Trying to control our waistlines is beyond the government’s power

James Cracknell, the athlete turned anti-obesity campaigner, was the subject of sniggering and derision in April when he said that North Korea and Cuba had got a ‘handle on obesity’. With impressive understatement, he attributed this to both countries being ‘quite controlling on behavioural trends’. It was a bad point poorly made, but in a roundabout way he drew attention to the major obstacles faced by those who want to reduce obesity rates in the rest of the world: freedom and affluence.

Only Venezuela was missing from his list. Its people lost an average of 19 pounds last year as its basket-case economy unravelled, but this only serves to underline the point. Even the most fanatical nanny statist would hesitate before endorsing grinding poverty as a weight-loss strategy — and yet it is the only thing that seems to work. In the free world, obesity rates are flat or rising, and nowhere are they falling.
