Does including exercise on food labels cut calorie intake?

Alerting people to the fact it will take 45 minutes of running to burn off the calories in a pizza or 13 minutes per can of soft drink is an effective way to encourage healthier food choices, a study suggests.
UK researchers analysed 14 studies into PACE (Physical Activity Calorie Equivalent) labelling on food, drinks and menus to see if adding this information led to a reduction in calorie intake compared with current calorie-only labelling or no labelling.
They found that PACE did, in fact, lead to fewer calories being consumed.
On average, those who were exposed to PACE labelling ate 65 fewer calories per meal than those who were exposed to calorie-only labelling or no labelling.
