A third of children are now said to be overweight By Richard Vadon BBC Radio 4's The Investigation Britons are getting bigger and it's a crisis on the same level as climate change, says the government. Within 15 years most of us will be overweight, with our life expectancy cut by 13 years. Scary stuff, but do all the facts about this "ticking time bomb" really add up?A third of children are now said to be overweight By Richard Vadon BBC Radio 4's The Investigation Britons are getting bigger and it's a crisis on the same level as climate change, says the government.

The Investigation is broadcast on Thursday, 22 November at 2000 GMT on BBC Radio 4 Radio 4's The Investigation There's just one problem with this claim - official forecasts show it's not true. The government-commissioned Foresight report released last month [see internet links, right] looked at the future trends of obesity and found an increase will have surprisingly little impact on life expectancy. In fact it predicted Britons will live significantly longer.

The UK is certainly getting heavier.

"If you look at men they have become around half a stone heavier on average than they were in 1993," says Heather Wardle, a senior researcher at the centre."If you look at men they have become around half a stone heavier on average than they were in 1993," says Heather Wardle, a senior researcher at the centre.
This weight gain matters because it means more and more of us are becoming overweight and unhealthy, argue anti-obesity campaigners. Putting any weight on after your 21st birthday is even a risk, according to last month's World Cancer report.This weight gain matters because it means more and more of us are becoming overweight and unhealthy, argue anti-obesity campaigners.

No one denies extreme obesity is bad for you, but some are now standing up to defend the overweight. Professor John Evans, from the School of Sport and Exercise Sciences at Loughborough University, doesn't believe the predictions.No one denies extreme obesity is bad for you, but some are now standing up to defend the overweight.

"There is very little evidence to say that being overweight is a signifier of a person or a population's health," he says."There is very little evidence to say that being overweight is a signifier of a person or a population's health," he says.
This may sound like heresy but there is good science to back it up. Only this month a study, led by Katherine Flegal of the USA Centre for Disease Control, reported that those who are overweight had no higher risk dying of cancer or heart disease and overall lived longer than those of "normal" weight. You might be surprised at her finding but she was not.This may sound like heresy but there is good science to back it up.

"Overall there is no evidence of a strong increase in risk in being overweight, but there is evidence of a significant increase for people who are obese," says Doctor Gillian Reeves, who led the study."Overall there is no evidence of a strong increase in risk in being overweight, but there is evidence of a significant increase for people who are obese," says Doctor Gillian Reeves, who led the study.

One of the most alarming statistics about obesity is that a third of children are now overweight. We are told that weight is now even a problem among the youngest school children.One of the most alarming statistics about obesity is that a third of children are now overweight.

An estimated 25% of 5-year-olds are now overweight, according to the government's Health Survey for England. That might be the statistic, but some are still sceptical.An estimated 25% of 5-year-olds are now overweight, according to the government's Health Survey for England.

Some evidence suggests the overweight live longerWhen you visit schools it's certainly hard to find these large numbers of overweight kids. Doctor Linda Voss is the co-ordinator of the Early Bird Study, which is looking at the links between childhood obesity and diabetes. Put on the spot in a school even her expert eye failed to spot these numbers of fat kids.Some evidence suggests the overweight live longerWhen you visit schools it's certainly hard to find these large numbers of overweight kids.

But another reason we can't see them could be because the figures are misleading. The figures the government use are based on a 1990 benchmark. It put the weight and height measurements from different surveys on a graph and decided that the top 15% of kids would be called overweight and the top 5% obese. As our children have got heavier, more and more have passed these benchmarks.But another reason we can't see them could be because the figures are misleading.

But the UK's way of calculating obese and overweight children isn't the only one. If we adopted the international standard we would roughly cut our figures for fat children in half.But the UK's way of calculating obese and overweight children isn't the only one.

Experts like Professor Cole say that whatever figures you use, the underlying trend is going up. But critics say big scary statistics are a good way to unsettle the public and justify government intervention.Experts like Professor Cole say that whatever figures you use, the underlying trend is going up.

It's predicted obesity will cut life expectancy by 13 yearsAt last month's annual conference of the National Obesity Forum there was a vote of no confidence in the government policy on dealing with Britain's weight problem.It's predicted obesity will cut life expectancy by 13 yearsAt last month's annual conference of the National Obesity Forum there was a vote of no confidence in the government policy on dealing with Britain's weight problem.
Forum board member Tam Fry was one of those who spoke out against the government. He has worked for a charity for years to publicise the risks of obesity. Yet he is obese himself.Forum board member Tam Fry was one of those who spoke out against the government. He has worked for a charity for years to publicise the risks of obesity.

The obesity statistics are full of people, who like Tam, are fine at their weight. It's the small minority of very obese that are the problem, not the two-thirds of us the government defines as overweight.The obesity statistics are full of people, who like Tam, are fine at their weight.
