Britons count sex as exercise, Italians dance to stay in shape and Danes love to bike. This is according to data crunched by Swedish weight-loss app Lifesum, which analysed the health habits of 100,000 registered users from their database of 6.5 million downloads.

The ioses and androids app, which asks users to enter what they eat and how they exercise daily, has collected over one million data points from its users around the world. So, at Wired's request, Lifesum trawled its data banks to compare the food and exercise habits of the UK, Sweden, Italy, Germany and Denmark for our infographic. "I was surprised that less than ten per cent of our users in each country logged running, even though it's one of the easiest ways to stay in shape," says Lifesum nutritionist Lovisa Nilsson. "There's more walking and bicycling -- these are in the top-three exercises for every country." So who comes out as healthiest? "Denmark eats dark bread, a lot of root and green vegetables and fruit -- these are high in fibre, which is why they have the lowest calorie intake," says Nilsson. Bottom of the list are Germany and the UK -- "The Germans eat a lot of deli and luncheon meats, which are high in saturated fats and salt; the British count chocolate and crisps in their top-ten foods." (Here, we've compared the best and worst countries for you.)

Next, the firm wants to give you personalised advice on improving your fitness routines. "We're crunching the data to help you change your daily behaviours," says Lifesum's CEO Henrik Torstensson. Put down the cake, and pick up your smartphones.
