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.

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…

Aging

OK, I know it was a while ago, but who watched Felix Baumgartner’s jump? If you haven’t seen it, then you seriously missed out; the sheer spectacle of the occasion was truly amazing, so unlike anything you’ve ever seen before. We’re fairly used to seeing skydives from aeroplanes, but usually we only see either a long distance shot, jumper’s-eye-view, or a view from the plane showing them being whisked away half a second after jumping. Baumgartner’s feat was… something else, the two images available for the actual jump being direct, static views of a totally vertical fall. Plus, they were so angled to give a sense of the awesome scope of the occasion; one showed directly down to earth below, showing the swirling clouds and the shape of the land, whilst the other shot gave a beautiful demonstration of the earth’s curvature. The height he was at made the whole thing particularly striking; shots from the International Space Station and the moon have showed the earth from further away, but Baumgartner’s unique height made everything seem big enough to be real, yet small enough to be terrifying. And then there was the drop itself; a gentle lean forward from the Austrian, followed by what can only be described as a plummet. You could visibly see the lack of air resistance, so fast was he accelerating compared to our other images of skydivers. The whole business was awe-inspiring. Felix Baumgartner, you sir have some serious balls.

However, I bring this story up not because of the event itself, nor the insane amount of media coverage it received, nor even the internet’s typically entertaining reaction to the whole business (this was probably my favourite). No, the thing that really caught my eye was a little something about Baumgartner himself; namely, that the man who holds the world records for highest freefall, highest manned balloon flight, fastest unassisted speed and second longest freefall ever will be forty-four years old in April.

At his age, he would be ineligible for entry into the British Armed Forces, is closer to collecting his pension than university, and has already experienced more than half his total expected time on this earth. Most men his age are in the process of settling down, finding their place in some management company and getting slightly less annoyed at being passed over for promotion by some youngster with a degree and four boatloads of hopelessly naive enthusiasm. They’re in the line for learning how to relax, taking up golf, being put onto diet plans by their wives and going to improving exhibitions of obscure artists. They are generally not throwing themselves out of balloons 39 kilometres above the surface of the earth, even if they were fit and mobile enough to get inside the capsule with half a gigatonne of sensors and pressure suit (I may be exaggerating slightly).

Baumgartner’s feats for a man of his age (he was also the first man to skydive across the English channel, and holds a hotly disputed record for lowest BASE jump ever) are not rare ones without reason. Human beings are, by their very nature, lazy (more on that another time) and tend to favour the simple, homely life rather one that demands such a high-octane, highly stressful thrill ride of a life experience. This tendency towards laziness also makes us grow naturally more and more unfit as time goes by, our bodies slowly using the ability our boundlessly enthusiastic childish bodies had for scampering up trees and chasing one another, making such seriously impressive physical achievements rare.

And then there’s the activity itself; skydiving, and even more so BASE jumping, is also a dangerous, injury-prone sport, and as such it is rare to find regular practitioners of Baumgartner’s age and experience who have not suffered some kind of reality-checking accident leaving them either injured, scared or, in some cases, dead. Finally, we must consider the fact that there are very few people rich enough and brave enough to give such an expensive, exhilarating hobby as skydiving a serious go, and even less with both the clout, nous, ambition and ability to get a project such as Red Bull Stratos off the ground. And we must also remember that one has to overcome the claustrophobic, restrictive experience of doing the jump in a heavy pressure suit; even Baumgartner had to get help from a sports psychologist to get over his claustrophobia caused by being in the suit.

But then again, maybe we shouldn’t be too surprised. Red Bull Stratos was a culmination of years of effort in a single minded pursuit of a goal, and that required a level of experience in both skydiving and life in general that simply couldn’t be achieved by anyone younger than middle age- the majority of younger, perhaps even more ambitious, skydivers simply could not have got the whole thing done. And we might think that the majority of middle-aged people don’t achieve great things, but then again in the grand scheme of things the majority of everyone don’t end up getting most of the developed world watching them of an evening. Admittedly, the majority of those who do end up doing the most extraordinary physical things are under 35, but there’s always room for an exceptional human to change that archetype. And anyway; look at the list of Nobel Prize winners and certified geniuses on our earth, our leaders and heroes. Many of them have turned their middle age into something truly amazing, and if their field happens to be quantum entanglement rather than BASE jumping then so be it; they can still be extraordinary people.

I don’t really know what the point of this post was, or exactly what conclusion I was trying to draw from it; it basically started off because I thought Felix Baumgartner was a pretty awesome guy, and I happened to notice he was older than I thought he would be. So I suppose it would be best to leave you with a fact and a quote from his jump. Fact: When he jumped, his heart rate was measured as being lower than the average resting (ie lying down doing nothing and not wetting yourself in pants-shitting terror) heart rate of a normal human, so clearly the guy is cool and relaxed to a degree beyond human imagining. Quote: “Sometimes you have to be really high to see how small you really are”.
