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

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

But when we looked at the packaging time of 6 seconds, it was too late to make such a complicated measurement.

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

A number of studies have confirmed that labeling energy alone does not significantly improve people’s diet choices.

It was found that it was indeed effective, and then many experiments were gradually carried out around this theme.

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

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

Do you choose the left or the right? | Reference [2] Compared with only indicating energy, the effect of restricting diet with exercise volume label is obviously better.

In this study, the label only appears in lunch, far away from the time when you can exercise after work..

People of different ages, weights, exercise levels and physical conditions have different energy consumption during exercise.

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

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

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

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

The calculation is too complicated.

Do you forget to exercise? When you eat, remind you that the exercise volume label not only brings back our optimistic estimation of energy, but also always appears in front of you to remind you of exercise.

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

Stick to exercise, but gain weight.

Most people just glance at the “crispy”, “rich” or “buy and give” and start.

Although this is only for the current meal, it is not clear whether it will last [4-6], if the role of the exercise volume label can be maintained, the energy intake of about 200 kilocalories can be reduced throughout the day, and the long-term weight loss effect is considerable.

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

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

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

While we underestimate our intake, we also overestimate the energy we consume.

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 kilocalories on average, the actual consumption energy decreased by 80.4 kilocalories, and the weight decreased by 27.1 grams.

It’s beyond your imagination that “I’m tired after running for an hour! I want to eat fried chicken, cola, cake, milk tea…” Many people have trained themselves to be very fat.

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

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

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

At the same time, due to everyone’s need to control diet and lose weight, they tested the impact of exercise volume label on diet choice for the first time in 2012 [3].

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

The energy consumption varies with different weight and body type.

The researchers labeled the same working lunch with energy or exercise amount respectively.

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

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

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

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

A recent study confirmed that people do exercise more.

A recent study published in the Journal of Epidemiology and Community Health synthesized 15 trials with high quality in the past to analyze people’s response to this “cruel” label.

But if the package of potato chips you often buy suddenly shows that “the energy contained needs to run for an hour to consume”, will you feel that its taste is not worth the hard work of sports, and you will replace it with a healthier snack nearby? Figure 1 Why does GIPHY appear such a “cruel” label? The researchers didn’t mean to ruin your mood, because the food labels were more and more detailed, but people didn’t choose a healthier diet.

Compared with the fast food that is defined as unhealthy, people will further underestimate the energy of 20%~25% when eating healthy food.

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

The exercise volume label is simple and crude, but effective researchers anticipated your hesitation.

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

And no matter it is dinner, snacks or drinks, the indicator of exercise volume has a role.

They say they should lose weight and limit their dietary energy, but they can’t remember at this time.

The creativity of Tu Bug is cruel.
