Nutrition Labels with Exercise Info: How Many Minutes to Burn Off that Chocolate Bar?

Are you confused by the nutrition information listed on product packaging? You’re not alone.

A recent study found that 80% of participants wished that food labeling was easier to understand. Moreover, people had a hard time translating abstract nutrition information – like the calories in a chocolate bar – into concrete, real life examples.

For the University of Canterbury study, which included 220 people, muesli and chocolate bars were used to determine how different product labeling affects exercise. Simply labeling the bars with their caloric information was determined to have little or no impact on exercise.

Researchers then converted the calories into their exercise equivalent. The nutrition labels read, “You will need to jog for 40 minutes to burn off the calories in this chocolate bar.” The response was markedly different – and participants’ exercise increased as a result. They were also less likely to eat the chocolate bar in the first place.

While people might not understand 500 calories, a 40 minute jog translates into real life experience. Unfortunately, it’s really an oversimplification. The amount of calories you burn on a 40 minute jog depends on a number of factors, including the speed of that jog and how much the individual weighs. And it still doesn’t tell the full story – like how much fiber, sugar, sodium, fat or saturated fat is in a product. Simply stating an exercise equivalent doesn’t tell you how healthy a product is.

Researchers point to peanut butter as a perfect example. It will take you longer to burn off a tablespoon of peanut butter than jelly – but peanut butter, which is loaded in good fat and nutrients, is much healthier than sugary jam.

It may be a step in the right direction, but there’s still no clear-cut solution to the problem of product labeling.

  1. Difficult one as food labels are misleading anyway like ‘low fat’ etc etc maybe a picture of bad teeth or v obese person on the chocolate bar? Odd how adverts always feature slim people.

  2. I think people need to be more cognizant of the ingredients in the food they eat. Like you said, peanut butter (even better, almond butter!) is much healthier than Smuckers jam. So if you look at the labels of two products and they have equal calories, look down at the ingredients. Is the first ingredient high fructose corn syrup or sugar? If so, you might want to put it down and back away slowly.

  3. Most processed peanut butters like Jif and especially Skippy are loaded with sugar!

  6. I do not know whether it’s just me or if perhaps everyone else encountering issues with your blog. It appears as though some of the written text in your posts are running off the screen. Can somebody else please provide feedback and let me know if this is happening to them as well? This could be a issue with my browser because I’ve had this happen
    before. Cheers
