I've just started the 5:2 diet and am on my first week. I've fasted 2 days so far (500 cals - well, 450 or thereabouts) and I'm actually finding it really good. I've tried so many other ways of dieting, including daily calorie counting/restriction, and I just can't stick to it and have ballooned to my heaviest ever, in the obese category and have been very worried about my health. This week has been mentally so good - I've felt positive, that I *can* do this, and I don't have that constant pressure/feeling of failure that I have with regular calorie counting.
I'm really excited about this and happy to find somewhere to learn from others' experiences & support each other!
