Calorie labels fitted to staircases Using a dedicated website and app, people will be able to scan "smart signs" on stairs and track their number of calories burnt over time. The initiative is already being adopted by a number of City firms as well as county council buildings in Hertfordshire. Boris Johnson, the Mayor of London, said: "Anything that gets people more active and helps tackle obesity is a good thing in my book. This initiative is a great mix of old fashioned common sense and smart technology to track and incentivise. StepJockey's website will allow anyone to map and rate a set of stairs for calorie burn, and print off posters which can be added for others to use. Lord Howe, minister for health, said: "It is really important that we all do as much exercise as we can to reduce the risk of preventable illness and lead longer, healthier lives. Tackling inactivity is one of the challenges facing the NHS today and one of the reasons why we have awarded StepJockey funding through our £50 million Small Business Research Initiative. Helen Nuki, founder of StepJockey, added: "We tell people how many calories are in food but we don't tell them where they can burn them off. The world is a gym and we aim to label it as such. It has the added benefit of cutting carbon emissions by reducing the number of lift journeys.
