Food packaging should have labels that tell you how much exercise is required to burn off the calories consumed, as it could help tackle the obesity crisis.
According to researchers from Loughborough University, this kind of labelling has the potential to cut about 200 calories from a person's daily average intake. The labels would show people just how many minutes of running or walking are needed to burn off the food.
The labels would help inform people so they'd indulge less and could even prevent people from overeating, or inspire them to workout.
The researchers also suggested that it might encourage food producers to make products with less calories.
