Still associated with efforts to prevent childhood obesity epidemic, researchers from Johns Hopkins University concluded that the duration writing exercise that must be done in every food and beverage packaging is effective for reducing cravings.
They claim that includes physical activity equivalent to the amount of calories diasup far more effective than just write down the number of calories contained in food products or beverages.
To test the theory they put three different warning for a food product. The warning was posted in the glass of the shop so it is easy to read the teenage consumers they target.
The first written warning can of soda contains 250 calories. Both states are calories in a can of soda 10 per cent of daily calorie recommendation. Meanwhile a third warning states that we should go jogging 50 minutes to burn these calories from soda.
Apparently a third warning is much more effective. Perhaps because it is more easily understood and the consequences to be borne feel burdensome.
Previously, studies show that nutrition information contained in the packaging of soda has cut sales to 40 percent. With the addition of the warning of the consequences of exercise is expected to reduce sales by 50 percent.
