In this study, the label only appears at lunch, which is far from the time when you can exercise after work.

Moreover, the promotion of healthy food has a certain confusing effect.

The exercise volume label not only brings back our optimistic estimate of energy, but also always appears in front of us to remind you of exercise.

The energy of the same cake can be consumed by one person running for half an hour, while the other person may need an hour.

But we can’t make such a complicated measurement when we look at the packaging in 6 seconds.

If people are required to eat food with the same energy after exercise, most people will eat 2-3 times as much energy as they just consumed [12].

The researchers labeled the same work lunch with energy or exercise volume respectively.

Most people just glance at “crispy”, “rich” or “buy as a gift” and then start.

Insist on exercise but gain weight.

When evaluating the amount of exercise, the number of people who think they exercise less is less than half of the actual number, while the number of people who think they exercise more is at least twice the actual number [11].

Many studies have confirmed that only labeling energy can not significantly improve people’s diet choices.

However, only one certain number can be written on the label, so it is roughly estimated based on the average consumption of people [5].

But if the package of potato chips that you often buy suddenly shows that “the energy content needs to be consumed by running for an hour”, will you feel that the taste of it doesn’t match the hard work of sports, and replace it with a healthier snack nearby? Figure 1 Why is there such a “cruel” label in giphy? The researchers did not deliberately destroy your mood, because the food labels were more and more detailed, but people did not choose a healthier diet.

The results showed that it was indeed effective, and then many experiments were gradually carried out around this theme.

A recent study confirmed that people do exercise more.

“It’s tiring after running for an hour! I want to eat fried chicken, coke cake, milk tea.

It’s beyond your imagination.

In addition, whether it is dinner, snacks or drinks, the indicator of exercise volume has a role.

If the energy is converted into equivalent specific amount of movement, it is much more convenient to prominently mark it on the front of the package [2].

Only dieters have more accurate estimation, and may have more experience in estimation due to long-term attention to energy [8].

And when people reduce the total energy of a meal, they will give priority to reducing desserts and beverages [7].

The creative reality of Tuchong is cruel.

The calculation is too troublesome.

In addition, the label is difficult to include the energy needed to repair the body after exercise, which may slightly overestimate the amount of exercise required.

However, the exercise volume label sacrifices some accuracy while being concise.

Compared with the definition of unhealthy fast food, people will further underestimate the energy of 20% – 25% when eating healthy food.

After one year, compared with the employees who ate energy labeled food, the weekly exercise time of the people who contacted the exercise volume label increased by 13% to 26% [13].

In a single exercise, people’s estimate of exercise energy consumption can be as high as 3-4 times the actual value, and the deviation of different exercise types and intensity estimates is also different [8].

They can’t remember the good words of losing weight and limiting dietary energy at this time.

Do you choose left or right? [1Reference [2] Compared with labeling energy only, the effect of exercise volume label on diet restriction is significantly better.

People with different age, weight, exercise level and physical condition have different energy consumption during exercise.

A recent study published in the Journal of Epidemiology and Community Health analyzed people’s response to this “cruel” label by integrating 15 previous high-quality trials.

The exercise volume label is simple and crude, but the effective researcher predicted your hesitation, and at the same time, forced by everyone’s need to control diet and lose weight, tested the effect of exercise volume label on diet choice for the first time in 2012 [3].

Indeed, if you want to know the energy of a packet of potato chips, you should first look at the energy of each food, multiply it by the content of the whole package, and then calculate whether it can be eaten.

Although this is only the effect of the current meal, and it is not clear whether it can be sustained later [4-6], if the effect of the exercise volume label can be maintained, it can reduce the energy intake by about 200 kilocalories a day, and the long-term weight loss effect is considerable.

Do you forget to exercise? Remind you when eating.

The energy consumption varies with different weight and body type.

The results showed that when the amount of exercise needed to consume food energy appeared on the package or menu, the total energy of the food people chose decreased by 64.9 kcal on average, the actual consumption energy decreased by 80.4 kcal, and the weight decreased by 27.1 g.

On average, it takes only 6 seconds for everyone to choose the food to buy [1].

In a meal of 836 kilocalories, people will underestimate 175 kilocalories on average, and the more they eat, the greater the deviation [9].

While we underestimate our intake, we also overestimate our energy consumption.

This is the reason why some people become fatter as they practice, and also the advantage of the exercise volume label.

This is not only good for losing weight, but also good for health.

When estimating dietary energy, at least two thirds of people will underestimate it.

When you see that the energy of a pizza needs to walk for 4 hours to consume, while a salad only takes 15 minutes, you may also change your choice.

Not to mention the detailed information about fat and carbohydrate, most people have not even read the energy and are unwilling to calculate the meaning of that long series of figures.

If the required walking time or length appears on the food label, most people feel that it will increase their exercise volume [7].

Most people underestimate dietary energy and overestimate exercise consumption, so we will be surprised to see the amount of exercise on the label.

Two thirds of healthy people will underestimate their meditation time [10].
