Americans spend $40bn every year on dietary aids, and Brits would spend just as much if we hadn’t blown it all at the pub and on a curry afterwards, so we welcome a tool for crowdsourcing nutritional information, called PlateMate.
In experiments, the average of nutritional information guessed by a crowd – based on a photo of your meal that you take with your phone – was as good as a trained nutritionist, and much more accurate than reporting your own intake.
This leads us to conclude that, if you want to reduce your calorie intake by using PlateMate, the best thing to do is to stand further away from your food when you photograph it.
