As a nutritionist I have always been a keen fan of fasting. So when the 5:2 diet hit the headlines a couple of years ago, I happily embraced this form of intermittent fasting for the sake of my health as well as my waistline!  I prefer to call it a version of fasting rather than a 'diet', we all know they don't work, in the long run, for weight loss.  But this one does and the health benefits go way beyond losing a few pounds.
