I did intermittent fasting for more than 3 years after watching the Michael Mosely documentary about it. I found it was a really easy way for me to keep my weight down without having to worry about what I was eating.

Then we had a load of family weddings, parties, holidays etc and I was only able to do 1 day rather than 2 days a weeks. As a result I started putting on weight.

So I switched back to more healthy eating 7 days a week and haven't gone back to the intermittent fasting. I might do it again soon though because, according to the documentary, there are heart health benefits to it.

I found it easiest to eat nothing until I had a latte at 3.00 with an oak cake. Then I would have meal of around 350 in the evening.

I know a number of people who have done it though and everybody finds their own way. I also found it helped to have a big meal the night before the second fast of the week!

Good luck with the challenge!
