Obesity 50 years ago when the medical advice was to cut the carbs

For Obesity Day I thought I’d quote the advice Gary Taubes describes as treatment for obesity in the 1950s.

So seven prominent British clinicians, led by Raymond Greene, published The Practise of Endocrinology in 1951:

Foods to be avoided

  1. Bread and everything else made with flour
  2. Cereals, including breakfast cereals and milk puddings
  3. Potatoes and all other white root vegetables
  4. Food containing much sugar
  5. All sweets

Foods to be embraced

  1. Meat, fish and birds
  2. All green vegetables
  3. Eggs, dried or fresh (do dried eggs even exist anymore?)
  4. Cheese
  5. Fruit if unsweetened or sweetened with saccharin, except bananas and grapes.

In 1940 a monograph on 50 obese patients found that 41 of them had a “more or less marked preference for starchy and sweet foods; only one patient claimed preference for fatty foods” these patients included “an extremely obese launderers [who had] a craving for laundry starch which she used to eat by the handful, as much as a pound a day…”

When you make the low fat version of food you can do so by adding starch, e.g. Morrison low fat Crème Fraîche has tapioca starch added.

Or in the 1960s textbook on Human Nutrition and Dietetics Sir Stanley Davidson and Reginald Passmore wrote “In great Britain obesity is probably more common among poor women than among the rich [today it definitely is] perhaps because food rich in fat and protein which satisfy appetite more readily than carbohydrate are more expensive than the starchy foods which provide the bulk of cheap meals”. And “All popular ‘slimming regimes’ involve a restriction in dietary carbohydrate”. “The intake of foods rich in carbohydrate should be drastically reduced since overindulgence in such foods is the most common cause of obesity”

50 million copies of Dr Spock’s book said “Rich desserts , the amount of plain, starchy foods (cereals, bread, potatoes) taken is what determines, in the case of most people, how much [weight] they gain or lose”.

And look at Ancel Keys’ observation of the people of Naples eating the Mediterranean diet (though it was the Cretans that were the long lived ones), he describes the small amount of lean meat and the pasta based dishes (a poor region, made even poorer by the war) “The women were fat”. (Ancel Keys was one of the key scientists arguing that saturated fat caused heart disease).

So a low carb high fat (higher fat than we eat now) was fairly standard diet advice in the 1960s. Since then the idea that fat is bad is because saturated fat was bad, and because there was some evidence that diets extremely low in fat  produced really good results in terms of weight loss, for patients coming off junk food  diets (but we’re talking less than 10% fat with no word on whether those are the only good diets). Those diets were studied by Pritikin and they were what inspired George McGovern when he recommended around a 30% fat diet in the Dietary Goals for the United Stats. 30% fat is the current UK recommendation, though the US has now taken the fat limit off.

You can see some of the confusion here by comparing the UK, the Harvard and the Swiss food plates or pyramids.

2016_uk_eatwellguide harvard-pyramid-jan2015-1024x808 harvard-food-pyramid-1024x950swiss-food-pyramid_2011

The UK Eatwell Guide is 1/3 carbs and, whatever they say about wholewheat, the pictures are all of highly refined carbohydrates, while in the Harvard food plate whole grains (no processed refined carbs) are 1/4 of the plate. In the Harvard pyramid cheese is in the second smallest category, but in Switzerland it’s one rank down in the middle of the pyramid (quite amusing). Both Harvard and Switzerland pyramids allow more oil than the UK and they disagree about how much.

The thing that strikes, me looking at my friends lunch, is how many of them consist of even more than 1/3 carbohydrate. A sandwich is probably around 2/3 bread (carbs) vs filling, or call it half. Then add a bag of crisps, 50% of the calories are carbs, (more than 50% of the weight that’s not water). Then throw in a banana, again as a % of calories thats 92% carbohydrate. E voila, you’re eating way more carbs than are recommended by the UK, and even that is probably too much.

The other thing that really struck me was reading Weston Prices’s description of diets around the world.
I want to go into this properly in another post, but briefly, he was a dentist who, in the 1930s, did a tour of the worlds teeth comparing ‘native’ diets of people not in contact with Western civilisation, with the teeth of the same ‘tribe’ of people who were. This includes the Swiss comparing a distant valley, Loetschental, with the lowlands, St Gallen, and the Western Isle in Scotland comparing the side of the island with a port and shop with the other side of the island, as well as the Inuit, Native Americans, Aborigines, etc. etc. etc. In every case the ‘native’ diet produced wonderful straight, healthy teeth while the Western diet didn’t. Indeed we’re talking, all your teeth rotting out of your head by the time you’re 20 (and my Swiss grandmother only had four teeth). In every case the major feature of the Western diet was white flour and sugar. These people were eating an utterly terrible diet by any standard (no wonder TB was so rampant in the olden days). Western Price’s main idea was that these people weren’t getting the fat soluble vitamins, A, D and K2 needed for healthy teeth. Also they weren’t getting any other vitamins either (but when he gave them a small amount of top quality butter their teeth got better so it seems it is the A, D, and K2 for teeth).

So this is a second argument to reduce easily digested white carbohydrates, that used to be known as uniquely fattening. They are entirely empty calories. If we are sedentary and living in heated homes, we don’t need to eat so many calories, which means the food we do eat needs to be better quality to get enough vitamins, minerals, fibre etc.

The final thing, that I’ll try to mention even more briefly before the blog post: What if vitamins A, D and K2 (which need to work together, no point only getting one or two) are so essential for calcium metabolism (as well as teeth) that if we don’t have enough vitamins we have calcium filling up our arteries and becoming atherosclerotic plaques (Atul Gawande described such arteries as being brittle to the touch when he operated on them). What if all of our heart disease is vitamin deficiency? This deserves it’s own blog post. But what if a trivitamin pill could help enormously and saturated fat had nothing to do with it?

So for world obesity day, and to save the NHS, make an effort to swap out your bread, pasta, potatos, polished rice and crisps for vegetables, an egg and a bit of cheese.


How to decide a moral dilemma

I was at a Gresham Lecture yesterday, To Die or not to Die (whether ’tis nobler in the mind to suffer the slung arrows of outrageous fortune, or to take arms against a sea of troubles…). The speaker was Sir Allan Ward a judge with a 60 year career behind him who is now retired with time to give interesting talks.

He started by saying how awful the death penalty is and described two of the prisoners he had met in South Africa who had completely crumpled and been destroyed just by the sentence, even before the actual execution. This was moving, but also, in the UK, safely dated, we have gotten rid of the death penalty now because we all agree it’s bad. This was the jumping off point though, he had thought he would never have to deal with life and death issues again, but they do still exist.

The first story was about a 16 year old Jehova’s witness, who, with his parents, didn’t want a life saving blood transfusion as part of his treatment for leukaemia. The doctors did want him to have the life saving blood transfusion so the case came to court. In some ways it seems like a no-brainer to say of course the child should be ‘forced’ to have the blood transfusion, However, Sir Allan went to visit the boy in hospital, made sure the 16 year old understood the risks and issues, and discussed and listened for some hours. He also wanted to make sure that if he judged  that the child should have the treatment, the boy would accept the judgement and not try ripping the tubes out. Indeed he argued that because the decision had come to him, the judge, this was the heavenly equivalent of a sick note that he could hand over to St Peter at the pearly gates to excuse his sin (I’ve deliberately left the quote marks off there). So when he left the hospital and wrote up the brief on Friday night, the appeals court were all ready and set for the appeal. But there wasn’t one. The family’s solicitor, himself a Jehovah’s Witness, said they had planned to appeal because they had thought their opinion would be dismissed, but when their views and values were taken seriously and listened to, even if ultimately the judge didn’t agree, they were satisfied.

However, there was a sober epilogue. The leukaemia returned 10 years later, and as an adult he refused a transfusion and did die. So the judgement gave him a decade, but ultimately didn’t save him. It seems to me that the boy might have felt that an external court could override him as a child, but as an adult man, his path was clearly to stick with the tenets of his religion.

The second story was the longest and concerned conjoined twins. The parents came from a small village in Malta which has an agreement with the NHS that their complex cases can come here for treatment. You probably heard about it at the time, the twins were Jodie and Mary (not their real names).

The twins were joined up around their tummies with their legs sort of stuck out at the sides and grown all wrong, it did look quite bad. Indeed, very understandably, it took the mother days to be able to be in the same room with them and  to touch them.

Jodie was well but Mary was brain damaged. Jodie’s heart was beating for Mary which doctors suggested was equivalent to her little baby heart pumping blood round a 10 foot tall person. The doctors thought they could save Jodie and carry out complex surgery to give her a healthy normal body. Mary would have to die. I did think this moral dilemma was somewhat reduced by the possibility that Jodies heart could fail under the double strain and they could both die. It seems then it’s choice of saving one instead of none. However, in this or another case it might be that Jodies heart would  grow strong and they could both live, though with a limited quality of life and being bed bound.

So the parents thought they should wait things out and if the babies died that was God’s will, while the doctors were sure they could save Jodie. A very cynical person might wonder if some parents might prefer a dead child to a severely handicapped child and might wonder if this influenced the parent’s feeling that Mary should not be sacrificed (though the doctors were confident Jodie would be healthy, the parents were not so sure).

So it came to court. Three days in Sir Allan raised a further point: if the doctors take up a scalpel to separate the twins and save Jody, but knowingly kill Mary, is that murder?

This could have been argued very differently a century ago. Murder involves killing a ‘rational human’ i.e. I guess killing animals is ok. So was Mary a rational human? Her brain damage would, a century ago, have disqualified her as a ‘monstrous birth’. Perhaps it might then have been perfectly ok to let her go quietly, and maybe even to help her along. Nowadays it was quickly agreed that Mary’s brain damage didn’t apply and she definitely counted as a rational human.

So having described this much, I’d like to stop discussing the actual case, take a step back, and say, I think it’s quite right for the state, for the taxpayer, indirectly for us, to take this time and effort and money to discuss these cases and go into the issues. For example, far better to get into the issues of whether the operation is murder or not before hand, so you can figure it out without any doctor having to sit in the dock and wonder if he will wind up in prison (in the end they decided that because Mary was such a drain on Jodie, and could kill her, it was ‘self defence’ for Jody to be separated and the doctors were acting as a proxy for Jody’s self defence). And after all, if the taxpayer spends a fortune in wages, you do get 20-40% of that right back.

Michael Sandal argued at the end of one of his books on ethics, that when you have a knotty, thorny ethical dilemma, perhaps the exact decision you reach is not the most important thing. The whole point of a difficult choice is that there are arguments either way and that perhaps the most important thing is to honour the difficulty with thought, attention, time and effort. You must think carefully every which way, but ultimately there might not be a clearly right or wrong answer. He illustrated this with two men who each had  brother who had committed murder and might do so again. Ultimately one man dobbed his brother in, while the other refused to do so. In the end you could agree with both men.

However, Sir Allan argued this was not exactly the case for Jody and Mary. The question was not what was moral, the question was, what was legal. And he raised this again in a question at the end. Currently assisting suicide is illegal so if someone brings their wife to a Dignitas clinic in Switzerland, this is illegal, even if we all agree the law needs to be changed (and clearly we don’t all agree otherwise we would change it).

I did wonder about all the cases we never hear about because the parents and doctors agree. If the doctors had just gone ahead without any court cases, would they maybe have been up for possible murder (even if Mary’s death turned out to be indirect self defence) or would nobody have thought to raise the issue?

The difference between law and morals also comes out very well in this paper: No Child Left Alone, about mothers and father who leave their children alone. Surprisingly, it is actually readable, even though it’s science! But don’t worry, no children where harmed in the making of this science. The children were only left alone in scenarios that were read and graded by amazon Mechanical Turk (what a brilliant way to get research subjects). The authors, Ashley Thomas et al., conclude that in the US today there is a new moral code and it’s totally immoral to take your eyes off your child for even five minutes, even when the risk of kidnapping/murder is around 0.0007% or 1/1.4 million a year (fairly low) and that when police were called out to bring two lone children home, the kids were more at risk being driven in the car than they had been walking home alone (with the permission of their parents). This even comes up in Patrick Ness’s new novel More Than This. Two brothers are left home alone for a short time, in those few minutes an escaped prisoner pops by and something terrible happens to the younger brother. The parents then spend the next 10 years blaming the older brother, who was eight at the time. The older brother discusses it twice, and both friends are assure him he was not at fault (obviously) but they are entirely happy to throw all the blame on the mother while ignoring the actual person who committed the terrible crime. That was a bit annoying.

The last author of no Child Left Alone, Barbara Sarnecka, concluded that their findings “should caution those who make and enforce the law to distinguish evidence-based and rational assessments of risk to children from intuitive moral judgments about parents — and to avoid investing the latter with the force of law.”  So leaving your children alone in sensible circumstances (not neglect) is now immoral, but should not be made illegal.

Phew that was a lot of thought from one lecture. I’m looking forward to more of these.

1 year cancer survival: is your cancer more important than your hospital?

Nowadays quite a few health statistics are published online. Here I’ve got some graphs on some cancer stats published this year. The stats take a while to collect so we are only just onto the 2014 data (in the perfect world hospitals would submit a months stats the next month so the annual data could be published by the end of February. We are not living in that world yet. Also we wouldn’t get sick in the first place in that world, which is why it would be so easy to submit the stats).

This set of stats is pretty detailed, it lists the number of patients with each of the ‘big 13’ cancers, at  stages 1, 2, 3, 4 or unknown for each CGG  (clinical commissioning group) in England. Stage 1 is early and good, stage 4 is late and bad. The 1 year survival for the ‘big three’ (breast, bowel and lung) has also been published for each CCG (the % of patients diagnosed in 2013 who were still alive at the end of 2014). It’s interesting to compare these two dimensions by graphing early stage of diagnosis (by adding up all the patients diagnosed in 2013 and 2014, except three cancers are new with only one year of data) against 1 year survival for each cancer for each CCG.


I find it pretty interesting that three such distinct clusters just fall out of the data.

In the bottom left is lung cancer. This unfortunately has very bad early diagnosis with only 14-37% of patients diagnosed with stage 1 or 2 and equally bad 1 year survival. Of all the patients diagnosed in 2013 only 24-47% where alive at the end of 2014, depending on where in England they were.

Colorectal is intermediate, 30-57% of patients are diagnosed at stage 1 or 2 and 68-85% were still alive at the end of 2014.

Breast is best with 72-96% of patients are diagnosed at stage 1 or 2 and 93-97% were still alive at the end of 2014.

I think it’s interesting because the variation across the two dimensions for all the CCGs (each dot in each group) is smaller than the variation between the different cancers (the space between the groups). So which cancer you get will affect you more than any variation that exists around the country. Bear in mind that differences between CCGs, might be due to something about diagnosis/treatment OR they might be due something about the population. Deprivation definitely plays a role, for example deprived areas have a much lower screening, which will reduce early diagnosis. So do the graphs show variation in treatment or variation in populations? This isn’t exactly about lifestyle factors. If you smoke a lot, your odds of getting lung cancer are higher, but what determines whether you are diagnosed at stage 1 or 4? What determines how long you have after that diagnosis?

While we can’t do a similar graph for any other cancers, as 1 year survival is only published for ‘all’ and ‘the big three’, we can look at early diagnosis for the next ten most common cancers.

The same data is shown two ways. The first graph on the left shows the early diagnosis for each cancer lined up by CCG. The second shows each cancer lined up by percentage.


Looking at the first graph you can see that there isn’t much of a pattern, a CCG that has early diagnosis in one cancer has late diagnosis of another. Even if you can’t see that by eye, when you measure the correlations the surprising thing is that virtually nothing correlates with anything else. Of all of the 10 cancers shown, early diagnosis in one cancer in one place doesn’t predict early or late diagnosis in any other cancer (there are a few weak, correlations, but we can round that down to ‘nothing’). The next thing, shown more clearly in the second graph where each cancer is lined up in size order, is that while there is quite a range in the percentage of patients diagnosed early each cancer still has it’s own pattern. Melanoma is best then I’ve listed them in early diagnosis order on the graph.

Lots of things go into early diagnosis. Obviously it’s easier to spot stuff happening to your skin than to an organ buried in a bony cage, which is why melanoma is top of the list for early diagnosis and lung is near the bottom (though not in the same graph). So part of it will be your whether or not you have symptoms, then spotting those symptoms, going in to the GP, or screening to catch things before they start to produce symptoms…

Coming up to the end of the blog post, I’d like to close on the answer to all this variation, ideally with a few simple bullet points that would totally fix the problem. But unfortunately I’m all out of simple answers today (get changes in your body checked out? watch out for random bleeding? spend more money on the NHS?) It’s not that I don’t believe in simple answers, I just don’t have one here. Still if I haven’t got any good answers, hopefully it’s at least a good question.

Fancy meeting you here

It’s quite fun when two completely random books you’re reading happen to match up perfectly.

I’ve slowly been reading Edward Tufts’ Envisioning Information. One of the infographics describes “The slow, costly death of Mrs K”. (I wouldn’t have thought it was an infographic as it is also a wall of text).

The Slow, Costly Death of Mrs K__ ICUpsych

The case is described in Clinical Bioethics,  she lies in intensive care, being poked and prodded, so she can lie in comatose suffering for a month never recovering and so far as I can see, with no hope of recovering. None of those treatments prolonged her life meaningfully, or gave her a better death, however she might have defined that.

And this is half of what Atul Gawande’s book, Being Mortal is all about (because the ‘some doctors questioning the practice’ in 1984 evidently didn’t have much influence. Hopefully writing a best selling book questioning the practice will have more luck).

The first half is elderly care, equally fascinating, and very current for our aging populations. However it was the end of life care that I found most fascinating.

Atul highlights the difference good end of life care can make comparing two cancer patients and also his own Dad who had cancer, and how important it is to ask the patient the difficult questions and make it clear if they are up against a rock and a hard place. Not a rock and a cure.

He compares the two surgeons who advised his Dad on the rare spinal tumour that was squashing his spine and causing pain and paralysis. One surgeon advised instant action because he could be paralysed any minute and the surgery could cure him. The other surgeon pointed out that the surgery could equally maim or kill him and that these cancers usually grow quite slowly so he should hold out until the current pain and paralysis was intolerable enough that the risks of the surgery became more acceptable.  And the tumour was slow growing and Dr Gawande had two or three years of good life and good work (very important to him) before the surgery. In hindsight the operation went well and he had some more years after that, but that could never have been guaranteed.

Atul also told the story of two cancer patients, and how hospice care, provided in addition to normal cancer care, can actually prolong life (shown to be the case in the US). Part of the benefit was that the palliative care team could train the patient and their family in simple medical procedures so when the inevitable next step came along, they were prepared, knew what to do, had the medication to hand, and could cope. When the second patient became very breathless, without the hospice care they didn’t have oxygen at home, or the training in what to do, so they rushed into hospital where she was put her on as many machines as possible, leaving it to the family to decide when it was time to unplug her and denying her the the death at home she had wished for.

Atul also describes two such home deaths, of his father and of a patient, where, by fully understanding her wishes, he had carried out a much smaller scale surgery than he might normally have done so she was well enough to go home.

In order to fully understand the patients wishes you need to ask the right questions and Atul spelled out what he learnt (here it is in checklist form).

When you want to open up the conversation say: “I’m worried”. Then ask at each stage

  • “What is your understanding of the situation and it’s potential outcomes?
  • What are your fears and what are your hopes?
  • What are the trade-offs you are willing to make and not willing to make?
  • And what is the course of action that best serves this understanding?”

Sitting here writing/reading a blog you can see that these are incredibly easy questions to write down/read out. Applying them in real life probably takes a bit more practice. Indeed Atul was inspired to make the effort after remembering some pretty gruesome ‘wrong’ decisions made by patients who might have mistakenly thought the huge surgery would ‘save’ them rather than ‘give them back bladder control for the last few weeks of life’.

In Almodovar’s All about my Mother we see the Spanish doctors go through quite a lot of training on how to ask family to donate the organs of their loved ones. The people playing the family members think up lots of difficult, and racist, questions to train the doctors.

These are also questions any family member can ask. One story concerned someone who, despite working in this field nearly couldn’t have this conversation with her own Dad. On the way home she realised her mistake and went back to ask him, ‘what is the most important thing for you now’. He replied that as long as he could watch sport on telly and eat ice-cream, life still had meaning for him. When he was in the middle of surgery and the doctor asked the daughter what they should do, she know what the criteria were. If it goes wrong will he still be able to watch telly and eat ice-cream … ?


It’s too hard, just don’t bother

I was just reading Walter Mischel’s book on Willpower, The Marshmallow Test. He’s the one who invented the test and they also did loads of work on how children could increase or decrease their waiting times (it wan’t always a literal marshmallow, but that’s the shorthand he uses).

I’ll outline the test here. The child is seated in an empty, dull room, In front of them is the marshmallow to resist and the two marshmallows they can get if they do resist. To get the single marshmallow now they have to ring a bell to call back the researcher and they’ve been shown the researcher will return the second they ring the bell.

Then they did all kinds of variations to see what would help or hinder willpower. Obviously putting the marshmallows out of sight helped, but another experiment showed that is only obvious for older kids, if you asked the medium kids they thought it would help to be looking at them (it didn’t) and the little kids didn’t understand the question. The sweetest story was a little girl who worked so hard to resist the one cookie to get two, that she then didn’t eat those two at all, but waited even longer to take them home to show her mum what she’d achieved. Further experiments did indeed show that if we reframe the temptation (including literally putting a frame around it and pretending it’s a picture) it can help.

Mischell also discusses how temptation can be modified by your motivation. This part is reassuring as he questions Tierneys experiments that show willpower is depletable and depends on blood sugar. He argues that their students were just bored by the second willpower test, and that if we believe willpower is depletable it is more depletable than if we believe it is an infinite (like Gretchen Rubin’s short story about horseshoes bringing luck even if you don’t believe in them).

The example Mischel gives from his own life was the one that surprised me most. He got symptoms went to the doctor, was diagnosed with celiacs and given a pill. That seemed odd as I didn’t know there was a pill for it. Months later he found out in the library (before the days of google and wikipedia) that celiacs was caused by gluten intolerance. Asking his doctor why he didn’t tell him the cause and why he didn’t just give up gluten the doctor replied, Nobody has the self-control needed to stay on a gluten-free diet in a gluten-filled world, so there was no point talking about it (the pill could alleviate the symptoms a bit but had it’s own, possibly serious, side-effects). Needless to say plenty of people, including Mischel, manage this nowadays. They resist temptation by the cognitive reframing that makes gluten a poison (helped a lot by the fairly immediate crippling stomach pains).

It was quite surprising that the doctor had such low expectations of what the patient could achieve, naturally if you don’t even try, you will achieve even less. And I think this shows that we can achieve much bigger changes than you might think as long as you are convinced enough.


Mindless eating

I’ve just read Mindless Eating and it’s pretty interesting, though I’m not sure if agree with all of the premise.

The premise is we can stop getting fat by eating less and we can change our environment to make that happen without our noticing it and feeling deprived (obviously I agree with that part). In fact this is where Dan Ariely says free will comes in (Behavioural Economics Ate my Dog). We tend to rather blindly follow cues from our environment, and never notice the extremely powerful effect it has on us (countless food related experiments in Mindless eating) yet we can control our environment. And the good thing is, once you have done the upfront thinking, considering and planning to set up your environment, you can relax and mindlessly follow your new ‘rules’ (also the point in Willpower).

Brian Wansink researches how much we eat in various set ups. They have experiments in labs (which look like living rooms) and fake restaurants, with hidden scales everywhere to weigh what you eat.
I liked the one about portion sizes, where if you give someone 200 M&Ms in a bag they will eat an average of 73 in an hour but if you give them a bag with 10 bags of 20 M&Ms people will always finish a small bag, but they will eat less of them averaging 42 M&Ms. So if you want to buy in bulk you should always portion out helpings into smaller containers. So we might want ‘one’ of something (or three!) but the the size of that ‘one’ is quite flexible. I’ve found this myself with a tray bake birthday cake cut into squares which were further cut into triangles. I would have been perfectly happy to eat a square, but one triangle was one piece so I ate just one piece.

Though the book has lots of good useful strategies to eat less without feeling you are eating less, in some ways I felt the book was at cross purposes to a healthy diet because it doesn’t use my strategy. It discusses how to snack less when watching telly, but it never considered whether, maybe, we should just not snack! (to be fair it does discuss how not to snack before dinner). Because not being able to stuff our faces with sweets at all times will make us feel deprived. In fact the people in the book are faced with such a barrage of snacks (all unhealthy) you really understand how difficult it is for people in the US to eat sensibly.

This reminds me of Gretchen Rubins’ book Better than Before on how to foster good habits. One method is abstinence, avoiding something altotether, may be easier than moderation. And having ‘bright line’ rules for what you do and don’t eat can protect you even in this super-food-saturated environment. So rather than putting your snacks into small bags, you could having a rule of ‘no sweets’ or ‘only have sweets as an actual pudding after dinner’ or (my rule) ‘no snacks, except almonds or birthday cake (about once a fortnight), but also eat proper meals so you are not hungry. Faced with the absolute barrage of junk like the people in the book, I could feel how my rules would protect me and simplify my choices (just say no. I’m not saying it wouldn’t take a bit of willpower, if I was faced with the vast amounts of snacks, like the people in Mindless Eating I’d probably end up faffing more, but abstaining would protect me from the snacks).Dilbert Limit to potato chips a human can eat

I wonder if the obsession with snacks is a US thing. In one case they said that when ‘European’ researchers joined the food lab they were surprised that they could do experiments at any time of day because people were willing to eat at any time, while those researchers were used, at home, to only do food experiments at breakfast, lunch and dinner.

Even Hercule Poirot agrees:

Alas that one can only eat three times a day. If one partakes of the 5 o’clock one doesn’t appreciate the dinner with the proper quality of expectant gastric juices. And the dinner, let us remember, is the supreme meal of the day.

When is your deathday?

Funnily just as I was joking about the website from the IT crowd where you enter all your details and it gives you your deathday (3pm Thursday if you don’t eat your greens, also the motherless ovens is driven by Scarper Lee’s impending deathday), I’ve found out that we can all access the system the GPs use to calculate our risks of cancers or heart disease (caveat caveat, don’t use it without your doctor…). The GP one sits inside their system and can safely use your data on your GPs database. The one we can use just sits on the website and you have to enter you data yourself, but it’s a really simple one page checklist. On the symptoms checklist, out of 19 options, blood comes up 7 times depending on where it is. It’s as if random bleeding is a bad thing. The postcode is used to estimate your deprivation. It could be an idea to compare the numbers you get with the numbers your GP gets. If your numbers are lower perhaps the GP is missing some family history. Also, who would have thought that difficulty in swallowing is more of a risk factor than a family member with type 2 diabetes and a family member with breast cancer put together? Who even knew difficulty in swallowing was a thing? These three risk factors give you a sprinkling of frowny faces on the overview panel if you are 68, but not if you are younger. The moral of the storey is that staying young is the best way to avoid cancer, it’s also good for Hollywood careers, so really, we should all follow Orlando’s example (not Bloom).

Though I was a bit dismissive of caveats above it’s interesting to note that though the system was built using (anonymised) data from 2.5 million people, it is still only sensitive enough to give meaningful risks for the ‘big 10’ cancers (the ones on the list when you click calculate) and it’s not good for rarer cancers (yet, adding more data will help). Also the tool is created with data from 25-80 year olds, so is only suitable for those age groups (I’m pretty sure bleeding randomly is bad whatever your age though! Get that checked out).

My impression of how useful a tool like this is, is influenced by a tool to predict genetic causes of diabetes (e.g. MODY). While the overwhelming majority of diabetics are now Type IIs and Type Is are next (their pancreas has been knocked out, most likely by the immune response to a mystery virus), there is a small category of people whose diabetes is caused by a mutation, and if you can identify these patients, it may change the way they are treated. For example some people just have a tiny stunted pancreas. Giving these people drugs to squeeze out more insulin from the pancreas probably won’t work and they should probably go straight onto insulin. Some people have a permanently higher blood glucose, but the body works perfectly well to maintain that higher level. A bit as if your body thought your body temperature should be 38 degrees. It is crazy hard to bring these levels down, and luckily it seems to be unnecessary, these people seem to be at no greater risk of long term conditions. so these ‘diabetics’ need to not be treated. And best of all is the condition setting in before six months (before you have a functioning immune system that could kill your pancreas) where you have the blood glucose sensing system, you have the insulin producing system but they are not connected. They can be joined back together by massive doses of sulphonylureas (basically a pill) which will eliminate your need for testing your blood sugar and injecting insulin. Almost a ‘cure’ for this tiny minority of a tiny minority. The point about algorithms here is that Prof. Andrew Hattersly who has led the research into these conditions, who can safely be considered an expert on genetic causes of diabetes has tested himself against the algorithm he built and he found the algorithm can guess better than he can. So swing on over if you’re diabetic and have family member with diabetes and want to review yourself.

So with this endorsment for one algorithm, I’m inclined to believe a different one can probably at least flag up useful pointers.

This can further be tied to the outguessing machine described by Poundstone in Predicting the Unpredictable. The machine was built in a pre digital age (the ’50s) and by simply remembering whatever you guessed the last two times a given option came up (with a 16 bit memory), it could consistently outguess anyone. Because (from Thinking Fast and Slow) multiplying lots of small numbers in our head is not a major human skill, so leave it to the algorithms.

I’m gonna live forever (till 90)

ONS has taken their population predictions, allowed you enter your date of birth and gender and they can tell you how long you get to live. Pretty neat. Also much better than the one in Series Two from the IT crowd. Though that one took into account how many portions of veg you ate the ONS one gives you better numbers (more than a week).

A life expectancy of 90

ONS is giving me 90 years, while my grandmother lived to 92. I thought this was part of my generation being the first to not live longer than the previous one due to our terrible obesity epidemic, but the odd thing is that I get a better life expectancy than my mother, and nearly double her odds of living to a 100.

So wow. 90 years! I feel a bit like Artie in Narbonic.

Narbonic Six Months to Live

(Artie was originally a gerbil with a normal gerbil lifespan before Helen decided he could better carry out dashing rescues if he was bit bigger).

ONS is mainly motivated by showing you how much you need to save up for your pension (and probably preparing us for the inevitable moving back of state pensionable ages).

This was also a theme in Patrick Susskind’s Parfume. (I can’t remember if it made it into the film as a theme, and I think they skipped his childhood anyway). The theme was that everyone who had any long-term contact with the Grenouille (the protagonist) died a miserable death (but randomly, due to fate or magic realism. He did go round killing people, but that’s another theme). In his early years he was brought up quite neglected with not enough food or warm clothes (as I recall). This was because the woman who brought him up at a sort of private orphanage skimped on the children to save the money she was given for them for her old age, but she lived and lived and lived, so she did die in public hospital sharing a bed with someone else and was buried in a mass grave, her greatest fear.

So, um, better start saving, but index funds only!

An anti-fairy tale,

I recently read Beautiful Darkness, by Fabien Kehlmann & Kerascoët, translated from the French. The artist Kerascoët is really two people, Marie Pommepuy and Sebastien Cosset and the story is based on an idea by Marie Pommepuy. And what a great story. I must have read it 10 times in the last week (it’s not that long).

Starting with a tete-a-tete over hot chocolate and cake, a disaster forces the heroine to escape through dank, creepy, slimy collapsing corridors to freedom in forest. Freedom from a little dead girl lying in the woods with hundreds of tiny people climbing out of her eyes and nose and mouth. This is some of the anti in the fairy tale. We never really learn what ‘before’ was like. But these little people are woefully unfit to live in a forest, victims of cats, birds and ants, they nevertheless try to make a world for themselves. The origins of these little people is never explained, you probably can’t think too hard about it. They had sofas and clothes and teapots, so they must have lived in some kind of psychic space inside the girl (called Aurora). They know what sunstroke is and at least one of them can read. It seems that most of them didn’t know each other until they all ended up in the forest together.

The blurb says it’s a searing condemnation of our vast capacity for evil writ tiny. But the winnowing down of people is not just by each other, it’s mostly by the ginormous forest creatures. Even the plants are dangerous. One little creature (little girl?), turns up with a itchy swollen hand, later her entire arm and half her face is swollen, next she is swollen all over, then we never see her again (so attention to detail and rereading it a few times pays off). Keep an eye out for the triplets/twins (I didn’t notice the twins used to be triplets on the first read), their conversion from triplets to twins is one of the more horrible scenes (in a good-story way). And there’s no evidence that anyone becomes evil once civilising influences are off, the impression was more that they were themselves (evil or good) all along, only now they are up against the wall (the forest, then winter).

It’s interesting to read online reviews, Zainab suggests the four main characters can be seen as Auroras conscientiousness, psychoticism, neuroticism and openness to new experience. But the comic is more about questions than answers. What would that make all the other little people?  (their-six year-old self? their enjoys-pulling-legs-off-insects self?). While it’s interesting to think about, they are not a straightforward representation as seen in Narbonic (definitely read that review as well, it’s really good, also do read Narbonic too).

Narbonic sprites

I’ll close with a picture of something that didn’t happen. We see Aurora waking up and going home. That’s what should have happened. We never find out why it didn’t.

Build character, without doing something you hate.

I was just reading Willpower by Baumeister and Tierney, which I enjoyed a lot. For some reason I had very good willpower while I was reading it. They take the idea that intelligence is supposed to be a good thing in life, but that actually ‘resisting the marshmallow’ or willpower also has a really strong correlation with ‘success’ (listed in the link). And that willpower is much more amenable to practise.

They point out that ‘willpower’ is the same thing you use for decision making and resisting impulses and we have limited supplies of the stuff. So starting 10 new years resolutions, that each require willpower, is impossibly hard. Do one at a time. They describe Franklin, who helped inspire Gretchen Rubin’s approach to her happiness project. He had a list of 13 values and each week he’d focus on one, slipping behind in the one he’d done in the previous week, but hopefully doing two steps forward in each focus week and only one step back in between, so that:

“On the whole, tho’ I never arrived at the Perfection I had been so ambitious of obtaining, but fell far short of it, yet as I was, by the Endeavor, a better and a happier Man than I otherwise should have been if I had not attempted it”.

The funny thing is that the recommendations end up really supporting religion. Lots of religious practices, meditating every day, praying every day, praying five time a day all add up to practising willpower. It seems that anything you do because it’s the right thing to do, whether or not you feel like it, is practising willpower. Or you could say that because you don’t feel like it you build character And the work done here gives you strength to do more good things in a virtuous circle.

Calvin and Hobbes build character

They also mention that the more tidy our environment, the more self control we have. In the study they quote you can be offered some money now, or more money in a week. People in tidier surroundings are more likely  to choose to wait a week.  This is funny as Gretchen Rubin studied the effect of clutter on happiness, pointing out that clutter is all over the popular press (blogs) but is not studied much, yet keeping clutter under control is an essential, foundation, habit so around 2011 the science caught up.

It might seem really obvious but I’ve also realised that reading about something, helps you think more focusedly on that subject. So while I was reading stuffocation, I decluttered (even thought the book is only partly about that) and while I was reading Willpower, I was keeping better habits. This suggests that constantly reading different books on the same subject can be useful at practising that subject, even if the books are not adding any new information. Even though I’ve decluttered reasonably well (though not as well as if Marie Kendo really came round to my house to say are you sure that brings joy to your life), it seems that reading a decluttering book every quarter would be a good way to inspire you to keep on top of things. Finally an excuse to get more of these books.

The final sentence is to point out (despite the Calvin and Hobbes strip) that I don’t think it is at all necessary to do pointless tasks to build willpower. In life and in the world, there are enough useful tasks that need doing, and helpful habits that can be built up, there is no need to build character just for building characters sake. Build character by building a habit of something useful and worthwhile (writing blogs?).
