No. Yes. For fucks sake, what is wrong with the media? Lots, I suppose, but I’ll concentrate on their innumeracy and credulousness for now. I will also cover their prejudice and scientific illiteracy. Which is a lot to do in under 1000 words, but when you’ve such densely packed stupidity as our Obesity Crisis Bleughly etc. you can really go to town.
First, a little history lesson: in 2007 a report commissioned by the government stupidly predicted that if people continued getting obeser at the same rate by 2015 36% of males and 28% of females would be obese. By 2050, 60% of males and 50% of females would be obese. By the end of the century everyone would be obese and robots would need adamantium reinforcements to maneuver the nation’s vast bulk. A nightmare scenario, I’m sure you’ll agree. Here’s the chart:
Yesterday, the National Obesity Forum stupidly updated that stupid extrapolation. Rather than half of Britain becoming obese by 2050 they believe this will happen much sooner and that we need to something about this. Especially for the children. It’s always for the children (or the women). Their report helpfully recommends negging on fat people, bullying children who don’t like PE and the creation of government sinecures for ex-Forum busybodies.
To come up with their dread warning, they’ve used an extra five years of data from the UK to update the projection above. It’s a projection not a prediction because of the data they leave out. If they included data from the US their scaremongering would fail and these busybodies might have to get real jobs: America’s stopped fattening. We don’t need to hypothesise about how fat we could get, we know. None, none more fat.
Something that can’t go on forever, won’t. That’s a simple thought, but scaremongers know when you’re scared you don’t think. Waistlines can’t expand forever. Eventually a population has to stop getting fatter and now we now know when this happens. America, the land where everything’s big, is no longer the land where everything’s getting bigger. When a third of a society get obese obesity levels off.
Predicting that half of Britain will become obese, when we’ve recently discovered the obesity event horizon should earn you derision. Instead it gets you wall to wall coverage. Incapable of crunching the numbers, the press report as fact a ludicrous projection using incomplete data and biased methods. I don’t want you to confuse my anger with surprise, this is par for the course. Innumeracy and credulousness covered, let’s talk about the press’s prejudice and scientific illiteracy.
Being fat is unhealthy right? Wrong. Okay, not fat, but being obese is bad, right? Wrong. Dead wrong, in fact. And I have a meta-study to prove it.
The words “I have a meta-study” should inspire joy or dread, depending on your position. A meta-study is a study of studies and they’re incredibly useful. You can read more halfway down this old post on how they save lives and reveal truths that might otherwise be hidden.
We’ve been looking at obesity for a very long time, and lots of individual studies have been done, but each has its own problems and each has its own margin of error. Collating several studies allowed researchers to look at 3 million subjects, from 12 countries, and use only the best data to assess the effects of weight gain on health.
The results might surprise you. They found that people with a Body Mass Index of 18.5-25, the “healthy” people, have higher mortality risk than every group of people up to BMIs of 35. The obese were less likely to die than the “healthy” people and the overweight people were significantly less likely to die than the “healthy” people.
Pick a random 5’4″ woman weighing 8 stone (remember to say hello). She has a higher mortality risk than a 14 stone woman of the same height (say hello to her too). You might be incredulous, you might even be angry: but I have a meta-study.
The below table isn’t very layman friendly, but click through to the paper, or read this op-ed, if you don’t believe me. I’m not saying you should gain weight, or lose weight, I’m saying that weight is a particularly poor indicator of health and that you should care about your weight a lot less. Especially care less about other people’s weight.
Not only are predictions of a looming obesity crisis based on nonsense maths, they’re based on nonsense science and reported by a nonsense press. The press are incapable of holding people with a shiny pdf and a slick press release to account. Because of this its all too easy for people to be bullied and for public health (physical and mental) to suffer.
