2013 world’s most beautiful woman Gwyneth Paltrow is a known health nut but I doubt many know exactly how much Ms Paltrow puts into her health.

According to Daily mail’s report the Iron Man's star wears a bracelet that controls her activity levels, advices her on meals and it vibrates when she’s lazy.

The £99 band  uses a built-in motion sensor and Motionx GPS to register the time you spend walking, running or just sitting around. It vibrates if you've been inactive for too long, and a 'stopwatch' lets you note the start and end of specific workout sessions.

It works alongside a smartphone app, which estimates the calories burned. You can input your mood into the app or scan the barcodes on your shopping to calculate your calorie intake.

Everything is relayed back to you as a message on your phone and through vibrations in the wristband, with suggestions for ways you can live more healthily.

The wristband uses Actigraphy - a sensor which measures tiny movements to determine whether you are awake or in a light or deep sleep. With these, it calculates the optimum time to wake you each morning with a gentle vibration through the wristband.
