The calculation is too complicated, and the exercise label is concise and rough.
However, effective researchers anticipate your hesitation, and at the same time, due to the need for people to control their diet and lose weight, they first tested the impact of exercise labels on dietary choices in 2012.
And we didn’t have time to make such complex measurements when we looked at the packaging in 6 seconds.
The results showed that it was indeed effective, and multiple experiments gradually revolved around this topic.
And whether it’s dinner, snacks, or drinks, the indicator of exercise volume has a role
.
Indeed, to know the energy of a bag of potato chips, one needs to first look at the energy of each food, multiply it by the content of the entire packaging, and then calculate whether it can be eaten.
A recent study published in the Journal of Epidemiology and Community Health analyzed people’s reactions to this “cruel” label by combining 15 previously high-quality trials.
They can’t remember the good things about losing weight and limiting dietary energy.
Do you choose left or right? Reference [2] has a significantly better effect on restricting diet with exercise volume labels compared to only indicating energy.
When you see that a pizza requires 4 hours of walking to burn its energy, while a salad only takes 15 minutes, you may also change your choice.
Multiple studies have confirmed that labeling energy alone does not significantly improve people’s dietary choices.
But if the packaging of frequently purchased potato chips suddenly says “the energy content needs to be consumed by running for an hour”, will you feel that its taste doesn’t match the hard work of exercise and switch to healthier snacks nearby? Why is there such a “cruel” label in the picture? Researchers do not intentionally disrupt your mood, it is because food labels are becoming more detailed, but people have not chosen a healthier diet.
Most people just glance at “crispy”, “rich”, or “buy as a gift” and then start.
On average, it takes only 6 seconds for everyone to choose the food they want to buy.
Not to mention the detailed information about fats and carbohydrates, most people have not even looked at energy and are unwilling to calculate the meaning of that long string of numbers.
If energy is converted into an equivalent specific amount of exercise, it will be much more convenient to prominently label it on the front of the packaging.
The results showed that when the amount of exercise required to consume food energy appeared on the packaging or menu, the total energy of the food people chose decreased by an average of 64.9 kcal, the actual consumption energy decreased by 80.4 kcal, and the weight also decreased by 27.1 grams.
