Want an extra slice of pizza? Be prepared to walk 43 minutes

Last Updated Apr 7, 2016 at 9:12 am EST

It can be tough to figure out how much exercise you need to do to burn off all the food you eat, but in England, one researcher wants to make it easier.

For example, if you want an extra slice of pizza, you should be prepared to walk an extra 43 minutes. A can of pop, meanwhile, is a 40-minute stroll.

That’s the advice from Shirley Cramer, chief executive of the Royal Society for Public Health, who is calling for labelling similar to cigarette warnings on food.

Cramer believes many consumers find nutrition labeling confusing, with lots of information that is hard to make sense off, so she came up with the idea of a catchy infographic that shows both the calories in the item and how much exercise it would take to burn it off.

It’s just a proposed idea for now, but the objective is to encourage people to be more mindful of the calories they consume. According to a piece written by Cramer on the BBC, the infographic would also encourage people to be more physically active.

Advocates say it would be an effective way to help fight rates of obesity and diabetes, while critics worry that it could lead to calorie counting. It could also reinforce the belief that exercise is the key to weight loss.
