Future iPhones or Apple Watches may be able to help users with calorie counting, alongside the step-tracking and other information they already help us keep tabs on.

That’s according to a newly-published Apple patent, which describes device-readable RFID tags the company has invented. These could be used to send nutritional information — such as caloric value, fat and sugar content, and more — from food packaging to your NFC-enabled Apple device.

Most fitness apps seem obsessed with calories. Go for a run, and your Apple Watch tells you how many calories you burned. Scan a barcode and MyFitnessPal tells you how many calories are in the food you are about to eat.

So what exactly are calories, and does counting them really help you achieve your fitness goals?

Of course, it isn’t easy. Luckily, those of a certain nerdy bent will find all the motivation they need in gadgets and apps. I have been doing just that for the past few months, and I thought I’d write a little about how to get thinner and fitter by using your iPhone.
