From how 5:2 works and what to eat, to tips on getting through those fast days, read our guide to intermittent fasting.
Anyone else grumpy on fast days?
Um, it's because you're hungry. Your body is designed to take in food and drink on a regular basis to keep it going and it complains if it doesn't get it.
Caitlin Moran's article in the Saturday Times magazine is well worth a read. No, you aren't alone.
Will see if I can locate that article. Have tried my best not to be grumpy but its definitely there!
