Should we label food by exercise needed, not calories?

An interesting study led by Sunaina Dowray, a student at the School of Medicine of the University of North Carolina, looked into the impact on people’s habits if they were shown one of four different menus, giving them the food’s calorie count, the time it would take to walk those calories off, the distance it would take to burn them, or none of this extra information.

People who viewed the menu without nutritional information ordered a meal with up to 200 kcals more than those with the exercise information.

This wasn’t in the real world- it was a hypothetical test online. But the results are promising; saving just 100 kcal twice a week could add up to over a kilo of weight loss over one year.
