A girls' school is banning wearable activity trackers and smart watches because of concerns that pupils are skipping lunch if they fail to meet their calorie and exercise targets. Teachers at Stroud high school in Gloucestershire fear the gadgets are exacerbating some girls' worries about their body image. The deputy headteacher, Cindi Pride, said the school's active and healthy pupils did not need to count calories and the number of steps they took each day. She said: “We are banning Fitbits and smartwatches. These monitor the number of calories burned and we found that some girls would monitor the number of steps they had taken and the number of calories they had used. If they didn't feel they had taken enough steps in the morning, they wouldn't eat lunch.
