Labels showing exercise needed to burn off calories ‘could help weight loss’

Food labels telling people how much exercise is needed to burn off what they eat could be more effective at helping weight loss than just listing the amount of calories., a new study has claimed.

The Royal Society for Public Health says most people do not understand the meaning of calories and fat levels in terms of energy balance.

It has been calling for the introduction of "physical activity calorie equivalent or expenditure" (Pace) food labelling. It tells consumers how many minutes or miles of exercise they need to do to burn off the calories in a particular product.

Now research from the Loughborough University appears to back up this approach, predicting the system could shave off up to around 200 calories per person each day on average if widely applied.

The team, using data from 14 trials, found that 65 fewer calories per meal were selected when Pace labelling was used, and 80-100 fewer calories consumed, equating to 200 calories per day.

The researchers say the difference, although not huge in itself, could be meaningful as regular over-consumption of small amounts of calories is a key contributing factor to population-level obesity.

A report last month from Diabetes UK found that 13 million adults in the UK are obese, with NHS national medical director Stephen Powis describing obesity as "a dangerous public health threat".

Publishing their research in the Journal of Epidemiology & Community Health, the authors of the Loughborough study concluded that "Pace labelling is a simple strategy that could be easily included on food/beverage packaging by manufacturers, on shelving price labels in supermarkets, and/or in menus in restaurants/fast-food outlets.

"Public health agencies may want to consider the possibility of including policies to promote (it) as a strategy that contributes to the prevention and treatment of obesity and related diseases."

They did however caution that many of the studies from which the data was drawn were not carried out in real-life environments, such as restaurants and supermarkets.

They said the effects of Pace labelling could vary according to context, with marketing, time constraints and price all likely to affect choices.

Duncan Stephenson, deputy chief executive of the Royal Society for Public Health, said: "We welcome this new research which builds the case for introducing activRead More – Source
