Is being overweight good for you?

August 11th, 2018 | Health & Wellbeing, Science

The idea that being overweight is bad for you is well established. Being overweight takes years off your life, so it’s important to eat right and exercise to keep your weight under control. More recent evidence, however, has challenged this.

For example, a 2013 paper in the Journal of the American Medical Association found that overweight people had a lower level of all-cause mortality than people of a healthy weight. The paper was not well-received, but nobody seems to have been able to poke any holes in it, either.

Similarly, a 2009 systematic review published in Deutsches Ärzteblatt International concluded that:

The prevailing notion that overweight increases morbidity and mortality, as compared to so-called normal weight, is in need of further specification.

So, should we give up with the diets and let our waistlines expand a little? Maybe. But even if more evidence goes on to support these findings, there are some good reasons for sticking with the current line on what a healthy BMI is.

Overweight vs obese

Something that all the studies agree on is that people have worse health outcomes, including death, if they are obese. Overweight is one thing, but being obese is bad for you in any study.

And you might be surprised how easy it is to reach the category of obese. Consider that my BMI hovers around 24. 25 is the line between healthy weight and overweight. So, I’m nearly in the overweight category. And I look like this:

Not the buffest individual, that’s for sure, but I don’t look like I’m carrying around any extra weight either. And you only have to move up to a BMI of 30 to go into the obese category.

All-cause morality

As the NHS points out, these studies typically look at all-cause mortality, which means people dying of anything. The problem is that this contradicts individual studies of any topic. For example, if we look at heart disease or diabetes. Whenever we look at the individual causes, we find it is better to be a healthy weight.

There is a huge amount of evidence to support this, so in order for us to accept an alternative view, it would ideally need to explain this discrepancy.

Quality of life

The second problem is that these studies just look at mortality. But that is never the way that NICE or Public Health England have looked at how to provide the most efficient healthcare system.

We measure outcomes in quality-adjusted life-years (QALYs). It’s not enough just to be alive. Modern medicine allows us to keep pretty much anybody alive indefinitely. But sitting in a medically induced coma on a ventilator isn’t a life that any of us would choose.

As a study in Nature points out, being overweight is associated with fewer years of disease-free life. In short, you might experience a longer life, but it won’t be a happier or more fulfilling one.

Indeed, this could help explain the findings. If people are already inside the medical system because they’re having to be treated for obesity-related illnesses, we may be better at spotting other diseases. Or it may be that carrying around some extra weight will reduce your quality of life but also help you to stick around for an extra week when you become seriously ill because you have larger fat reserves.

Conclusion

There is genuine evidence that you will live longer if you are a little overweight (but not obese). However, so far we have been unable to explain why this is. And, more importantly, you will also have a reduced quality of life. Therefore, the current guidelines on maintaining a healthy BMI are still relevant.

How long do HRM-Tri batteries last?

August 10th, 2018 | Sport

The HRM-Tri is a chest strap heart rate monitor produced by Garmin. But how long does the battery last?

Garmin gives different estimates. On their website, they say ten months:

Battery life: 10 months (Tri training 1 hour per day)

While on their YouTube page, then say 18 months:

The CR2032 batteries in your HRM-Run, HRM-Swim or HRM-Tri straps will last approximately 18 months, depending on use.

I only got my hands on a Garmin device at the end of January, which means I have been using the HRM-Tri for six months. Today, while running, my watch told me that the battery on the HRM-Tri was very low.

So, that’s somewhat shorter than they claim. Luckily, however, it is easy enough to change the battery and it uses a standard 2032. Here’s a video:

Make sure you don’t drop one of the screws. Otherwise, you’ll be in a desperate search to find it before your toddler eats it.

Finland nutrition

August 9th, 2018 | Food

While I was over in Finland, I raided their supermarkets for the sports products they had. Some of it was Finnish, some of it was American. Here is what I found.

Gatorade

I’ve never tried Gatorade before but it thumbs up. I like this stuff. It doesn’t feel as heavy as Lucozade.

Powerade

Another widely sold drink that I’ve never tried. It was good, but I prefer the flavours of Gatorade.

Maxim protein bar

This was very tasty. Almost as tasty as the Carb Killa bars.

Arla protein yoghurt

Chocolate and orange flavour. it definitely has a distinctive taste compared with other yoghurts, but in terms of mixing up my recovery food, I could see myself throwing in some of these.

Tupla protein bar

This not only looks like a Mars bar (but has no relation) but also tastes like a chewy version of a Mars bar. All of which is good.

Cricket protein bar

These are named Leader Zircca bars. Leader is the brand, and zircca is the Finnish word for cricket. Not the game, but the insect. It’s made of crickets: 15 of them go into each bar. They were okay and didn’t taste like you were eating insects, but I haven’t left craving more.

Venla’s trip to hospital

August 8th, 2018 | Family & Parenting

Last week, Venla had what appeared at the time to be a seizure (she’s totally fine by the way, in case you’re worrying!). So, taking no chances, the daycare rang for an ambulance. It’s standard procedure for under-twos to be taken to hospital. Here are a few observations.

The NHS staff were lovely

At every step, we ran into nice people. It started with our paramedic who I loved, not just because his name is also Chris, but also because he too could make a passible career as a Ross Nobel impersonator.

Everyone was good with kids and happy to see Venla. Now, you might think that was a given, given that we went to children’s A&E and then the children’s observation unit. But, when Elina gave birth to Venla, one of the pediatric consultants came around to check on her and he was completely flummoxed by her clothing fastening system, complaining he always got it wrong. Apparently, you can work with babies for your whole career and still not really know what to do. None of this this time.

Hospitals are ill-prepared for healthy curious children

Venla was pretty unhappy at daycare and in the ambulance (constantly switching between crying and excited yelling “in a nee-naw!”) but once we got to hospital she quickly returned to her usual self.

This was okay in the waiting room where they had toys and walls to contain her. But once we were in an examination room, or worse the ward of the CAT unit, she couldn’t care less about the toys. All she wanted to do was touch every expensive medal device and open every draw she could find.

She could easily do this because many of the draws were placed at an excellent height for a toddler. Worse, many of them were open-sided to allow medical staff to grab items quickly in an emergency. It also allows toddlers to grab things.

It occurs to me that hospitals are used to dealing with docile sick children who cuddle up with their parents. Or maybe who feel well enough to push some buttons or do a bit of colouring. But a curious child like Venla, who feels back to her full strength. That has trouble written all over it. After five hours of chasing her up and down hospital corridors and around hospital wards, we were both exhausted.

There is a lot of inefficient beaurcacy

At least it feels inefficient. Maybe it is there for a reason. But I was ill prepared for the whole process.

When we got to daycare, the daycare staff were telling the paramedic what had happened. I assumed the paramedic would be taking notes and these notes would then be handed on to the rest of the hospital staff.

But we were asked to describe what had happened. Even though we weren’t there. When I was getting a brief summary from the paramedic and the daycare staff, I didn’t realise that I should have been taking notes because I was going to be tested on it later.

But apparently, I was. First by the nurse in A&E, then the A&E doctor, then the A&E nursery nurse, then the CAT unit nurse, then the CAT unit doctor. Even though neither of us had witnessed it. Why the notes weren’t simply handed over is unclear.

The whole thing was free

It was nice to be left with a bill of £0, which would have been tens of euros in Finland, or tens of thousands in the United States. Which, for a Friday night out as a family, seems like a cheap win.

Finland running

August 7th, 2018 | Sport

Going on holiday has always been a tedious chore, but now that I have a training schedule, it’s even more of a headache. What’s wrong with home, where there is an adequate supply of toilet roll in a brand that you have tested and trust?

That said, it was nice to run somewhere other than the Leeds Liverpool canal. As beautiful as it is, a chance is often welcome.

I did two runs while I was other there, one up to Lake Lahti, and one to Soukainen and back. It was so warm that I had to be out the door at 6:30am for my first one and wait until gone 9pm to start my second one.

Even then, I found it hard going. Despite the second run only being 10 kilometres, I couldn’t hold a 5:00 per km pace, and something about the heat or the extra hydration I took on to compensate for that upset my stomach.

Importantly, though, I didn’t get eaten by wolves. Which I found out afterwards that Elina’s mum was quite worried about.

24.1 kilometres

August 6th, 2018 | Sport

Last month, I went out for a 24-kilometre run. Specifically, I went out for a 24.1-kilometre run, which meant I would set a new distance record by 0.1 of a kilometre.

It was the day the rains came after the long heatwave. I set off at 7:30am and given it was so early on a Saturday morning and raining heavily, you might think I would have the canal towpath to myself. But other endurance athletes are, of course, as crazy as I am.

The rain continued, including two brief but torrential downpours that left me soaked to the skin. Thankfully, I had lubed in the correct places to stop any chaffing and despite my ankles being a bit sore from driving in Finland, I felt fine in all respects after the run. My 162nd Parkrun featured in the middle of it.

The levels in the Leeds Liverpool canal were shockingly low. You can see some of it from the photo, but it’s not the clearest example. At some points, it was a good half a metre below the usual level.

I could clearly see the bottom for long stretches. No bodies, thank god. I did see several hundred tyres, though. They were every metre for a good hundred-metres. There were so many in there, I wondered whether they were put in there intentionally because it must have been a massive fly-tipping exercise to get them all in.

You can check it out on Strava here. And, while you’re there, why not follow me? Please be my friend, your kudos are the only thing that validates my ego…

I was getting ripped off for electricity, and maybe you are too

August 5th, 2018 | Life

Last month, Ofgem decided that EDF Energy were ripping me off so much that they forced EDF Energy to send me a letter telling me how much they were ripping me off and that I should switch to a new provider immediately.

When I first got the letter, I was annoyed.

First, this was now something I had to deal with it. Until now, I had been telling myself that when I moved in, I did an energy price comparison and found that EDF was the cheapest supplier. And they had been at every other property I had ever sorted electricity out for, too. So, it seemed logical they would still be the cheapest.

Second, I then felt like an idiot for not doing anything about it for so long. Especially given it literally took me less than five minutes to switch providers, from first putting in my details to getting to the “congratulations” screen.

So, the whole business has made me feel crap.

But, on the plus side, we’re not switching to Bulb Energy, which is going to save us several hundred pounds per year. And they use 100% renewable energy, which means I can feel morally superior, too.

The moral of the story is that even if your provider has been the cheapest in the past, it might not be now. No doubt it is engineered to be this way. According to Which, smaller providers typically have higher levels of customer satisfaction, too, so it’s worth putting your details into a price comparison site once a year. Or now. Now is a great time.

Snapped sunglasses

August 4th, 2018 | Life

Last month, in an effort not to have to spend hundreds of pounds on some cycling sunglasses, I ordered a £10 Bolle-style pair from Ali Express. They looked awesome.

Then, when I told my friends, one of them pointed me to this story on Cycling Weekly about someone who was almost blinded by a pair of knock-off Oakley’s that snapped during a crash.

Heartbroken, I went back to my Aldi special buy sunglasses. They were told in the UK and would, therefore, be subject to EU legislation, so no problems there I thought. Literally, the week after, this happened:

It didn’t happen in a crash, thankfully, it happened while I was putting something into my bag. However, I was still rather surprised about how little force was required to snap them in two, as I wasn’t jamming anything in hard.

So, the search continues. Hopefully, Roka will expand into the UK, and offer everyone a 90% discount to celebrate, sometime before September.

A psychologist watches Love Island

August 2nd, 2018 | Distractions

A few weeks ago we did a writing retreat for everyone on the masters programme in the School of Psychology. During one of the breaks, everyone was talking about Love Island. Somehow, they convinced me it was a subject worth study.

This isn’t unusual. Take Benefits Street, for example. That has all kind of implications, stereotypes and editing choices that provide a deep, rich dataset for social psychologists looking to elucidate and explain the way our society works (or does not work).

So, with Venla safely tucked up into bed, I headed over to ITV’s On Demand service and watched some.

I made it as far as the first “re-coupling” before I had to give up.

What is it?

If you haven’t seen it, here is a quick overview. The show’s producers have rented a giant villa. They then fill it with single people who they hope will have sex on television.

But it’s more than that. It’s a game show. They start by introducing five men and five women and couple them up. They then introduce a sixth man who has to “steal” one of the girls, and they become a couple. Each couple shares a double bed in the communal bedroom, and the person who is left over has to sleep by themselves.

They then introduce more sets of men and women in such a way that there is always a slight imbalance. At certain points, there is a “re-coupling” in which one gender has to select who to couple up with from the other gender, and the person who is left out is sent home.

At the end of the show, the public vote for the couple they like the most, who are given £50,000.

Why is it terrible?

At best, it is uninteresting. It is a bunch of shallow people doing nothing with their time but gossiping, moaning about relationships. drinking and playing ridiculous games.

At worst, it is far more ominous. They’re not shy about the tasteless nature of the show. In one of the organised games, for examples, the girls had to try and crush a watermelon with their bottom by bouncing up and down on it.

Yeah, it was a real thing that really happened:

Worse, though, are the ethical implications of the show.

If I went to the university ethics committee and said I wanted to make people pick who to couple up with, leaving one person purposely excluded, and then continued to strategically introduce other people to break up the existing relationships and make people cry on camera, I would quite rightly be burnt at the stake.

And at least I would be doing it in the name of science.

Because who would possibly subject their fellow human beings to that for the purposes of entertainment? It has been running for six series so it’s not like they can possibly be surprised when the poor people break down in tears.
