I've been doing it for about 3 months, and roped in DH too. We have both lost about a stone each, and I am very impressed by how easy it is, having previously tried low carb, low GI etc. DH has actually taken to it far better than I expected, and he is diabetic. He's never even moaned! I don't feel faint, rosesarered , in fact, the theory is that you shouldn't on one day's fast, because in ancient times it was when you ran out of food that you needed to go out and catch more! I do find I stick to the same few meals (hardly recipes) on fast days, and to begin with I was meticulous about weighing absolutely everything. I am a bit more casual now. I think the best part is that it always only one day: "I can't have that roast potato / biscuit/ whatever today, but I can tomorrow". There isn't the same feeling of being permanently deprived, so it is easier to stick to. Good luck OP and anyone else thinking of starting!
