Focus on fitness not fatness – Why food taxes are missing the point

Focus on fitness not fatness – Why food taxes are missing the point

Researcher at the University of Essex, children’s fitness expert Dr. Gavin Sandercock writes in BBC news that we have been looking at obesity the wrong way, leaving the harm generated by physical inactivity aside.

 

Dr. Sandercock points out that reports alerting on an “obesity time-bomb” are multiplying. But according to him, the extent of the problem is often exaggerated. Figures from the National Child Measurement Programme for 2010-2011 estimate that 9% of 5 to 6-year-olds are obese, that is, Dr. Sandercock says, 2.7 children out of 30 in a class. It was 1.5 in 1990. He underlines that an “epidemic” is a term corresponding to the increase of one child per class in 20 years and suggests that childhood obesity are somewhat plateauing (25 for 2-5-years-olds boys, 23% for girls between 2003 and 2013).

 

Furthermore, Dr. Sandercock says that public health keeps being focused on food and obesity, and overlooks physical activity. As dietary guidelines vary with time, some propose to tax “unhealthy foods” as a way to tackle obesity. He underlines that we are missing the point by putting the focus on taxes. Healthy eating cannot be the only answer to obesity: physical activity is the key feature to keep in mind.

 

Those observations are corroborated by studies made in Australia in 2011, by the Snowdon report “The Fat Lie” in 2014, and most recently by Ekelund et al. 2015.

 

Quoting the British Heart Foundation 2015 figures, Dr. Sandercock shows that none of 11-15 year-old girls do enough exercise, and only 7% for boys. He calls for 60 minutes of exercise for children and young people each day and praises iniatiatives on physical activity launched around UK. To conclude, he points out that physical activity will not solve all obesity issues, but will benefit to all.

The fat lie: Britain’s rising obesity unmasked

The fat lie: Britain’s rising obesity unmasked

New research suggests the UK’s rise in obesity has not been caused by, as many have suggested, high-fat foods and sugary drinks but by a lack of physical activity.

Conducted by the Institute of Economic Affairs (IEA), the briefing paper argues against the claim that calorie consumption has been the primary cause of the UK’s expanding waistline. Indeed, according to the IEA the evidence overwhelmingly suggests that per capita consumption of sugar, fat and calories has been falling in the UK for several decades.

The Fat Lie examines evidence from the Department for Environment, Food and Rural Affairs, the National Diet and Nutrition Survey, the ONS and the British Heart Foundation.

The average weight of an English adult has increased by two kilograms since 2002. Yet over the same period calorie consumption fell four per cent and sugar consumption dropped nearly 7.5 per cent. The amount of calories consumed outside the home also tumbled from 310 in 2001/02 to 219 in 2012.

But while Brits were cutting back on cake, physical activity has also taken a back seat. In 2010 the average Brit walked 179 miles – compared with 255 miles in 1976.

Cycling had also dropped to an average of 42 miles a year by 2010, compared with 51 in 1976.

As many as 40 per cent of people reported spending no time walking at work. The IEA points out that the rise in sedentary office jobs and labour-saving devices mean people are not compelled to undertake the same amount of physical activity they used to.

Report author Christopher Snowdon said: “With obesity now featuring so heavily in the media it is worrying that so few people know that our largely sedentary lifestyles, not our appetites, have been the driving force behind the UK’s expanding waistlines”.

The report draws three key findings from the evidence gathered, the first being that the food industry, which has been the target of increasingly polemical public health campaigns, is not the main culprit for rising obesity. It could also put paid to some campaigners who argue that bans and taxes on certain types of food and drink could significantly reduce obesity numbers.

Second, while people tend to play fast and loose with the amount they say they eat, it remains “extremely unlikely” that the almost uninterrupted fall in calorie consumption is down to people telling fibs about how much they eat.

Furthermore, the report argues a one-size-fits-all solution is inadequate when it comes to reducing obesity. The report acknowledges while average calorie consumption has fallen this does not mean everyone is eating less; however, the IEA urges scepticism about claims that cutting the UK’s calorie intake will reverse the rise in obesity.

Inactivity, not calorie consumption, behind rising obesity in the UK

Inactivity, not calorie consumption, behind rising obesity in the UK

New research finds UK’s rise in obesity has been primarily caused by a decline in physical activity

The rise in obesity amongst the UK population has been primarily caused by a decline in physical activity. Using government figures, this new study debunks the popular belief that the rise in obesity in recent decades is the result of increased calorie consumption in general, and sugar in particular.In The Fat Lie, Christopher Snowdon studies evidence from DEFRA, the National Diet and Nutrition Survey, the ONS and the British Heart Foundation, finding that all the evidence indicates that per capita consumption of sugar, fat and calories has been falling in the UK for decades.Despite public health campaigners portraying Britain’s obesity ‘epidemic’ as a result of increased availability of junk food, this conventional wisdom has no basis in fact. People have reduced the number of calories they consume, but have reduced the amount they move around even more.

 

Key statistics:

  • Since 2002, the average body weight of English adults has increased by two kilograms. This has coincided with a decline in calorie consumption of over 4% and a decline in sugar consumption of nearly 7.5%.
  • Of food eaten outside the home, daily calories consumed have fallen from 310 in 2001/02 to 219 in 2012, a drop of nearly one hundred calories per day in ten years.
  • Data for eating out does not go back prior to 2000, but we do know that Britons were consuming more calories in the home in 1974 than Britons consumed in and outside the home combined in 2012.
  • Despite falling calorie intake, average body mass has increased by 5 kilograms since 1993. The crucial missing variable, often overlooked by campaigners, is energy expended.
  • Britons walk an average of 179 miles a year, down from 255 miles in 1976 and also cycle less; averaging 42 miles a year compared to 51 miles in 1976. 40% of people report spending no time even walking at work. The rise of office jobs and labour saving devices means people have fewer opportunities for physical activity, both at work and at home


Key findings:

  • ‘Big Food’ is not to blame

Food supply is a more inviting target for health campaigners than the sedentary lifestyles of the general public. A war on the food industry requires no stigmatisation of individuals and there are a readymade set of policies available which have been tried and tested in the campaigns against tobacco and alcohol.

  • Under-reporting of eating habits does not change conclusions

Although measuring the diet can be difficult because people tend to downplay the amount they eat, the question is not whether people under-report but the extent to which under-reporting has changed over time. It is extremely unlikely people have become so forgetful that the large and virtually uninterrupted fall in calorie consumption reported in successive studies can be explained by misreporting.

  • A one-size-fits-all response is not the solution

The fact that Britons, on average, are eating fewer calories does not mean that everybody is eating less, but we should be sceptical about those who claim that reducing calorie intake across the population will lead to less obesity. That clearly hasn’t happened in the past.

 

Commenting on the report, its author, Christopher Snowdon, said:“The root cause of Britain’s rising obesity levels has not been a rise in calorie intake but a rise in inactivity. With obesity now featuring so heavily in the media it is worrying that so few people know that our largely sedentary lifestyles, not our appetites, have been the driving force behind the UK’s expanding waistlines.

“Campaigners promoting a healthy lifestyle should refocus their efforts towards encouraging exercise and away from a war on food. Anti-market policies aimed at the whole population such as fat taxes will do nothing for the nation’s health.”
