Well realistically the weight loss should only be 1lb if you do the maths. To lose 1lb of fat requires you to eat 3500 cals fewer than you need. If you can eat 2000 cals a day without gaining weight,the fast days at 500 per day only take you to 3000 fewer,so slightly less than 1lb burnt off. This doesn’t take into account extra exercise etc and some research says ‘not all calories are the same’ Go figure! It’s a complicated business. I exercise a lot and my average weight loss has been about 1.5lbs a week,but,like you sylvestra,I’m grateful for small mercies and to have found a way of losing weight that is the easiest I’ve ever managed.
