In a wave of schoolgirl nostalgia, the marie claire team has signed up for this weekend’s 40-hour famine, the annual fundraiser for World Vision. We were happy to hear that things had changed since we last joined in back at school, where we gorged ourselves silly on the only food that wasn't banned: barley sugars.

The rules seem a lot more lenient these days. In fact, you don’t even have to go without food. Instead you just have to forego something that you love for 40 hours. Here’s a round-up of what some of our staff have already promised: features editor Daniela isn’t touching any foods with nasty sugar; sub-editor Leanne is foregoing all things chocolate; our associate editor Alex has pledged to give up alcohol; artist Mel promises she won't nag her husband; while all the girls in fashion said they'd give up social media (but we knew they were joking).

The rest of the team is still deciding, and we’ll fill you in as the countdown marches on.

The famine officially starts at 8pm this Friday and goes through to midday on Sunday. Check out the details here or if you have already signed up, tweet us or upload pics and let us know how you're going at #MC40HF.

And in the spirit of the Famine, tell us what you COULDN'T give up for 40 hours.
