I've been on the 5:2 for so long it's just a way of life now. I'm not trying to lose weight, just to stop putting any more on, so I must confess to eating too much on the non-fast days, and it's been way too much over Christmas. I reckon I could lose a few pounds if I exercised a bit of control on the 5 days too - I might give it a go just out of interest over the next couple of weeks. Starting next week. of course.
I used to be paranoid about drinks on fast days, Tegan, just having fruit tea and flavoured fizzy water. I still find the fizzy water to be a real help, but I just have my usual tea with milk now during the day. There's only around 10 calories in a cup. I have nothing to eat at all during the day, then a tea of 400 calories, which sets me up for the evening. I used to find that if I ate at all before tea time it made me hungrier.
