we can just get food, without all that inconvenient running around after it to get in the way. Not only that, but a lack of pack hierarchy combined with this increased availability means that we can stock up on food until we have eaten our absolute fill if so we wish; the difference between ‘satiated’ and ‘stuffed’ can work out as well over 1000 calories per meal, and over a long period of time it only takes a little more than we should be having every day to start packing on the pounds. Combine that with our natural predilection to laziness meaning that we don’t naturally think of going out for some exercise as fun purely for its own sake, and the fact that we no longer burn calories chasing our food, or in the muscles we build up from said chasing, and we find ourselves consuming a lot more calories than we really should be.

Not only that, but during this time we have also got into the habit of spending a lot of time worrying over the taste and texture of our food. This means that, unlike our ancestors who were just fine with simply jumping on a squirrel and devouring the thing, we have to go through the whole rigmarole of getting stuff out of the fridge, spending two hours slaving away in a kitchen and attempting to cook something vaguely resembling tasty. This wait is not something out bodies enjoy very much, meaning we often turn to ‘quick fixes’ when in need of food; stuff like bread, pasta or ready meals. Whilst we all know how much crap goes into ready meals (which should, as a rule, never be bought by anyone who cares even in the slightest about their health; salt content of those things is insane) and other such ‘quick fixes’, fewer people are aware of the impact a high intake of whole grains can have on our bodies. Stuff like bread and rice only started being eaten by humans a few thousand years ago, as we discovered the benefits of farming and cooking, and whilst they are undoubtedly a good food source (and are very, very difficult to cut from one’s diet whilst still remaining healthy) our bodies have simply not had enough time, evolutionarily speaking, to get used to them. This means they have a tendency to not make us feel as full as their calorie content should suggest, thus meaning that we eat more than our body in fact needs (if you want to feel full whilst not taking in so many calories, protein is the way to go; meat, fish and dairy are great for this).

This is all rather academic, but what does it mean for you if you want to lose a bit of weight? I am no expert on this, but then again neither are most of the people acting as self-proclaimed nutritionists in the general media, and anyway, I don’t have any better ideas for posts. So, look at my next post for my, admittedly basic, advice for anyone trying to make themselves that little bit healthier, especially if you’re trying to work of a few of the pounds built up over this festive season.

The Slightly Chubby Brigade

As the news will tell you at every single available opportunity, we are living through an obesity crisis. Across the western world (USA being the worst and Britain coming in second) our average national BMI is increasing and the number of obese and overweight people, and children especially, looks to be soaring across the board. Only the other day I saw a statistic that said nearly a third of children are now leaving primary school (ie one third of eleven year-olds) overweight, and such solemn numbers frequently make headlines.

This is a huge issue, encompassing several different issues and topics that I will attempt to consider over my next few posts (yeah, ‘nother multi-parter coming up), but for many of us it seems hideously exaggerated. I mean yes, we’ve all seen the kind of super-flabby people, the kind the news footage always cuts to when we hear some obesity health scare, the kind who are wider than they are tall and need a mobility scooter just to get around most of the time. We look at these pictures and we tut, and we might consider our own shape- but we’re basically fine, aren’t we. Sure, there’s a bit of a belly showing, but that’s normal- a good energy store and piece of insulation, in fact, and we would like to have a life beyond the weight-obsessed calorie counters that hardcore slimmers all seem to be. We don’t need to worry, do we?

Well, according to the numbers, actually we do. The average height of a Briton… actually, if you’re stumbling across this at home and you consider yourself normal, go and weigh yourself and, if you can, measure your height as well. Write those numbers down, and now continue reading. The average height of a Briton at the moment is 1.75m, or around 5’9″ in old money, and we might consider a normal weight for that height to be around 80 kilos, or 170 pounds. That might seem normal enough; a bit of a paunch, but able to get around and walk, and certainly no one would call you fat. Except perhaps your doctor, because according to the BMI chart I’ve got pulled up a 5 foot 9, 80 kilo human is deemed clinically overweight. Not by much, but you’d still weigh more than is healthy- in fact, one stat I heard a while ago puts the average Briton at this BMI. Try it with your measurements; BMI charts are freely available over the web.

This, to me, is one of the real underlying causes of ‘the obesity epidemic’- a fundamental misunderstanding of what ‘overweight’ consists of. Whenever our hideously awful everyone-dead-from-McDonalds-overdose etc. etc. diet is brought up on the news, it is always annotated by pictures of hanging bellies and bouncing flab, the kind of bodies that make one almost physically sick to look at. But, whilst these people certainly exist, there are not enough of them for the obesity issue to be even worth mentioning in everyday society; whilst the proportion of morbidly obese people is significant, it’s not seriously worth thought for most of us.

No, the real cause for all the chilling statistics we hear on the news is all the people who don’t look to be overweight. The kind whose diet isn’t appalling (no 24/7 McDonaldses), who are quite capable of exercise when it suits them, and who might take a rough glance at the dietary information of the stuff they buy in the supermarket. But these people are nonetheless hovering on the overweight borderline, pulling up the national average, despite the fact that they don’t consider anything to be wrong; in fact, some women who are according to the evil numbers overweight, may consider it almost dutiful to not become obsessed over shedding every pound and to maintain their curves. Having a bit of excess weight is, after all, still better than being underweight and anorexic, and the body image pressures some young women are coming under are just as much of an issue as national obesity. Even for those who don’t have such opinions, many of the slightly overweight feel that they don’t have any weight issues and that there’s surely no significant health risk associated with a ‘bit of meat on your bones’ (it’s actually muscle, rather than fat, that technically forms meat, but ho hum); as such, they have absolutely no motivation to get their weight down, as they don’t think they need to.

I won’t waste much of my time on all the reasons for this statement, but unfortunately even this slight degree of overweight-ness will significantly increase your risk of major health problems somewhere down the line, particularly that of heart disease (which is going through the roof at the moment); diabetes isn’t likely to be a risk for the overweight unless they’re really overdoing things, but that’s also a potential, and very serious, health hazard. The trouble is that many of us find it hard to make this connection if we basically feel healthy. Despite what the doctor says and no matter how much we trust them, if we are capable of going for a nice walk and generally getting about without getting out of breath or feeling bad then we probably feel justified in thinking of ourselves as healthy. Our heart doesn’t seem about to give out, so why worry about it.

The thing to remember is that the heart is just a muscle, so if it isn’t stressed it will degrade just like any other. You know those triceps that haven’t done a press up in five years? Feel how small and weak they are? Yeah, that kind of thing can quite easily happen to the muscles that are responsible for keeping you alive. Your heart might be pumping all day long and be a different type of muscle, so the process will be slower, but give it twenty years and you might start to see the effects.

But anyway, I’m not here to lecture you about your health; that’s far too depressing and dull for my liking- the only point I was trying to make is that many of the accidental contributors to ‘the obesity epidemic’ are probably unaware that their health is in any way a problem, and not really through fault of their own. So whose fault is it then? Well, that one can wait until next time…

Why we made the bid in the first place

…and now we arrive at the slack time, that couple of weeks between the end of the Olympics and start of the Paralympics where everyone gets a chance to relax, wind down a little, and take time away from being as resolutely enthusiastic and patriotic as we have been required to for the last two weeks (or a lot longer if you factor in the Royal Wedding and Queen’s Jubilee). However, it’s also an undoubtedly good time to reflect on what have been, whatever your viewpoint, a very eventful last couple of weeks.

To my mind, and certainly to those of the Olympic organisers, these games have been a success. Whether you feel that it was all a colossal waste of money (although how anyone can think that of an event featuring the Queen parachuting out of a helicopter alongside James Bond is somewhat puzzling to me), or the single most amazing thing to grace the earth this side of its existence (in which case you could probably do with a nice lie down at the very least), its motto has been to ‘Inspire a Generation’. From a purely numerical perspective, it appears to have worked- sports clubs of all sorts up and down the land, even in niche areas such as handball, have been inundated with requests from enthusiastic youngsters after membership, and every other sentence among BBC pundits at the moment appears to include the phrase ‘the next Mo Farah/Usain Bolt/Ben Ainslie/Chris Hoy’ (delete as applicable).

However, I think that in this respect they are missing the point slightly, but to explain what I mean I’m going to have to go on a bit of a tangent. Trust me, it’ll make sense by the end.

So…, what is the point of sport? This has always been a tricky one to answer, the kind of question posed by the kind of awkward people who are likely to soon find an answer flying swiftly towards them in foot-shaped form. In fact, I have yet to hear a convincing argument as to exactly why we watch sport, apart from that it is for some unexplained reason compelling to do so. But even if we stick to the act of participation, why do we bother?

Academics and non-sportspeople have always had a whole host of reasons why not, ever since the days that they were the skinny, speccy one last to be picked in the dreaded playground football lineup (I’ve been there- not fun). Humans are naturally lazy (an evolutionary side-effect of using our brains rather than brawn to get ahead), and the idea of running around a wet, muddy field expending a lot of precious energy for no immediately obvious reason is obviously unappealing. Then we consider that the gain of sport, the extent to which it contributes to making the world a better place is, in material terms at least, apparently quite small. Humankind’s sporting endeavours use up a lot of material for equipment, burn a lot of precious calories that could be used elsewhere around the world to help the starving, and often demand truly vast expenses in terms of facilities and, in the professional world, salaries. Even this economic consideration does not take into account the loss in income presented by the using up of acres upon acres of valuable land for sports facilities and pitches. Sport also increases the danger factor of our lives, with a heavy risk of injury ranging from minor knocks to severe, debilitating disabilities (such as spinal injury), all of which only adds to the strain on health services worldwide and further increases the ‘cost’ of sport to the world.

So why do we bother with it at all? Why is it that the question governments are asking themselves is “why aren’t enough kids playing sport?” rather than ‘why are so many of them doing so’? Simple reason is that, from every analytical perspective, the benefits of sport far outweigh the costs. 10% of the NHS’ entire budget is spent on dealing with diabetes, just one of a host of health problems associated with obesity, and if just half of these cases were to disappear thanks to a healthier lifestyle it would free up around an extra £5 billion- by 2035, diabetes could be costing the country around £17 billion unless something changes. Then there are the physical benefits of sport, the stuff it enables us to do. In the modern world being able to run a kilometre and a half in four minutes might seem like a pointless skill, but when you’re being chased down the street by a potential mugger (bad example I know, but it’ll do) then you’d definitely rather be a fit, athletic runner than slow, lumbering and overweight. Sport is also one of the largest commercial industries on earth, if not on a professional level then at least in terms of manufacture and sale of equipment and such, worth billions worldwide each year and providing many thousands or even millions of jobs (although some of the manufacturing does admittedly have a dubious human rights record). The health benefits of sport go far beyond the physical & economic too, as both the endorphins released during physical activity and the benefits of a healthy lifestyle are known to increase happiness & general well-being, surely the ultimate goals of all our lives. But perhaps most valuable of all is the social side of sport. Whilst some sports (or, more specifically, some of the &%^$£*)@s involved) have a reputation for being exclusive and for demoralising hopeful youngsters, sport when done properly is a powerful force for social interaction & making friends, as well as being a great social equaliser. As old Etonian, heir his father’s baronet and Olympic 110m hurdles finalist Lawrence Clarke recently pointed out in an interview ‘On the track it doesn’t matter how rich your family is or where you’ve come from or where you went to school; all that matters is how fast you can get to the finish line’ (I’m paraphrasing, but that was the general gist). Over the years, sport has allowed mixing between people of a myriad of different genders and nationalities, allowing messages of goodwill to spread between them and changing the world’s social and political landscape immeasurably. This Olympics was, for example, the first in which Palestinian and Saudi Arabian women competed, potentially paving the way for increased gender equality in these two countries.

Clearly, when we all get behind it, sport has the power to be an immense tool for good. But notice that nowhere in that argument was any mention made of being the physical best, being on top of the world, breaking world records because, try as one might, the value of such achievement is solely that of entertainment and the odd moment of inspiration. Valuable though those two things surely are, they cannot begin to compare with the incalculable benefits of a population, a country, a world united by sport for the good of us all. So, in many respects, the success of an Olympic games should not be judged by whether it inspires a new superstar, but rather by how it encourages the guy who turns up with him at that first training session, who might never be that good a competitor… but who carries on turning up anyway. The aim of top-flight sport should not be to inspire the best. It should simply be to inspire the average.
