Why being 'overweight' means you live longer: The way scientists twist the facts.
             by Dr. Malcolm Kendrick, M.D.

I have been studying medical research for many years, and the single most outstanding thing I have learned is that many medical "facts" are simply not true. Let's take as an example the health risks of drinking alcohol. If you are a man, it has virtually become gospel that drinking more than 21 units of alcohol a week is damaging to your health. But where did the evidence to support this well-known "fact" come from?

The answer may surprise you. According to Richard Smith, a former editor of the British Medical Journal, the level for safe drinking was "plucked out of the air". He was on a Royal College of Physicians team that helped produce the guidelines in 1987. He told The Times newspaper that the committee's epidemiologist had conceded that there was no data about safe limits available and that "it's impossible to say what's safe and what isn't". Smith said the drinking limits were "not based on any firm evidence at all", but were an "intelligent guess".

In time, the intelligent guess becomes an undisputed fact. On much the same lines, we have the inarguable "fact" that being overweight is bad for your health. I should say that, by definition, being "overweight" must be bad for your health – or we wouldn't call it overweight. But we do not define overweight as being the weight above which you are damaging your health; it has an exact definition.

To be overweight means having a BMI of between 25 and 30. Not as bad for you as obesity, but still damaging. Why else would all hospitals and doctors surgeries have BMI charts plastered on the wall with little green squares, orange squares and red squares? Green is normal weight, orange is overweight and red is obese. Even Wikipedia confirms this: "The generally accepted view is that being overweight causes similar health problems to obesity, but to a lesser degree. Adams et al estimated that the risk of death increases by 20 to 40 per cent among overweight people, and the Framingham heart study found that being overweight at age 40 reduced life expectancy by three years."

You can also find papers in prestigious medical journals such as the Journal of the American Medical Association (Jama) with the following headline: "Excess deaths associated with underweight, overweight and obesity." That certainly suggests that overweight is bad for you. However, if you look more closely at the paper in Jama, we can find these words: "Overweight was not associated with excess mortality." (My italics). Perhaps more extraordinarily, what the researchers actually found was that those who were overweight lived the longest; they li...
